Project progress and summer period // Avance del proyecto y período estival
Dear volunteers,
First of all, please excuse me because I wanted to send this message a week ago, but I was not able to do so. As you have seen these days, just like last year, we are entering the summer period, and the rate of sending simulations will be affected. We hope that it does not stop completely, but the sent tasks will be reduced.

I take this opportunity to update the results of the last months: you have been optimizing one of the most used human ventricle models: the O'Hara and Rudy model. We have tested several optimization configurations and have obtained a new adjustment for the model that improves its behavior in relation to a large number of markers reported in the scientific literature. There is still a configurations that has not been finished, but we are already beginning to prepare a scientific publication that summarizes our results. As soon as it is finished and published (it is a long process), we will share it with you and explain it.

In the coming months we will begin to optimize a version of this widely used model, which is the basis of a new model we are developing to study heart failure. We will take advantage of this change in model to automate some things, so the slow pace of summer may be a little longer at the beginning of the school year, but with the objective that the pace will not slow down afterwards.

Thank you all very much for your understanding, and this afternoon, new tasks.

Best regards,
Jesus.

Estimados voluntarios:
En primer lugar, disculpadme porque este mensaje quería haberlo mandado hace una semana, y no pude hacerlo. Como habéis comprobado estos días, al igual que el año pasado, entramos en el período estival, y el ritmo de envío de simulaciones se verá afectado. Esperemos que no se detenga del todo pero se reducirán las tareas que enviaremos.

Aprovecho para actualizaros que en los últimos meses, habéis estado optimizando uno de los modelos de ventrículo humano más utilizados: el modelo de O'Hara y Rudy. Hemos probado varias configuraciones de la optimización y hemos obtenido un nuevo ajuste del modelo que mejora el comportamiento del mismo con relación a una gran cantidad de marcadores reportados en la literatura científica. Queda un poco para que termine una de las configuraciones, pero estamos ya comenzando a preparar una publicación científica que resuma nuestros resultados. Tan pronto como esté terminada y publicada (es un proceso largo), os la compartiremos y explicaremos.

En los próximos meses comenzaremos a optimizar una versión de este modelo que se usa mucho y que es la base de un nuevo modelo que estamos desarrollando para estudiar la insuficiencia cardiaca. Aprovecharemos este cambio de modelo para automatizar algunas cosas, así que igual el ritmo lento de verano se alarga un poco al comienzo de curso, pero con la idea de que después no baje el ritmo.

Muchas gracias a todos por la comprensión, y esta tarde, tareas nuevas.

Un saludo,
Jesús.

Hard drive space crisis solved // Crisis de espacio en el disco duro resuelta
Dear volunteers,
This weekend we have broken a new record for computing Teraflops (since we are in this new stage of the project). This is thanks to the pace of sending results that you have been doing in recent days and being more stable in the generation of work packages.

Although we were monitoring it, the coincidence of this peak with the database backup on the weekend has caused the hard drive to become saturated sooner than expected. We have been working since Monday on moving data out of the server and even other processes, but as we gained space it kept filling up with results that were pending upload.

This morning, for the first time in two days, more tasks have been validated than have been received and little by little normality will return. At first, it doesn't seem like anything has been lost and we are already submitting work again.

We have expanded the space to receive results and are working on automating some of the tasks to ensure we can continue to grow.

Thank you all very much, if we have this type of problems it is because of the great support you give us, we will continue working to grow by your side.

Sorry for not answering in the forums, and thank you very much for be aware of the evolution.

All the best,
Jesus.

Estimados voluntarios:
Este fin de semana hemos batido un nuevo record de Teraflops de computación (desde que estamos en esta nueva etapa del proyecto). Esto es gracias al ritmo de envío de resultados que estáis haciendo en los últimos días y de estar más estables en la generación de paquetes de trabajo.

Aunque ibamos monitorizándolo, la coincidencia de este pico con la copia de seguridad de la base de datos en el fin de semana ha hecho que se saturara el disco duro antes de lo esperado. Hemos estado trabajando desde el lunes en mover datos fuera del servidor e incluso otros procesos, pero según ganábamos espacio se seguía llenando con los resultados que estaban pendientes de subir.

Esta mañana, por primera vez en dos días se han validado más tareas de las que se han recibido y poco a poco se irá retomando la normalidad. En principio, no parece que se haya perdido nada y ya estamos enviando trabajo de nuevo.

Hemos ampliado el espacio para recibir resultados y estamos trabajando en automatizar algunas de las tareas para garantizar que podemos seguir creciendo.

Muchas gracias a todos, si tenemos este tipo de problemas es por el gran apoyo que nos dais, seguiremos trabajando para crecer a vuestro lado.

Disculpad que no haya contestado en los foros, muchas gracias por estar tan pendientes de la evolución.

Project status update // Actualización del estado del proyecto
Dear volunteers,
I am writing to update you on how the different experiments we had launched have been going and the next steps we will take.

On the one hand, we have finished (at least temporarily) the optimization of our model. As we had already told you, with the results that you have sent us, we managed to greatly improve how our model represented different physiological markers, but a problem that we thought we had solved had reappeared. We have tried different options but it reappeared in all of them. That forces us to stop and take steps back in the definition of the model, so, for the moment, we will not be launching new simulations in NHuVe.

On the other hand, as we had told you, we are trying to use our optimization algorithm in another existing model. The results seem to be very good, but we have to work in parallel on their validation.

In the coming weeks we will be working on requesting funding from the Government of Aragon for a new research project that will use DENIS as a computing platform, so you may have noticed that our activity has decreased a little. If this goes well (hopefully!) we will keep you informed, but keep in mind that these things are slow so the answer will take months to arrive.

Thank you all very much for staying there and for your support.

Sincerely,
Jesus.

==================================================================

Estimados voluntarios:
Os escribo para actualizar cómo han ido yendo los diferentes experimentos que teníamos lanzados y los próximos pasos que seguiremos.

Por un lado, hemos terminado (al menos temporalmente) la optimización de nuestro modelo. Como ya os habíamos comentado, con los resultados que nos habéis ido mandando conseguíamos mejorar mucho cómo nuestro modelo representaba diferentes marcadores fisiológicos pero había reaparecido un problema que creíamos haber solucionado. Hemos probado diversas opciones pero en todas ellas reaparecía. Eso nos obliga a parar y dar pasos atrás en la definición del modelo, por lo que, por el momento, no estaremos lanzando nuevas simulaciones en NHuVe.

Por otro lado, como os habíamos adelantado, estamos probando a utilizar nuestro algoritmo de optimización en otro modelo ya existente. Los resultados parecen ser muy buenos, pero tenemos que ir trabajando en paralelo en la validación de los mismos.

En las próximas semanas estaremos trabajando en pedir financiación al Gobierno de Aragón para un nuevo proyecto de investigación que utilizará DENIS como plataforma de cómputo por lo que habréis notado que ha bajado un poco nuestra actividad. Si esto saliera bien (¡ojalá!) os mantendremos informados, pero contad que estas cosas son lentas así que la respuesta tardará meses en llegar.

Muchas gracias a todos por seguir ahí y por vuestro apoyo.

Atentamente,

Reduction in the number of tasks during the month of August // Reducción en el número de tareas durante el mes de agosto
Dear volunteers,
We are approaching the month of August in which the university rests for vacations. While we may not stop completely, the number of tasks available this month will be fewer. Our attention to the state of the server will be reduced, so we do not want to take the risk of saturating it.

Between the 20th to 28th the stop of new tasks will be total, resuming normal activity from the 29th or 30th.

I take this opportunity to tell you that the different variations of the optimization are continuing, in some cases it seems that we could obtain better results, but we are going to be cautious, when they are finished we will inform you of the final result.

Good summer everyone.

All the best,
Jesus.

Entre los días 20 a al 28 la parada de nuevas tareas será total, retomandose a partir del día 29 o 30 la actividad normal.

Results and new simulations // Resultados y nuevas simulaciones
Dear volunteers,
I am writing to update you on how the project is going and the results we are obtaining.

First of all, the optimization of the new model we are developing has already finished (the first one we released). Unfortunately the results have not been as expected. The optimization has worked very well and many markers have been improved, but one of the model issues that we are trying to fix has reappeared after the optimization. We think we understand where the problem is coming from and why it seemed like we fixed it, but really didn't. If we are right, this will require rethinking the model and starting over. Before starting again, we are testing various optimization settings to try to optimize the model without getting to the point where the problem reappears. We're not sure if it will work (this is science), but before we have to start over, we want to test this option.

On the other hand, some of you have already noticed that we are launching work in the Beta version. One of our pending projects was to use DENIS not only to improve the model we were developing, but also to try to improve other existing models. Let's start with this part of the project. For now, we will use the O'Hara and Rudy model, one of the most used in research. We have released the simulations in Beta version because we have never tested this model in DENIS before, but they will soon be released in HuVeMOp.

Finally, you may have noticed that we have run out of space a couple of times lately: the increase in the number of simulations requires more speed to get the results out and post-process them. We are working on further automating these processes in order to continue growing.

Thank you all very much for your support of the project and we will keep you informed of new developments.

Sincerely,
Jesus.

=====================================

Estimados voluntarios:
Os escribo para actualizaros cómo va el proyecto y los resultados que estamos obteniendo.

En primer lugar, la optimización del nuevo modelo que estamos desarrollando ya ha terminado (la primera que lanzamos). Lamentablemente los resultados no han sido como esperábamos. La optimización ha funcionado muy bien y se han mejorado muchos marcadores, pero uno de los problemas del modelo que estabamos intentando solucionar, ha reaparecido tras la optimización. Creemos entender de dónde viene el problema y por qué parecía que lo habíamos solucionado, pero realmente no lo habíamos hecho. Si estamos en lo cierto, esto requerirá replantear el modelo y comenzar de nuevo. Antes de recomenzar de nuevo, estamos probando varias configuraciones de la optimización para intentar optimizar el modelo sin llegar al punto en el que reaparece el problema. No estamos seguros de si funcionará (esto es ciencia), pero antes de tener que volver a empezar, queremos probar esta opción.

Por otro lado, algunos ya habéis notado que estamos lanzando trabajo en la versión Beta. Uno de nuestros proyectos pendientes, era utilizar DENIS no solo para mejorar el modelo que estabamos desarrollando, sino para intentar mejorar otros modelos ya existentes. Vamos a arrancar con esta parte del proyecto. De momento lo haremos con el modelo de O'Hara y Rudy, uno de los más utilizados en investigación. Hemos lanzado las simulaciones en la versión Beta porque nunca habíamos probado este modelo en DENIS, pero en breve pasarán a lanzarse en HuVeMOp.

Finalmente, habréis notado que nos hemos quedado un par de veces sin espacio últimamente: el aumento en el número de simulaciones requiere mayor rapidez a la hora de sacar los resultados y post procesarlos. Estamos trabajando en automatizar más estos procesos para poder seguir creciendo.

Muchas gracias a todos por vuestro apoyo al proyecto y os mantenemos informados de los nuevos avances.

Atentamente,
Jesús.

Status of the project // Estado del proyecto
Dear volunteers,
We update you on the status of the project and how the simulations are going. In recent weeks the search algorithm has been improving the model very little. This indicates us that the optimization is close to be finished. Once this is complete we will pass to the validation phase which we will be done outside of DENIS (DENIS is not yet prepare for the required simulations).

The improvement obtained is very considerable (you can see the graph with the evolution of the error below and we hope that the validation results turn out well). It can be improved, but not all the error can be removed with the optimization (it requires other type of improvements in the model).

On the other hand, looking at the results, last week we started a new optimization by changing an aspect of it. In the initial search, if one of the markers was in the experimentally observed range, we did not allow the algorithm to search where that marker was outside of the experimental range (criterion of keeping at least those markers that were already in the experimental range). In the new search we are allowing it in the hope that even if some marker goes out, the overall behavior will improve. In this case, the uncertainty about the result is higher, but as you can see in the graph below, after the first iterations of the algorithm, the results are quite promising.

Sincerely,
Jesus.

========================================

Estimados voluntarios:
Os actualizamos el estado del proyecto y cómo van las simulaciones. En las últimas semanas el algoritmo de búsqueda ha ido mejorando muy poco el modelo. Esto nos indica que está a punto de terminarse la optimización. Una vez que esto se complete, pasaremos a una fase de validación de la simulación que haremos fuera de DENIS (DENIS no está preparado para ello).

La mejoría obtenida es muy considerable y esperamos que los resultados de la validación salgan bien (podéis ver la gráfica con la evolución del error debajo). Todavía hay margen de mejora, pero no todo el error se puede eliminar en la optimización (requiere otro tipo de mejoras en el modelo).

Por otro lado, viendo los resultados, la semana pasada comenzamos una nueva optimización cambiando un aspecto de la misma. En la búsqueda inicial, si uno de los marcadores estaba en el rango observado experimentalmente, no permitíamos al algoritmo buscar donde ese marcador saliera del rango experimental (criterio de mantener en rango experimental al menos los que ya estaban). En la nueva búsqueda estamos permitiéndolo con la esperanza de que aunque algún marcador salga fuera, el comportamiento global mejore. En este caso la incertidumbre sobre el resultado es algo mayor, pero como podéis ver en la gráfica de debajo, tras las primeras iteraciones del algoritmo, los resultados son bastante prometedores.

Atentamente,
Jesús.

Dear volunteers,
Allow me a brief message to update you on how the results are going after 15 more days of simulation.
5 iterations of the algorithm have already been completed. Of the 100 markers that we are using, 89 have already been achieved in the normal range (initially only 77 were). On the other hand, the distance between the average experimental behavior and the model has been reduced by 56.84%.

Several parameters of the algorithm indicate that there is still room for improvement.

We will keep you informed.

Results of the first iteration of the algorithm // Resultados de la primera iteración del algoritmo
Dear volunteers,
We have good news! After processing the results of the first iteration, we have found a combination of model parameters that improves the behavior of the model compared to the initial one. In the original version, of the 100 markers that we are using, 77 were in the experimental range: now there are 80. On the other hand, the distance between the model and the average experimental behavior has been reduced by almost 30%.

The values of several of the parameters that have been modified are in the limit of the area that we had used in the first iteration, so the search area has been expanded (this is parameterized in the algorithm).

The tasks of the second iteration are already being sent. We will continue to inform you of how the results are going.

Thank you very much to all!

Por otro lado, la distancia entre el modelo y el comportamiento medio experimental se ha reducido casi en un 30%.

Los valores de varios de los parámetros que se han modificado estan en el límite de la zona que habíamos utilizado en la primera iteracción, así que se ha ampliado la zona de búsqueda (esto está parametrizado en el algoritmos).

Results of the last simulations and next steps // Resultados de las últimas simulaciones y siguientes pasos
Dear volunteers,

I have both good and bad news to share with you regarding our recent progress. First, the good news: thanks to the results you've sent in, we have been able to identify the problem with the marker and gain a better understanding of what was happening. Additionally, it turns out that we won't need to increase the number of simulations per iteration, which is good news (for us).

However, there is also some bad news to report. We've discovered that the behavior of the model with this marker is highly non-linear, which means that it cannot be effectively addressed within the framework of our current approximation. While this could be disappointing, we can assume this limitation in the model, as it was measured experimentally under unrealistic conditions.

Once we've fine-tuned the model, we will determine whether this non-linear behavior persists, or whether it disappears with the changes we've made. If the issue does persist, we'll need to address it in the next phase of our work, which means there may be more work to come for some of you. We'll keep you updated on our progress.

We're grateful for your continued efforts and support.

Best regards,
Jesus.

===========================================

Estimados voluntarios:
Tengo noticias buenas y malas que compartir con vosotros sobre nuestro progreso reciente. Primero, las buenas noticias: gracias a los resultados que habéis enviado, hemos logrado identificar el problema con el marcador y obtener una mejor comprensión de lo que estaba sucediendo. Además, resulta que no necesitaremos aumentar el número de simulaciones por iteración, lo cual es una buena noticia (para nosotros).

Sin embargo, también hay malas noticias que reportar. Hemos descubierto que el comportamiento del modelo con este marcador es altamente no lineal, lo que significa que no puede ser abordado de manera efectiva dentro del marco de nuestra aproximación actual. Si bien esto puede ser decepcionante, podemos asumir esta limitación en el modelo, ya que se midió experimentalmente en condiciones poco realistas.

Una vez que hayamos ajustado el modelo, determinaremos si este comportamiento no lineal persiste o si desaparece con los cambios que hemos realizado. Si el problema persiste, tendremos que abordarlo en la siguiente fase de nuestro trabajo, lo que significa que puede haber más trabajo por hacer para algunos de ustedes. Os mantendremos informados sobre nuestro progreso

Muchas gracias por vuestro esfuerzo y apoyo continuo.

New simulations // Nuevas simulaciones
Dear volunteers:
As we had indicated in previous messages, we had to stop fitting the model because there was an experiment that we could not fit well. After analyzing our results, we believe that one of the limiting factors could be in the number of simulations we do to fit the behavior of the model in the experiment. Therefore, before continuing with the model fit, we are going to do a new test to study this in detail. We just put in new simulations to help us analyze this experiment to see if we can improve the model and its fit.

Thank you for your patience during this break. After analyzing the results of this experiment we hope to be able to resume the simulations.

Best,
Jesús

Estimados voluntarios:
Tal y como os habíamos indicado en mensajes anteriores, habíamos tenido que parar el ajuste del modelo porque había un experimento que no conseguíamos ajustar bien. Después de analizar nuestros resultados, creemos que uno de los factores limitantes podría estar en el número de simulaciones que hacemos para ajustar el comportamiento del modelo en el experimento. Por ello, antes de continuar con el ajuste del modelo vamos a hacer una nueva prueba para estudiar esto en detalle. Acabamos de poner nuevas simulaciones que nos ayuden a analizar este experimento para ver si podemos mejorar el modelo y su ajuste.

Gracias por la paciencia en este parón. Después de analizar los resultados de este experimento esperamos poder retomar las simulaciones.

Temporary stop of tasks // Parada temporal de las tareas
Hello everyone:
First of all, excuse these days without notices from us, but the start of the course has required more time than we expected and we have not been able to be as active as we would like in the project.

We update you on how the optimization of the model is going: after 3 iterations of the algorithm, the model is gradually improving, but one of the markers is greatly limiting the improvement. We full understand why this is happening, so we need to stop and analyze it in detail before continuing.

Thanks to all the simulations you have done we have a wide variety of situations to study and we hope to resume the simulations shortly (ideally 1 week, but it is easy for it to be two).

On the other hand, the applications that we had in Beta mode have already been sufficiently analyzed to be considered stable, and until we modify the application again, the beta tasks will be stopped.

Thank you very much and we will keep you informed shortly.

All the best,
Jesus.

Hola a todos:
En primer lugar, disculpad estos días de parón sin notificar, pero el arranque de curso nos ha requerido más tiempo del que esperábamos y no hemos podido estar todo lo activos que querríamos en el proyecto.

Os ponemos al día de cómo va la optimización del modelo: tras 3 iteraciones del algoritmo, el modelo va poco a poco mejorando, pero uno de los marcadores está limitando muchísimo la mejoría. No tenemos del todo claro por qué está sucediendo, pero necesitamos para y analizarlo en detalle antes de continuar.

Gracias a todas las simulaciones que habéis hecho hasta el momento tenemos gran variedad de situaciones para estudiar y esperamos reanudar las simulaciones en breve (idealmente 1 semana, pero es fácil que sean dos).

Por otro lado, las aplicaciones que teníamos en modo Beta están ya suficientemente analizadas como para considerarlas estables, y hasta que no modifiquemos de nuevo la aplicación, las tareas beta estarán paradas.

Status of the proyect // Estado del proyecto
Hello!
I am writing this post to summarize a little the news that we have had over the last month. As we have already commented on the forums, we detected a problem with the checkpoint files that caused many windows tasks to end with an invalid result. After several tests and several attempts we have managed to detect where the problem was and solve it. Due to this, we have implemented some of the improvements that we had planned for the checkpoint file. We have made it more robust. We have kept it as beta for quite a few days and it seems that the problem is fixed. We will continue to analyze how the program works, but the percentage of errors that we receive is more than reasonable in a project of these characteristics.

A special thanks to all of you who have been giving us feedback and helping us find the problem.

Today we have re-launched simulations in the NHuVe project. These tasks are no longer beta. We will inform you of the status of that project as we receive results. In the coming weeks we also plan to add tasks to the HuVeMOp project. With both projects working we hope to have a fairly stable flow of tasks.

On the other hand, we have been working on expanding the number of platforms and we have added in beta mode an application for ARM64 on linux (e.g. RaspberryPi), and ARM for Apple (for new Apple chips). We want to see how well they work. If all goes well, in the short term we could also consider expanding to Android.

All the best,
Jesus.

==========================================

Hola!
Os escribo este post para resumir un poco las novedades que hemos tenido a lo largo del último mes. Como ya hemos comentado por los foros, detectamos un problema con los ficheros de checkpoint que hacía que muchas tareas de windows terminaran con un resultado invalido. Después de varias pruebas y varios intentos hemos conseguido detectar dónde estaba el problema y solucionarlo. Debido a esto, hemos adelantado algunas de las mejoras que teníamos pensadas para el fichero de checkpoint y hemos aprovechado para hacerlo más robusto. Hemos mantenido la versión beta durante bastantes días y parece que el problema está solucionado. Seguiremos analizando cómo funciona el programa, pero el porcentaje de errores que recibimos es más que razonable en un proyecto de estas características.

Un agradecimiento especial a todos aquellos que nos habéis estado dando feedback y ayudando en la búsqueda del problema.

Gracias a esto, hoy hemos vuelto a lanzar simulaciones en el proyecto NHuVe. Estas tareas ya no son beta. Os iremos informando del estado de ese proyecto según vayamos recibiendo resultados. En las próximas semanas planeamos también añadir tareas al proyecto HuVeMOp. Con ambos proyectos en marcha esperamos tener un flujo bastante estable de tareas.

Por otro lado, hemos estado trabajando en ampliar el número de plataformas del proyecto y vamos a poner en modo beta una aplicación para ARM64 sobre linux (e.g. RaspberryPi), y ARM para Apple (para los nuevos chips de Apple). Queremos ver qué tal funcionan. Si todo va bien, en un corto plazo nos podríamos plantear también ampliar a Android.

Estimados usuarios:
Con un poco de retraso respecto a nuestra idea original, el próximo jueves 7 de julio, relanzaremos el proyecto DENIS.

Durante los próximos días iremos actualizando la web y algunas funcionalidades por lo que es posible que algunas cosas funcionen mal temporalmente. Cuando todas las modificaciones se hayan completado os avisaremos. Si veis algún fallo antes de ese aviso, no os preocupéis por lo que pueda funcionar mal.

No obstante, si algo os genera dudas, podéis preguntarnos en los foros.

Muchas gracias a todos por vuestra paciencia.

Results of the second phase of application testing // Resultados de la segunda fase de pruebas de la aplicación
Dear volunteers,
After this second phase of testing and with version 7, the results are as expected. We want to review some small detail in case we can reduce the number of errors that occur in clients. Currently they are in less than 0.5% of the cases and we believe that it is mostly due to situations in the client, but if we see options for improvement, we will do it.

With these results, we are ready to move on to the next phase, so we will be working on it for two or three weeks. We are preparing the experiment and working on a new version of the website, simpler but with more information about the experiments that we are going to start launching.

Our intention is to set an "official" relaunch date with the new experiment, so we will let you know in the coming weeks what day it will be.

Thank you very much to everyone in this beta phase, we will keep you informed as soon as possible.

All the best,
Jesus.

Estimados voluntarios:
Después de esta segunda fase de pruebas y con la versión 7, los resultados son los esperados. Queremos revisar algún pequeño detalle por si podemos reducir el número de errores que se producen en los clientes. Actualmente son en menos del 0.5% de los casos y creemos que mayoritariamente debido a situaciones en el cliente, pero si vemos margen de mejora, lo haremos.

Con estos resultados, estamos ya en disposición de pasar a la siguiente fase, así que estaremos dos o tres semanas trabajando en ello. Estamos preparando el nuevo experimento y trabajando en una nueva versión de la página web, más simple pero con más información sobre los experimentos que vamos a empezar a lanzar.

Nuestra intención es fijar una fecha "oficial" de relanzamiento con el nuevo experimento, por lo que os avisaremos en las próximas semanas de qué día será.

Muchas gracias a todos en esta fase beta, os mantenemos informados lo antes posible.

Second phase of application testing // Segunda fase de pruebas de la aplicación
Dear all,
After the second batch of simulations the result were similar: 99.5% of the simulations endend satisfactorily; 0.5% returned apparently normal but with invalid values. These results are stable enough to be able to perform a larger test. We actually need it to know if this small percentage of errors is due to something in the code or something in the clients. Currently the number of users returning invalid results is so low that it is hard for us to figure out what the difference might be.

So, we have decided to continue to the second phase with a bigger test with 45000 working units. They are already going up. We hope they don't last long on the server!

If everything goes well in this second phase, we will probably consider the beta version stable and we will start launching the projects that we have prepared.

Thank you in advance. We will keep you update of the results.

Best,
Jesús.

Estimados usuarios:
Tras la segunda tanda de simulaciones el resultado ha sido similar: el 99,5% de las simulaciones finalizan satisfactoriamente; el 0,5 % arrojó resultados aparentemente normales pero con valores inválidos. Estos resultados son lo suficientemente estables como para poder realizar una prueba más grande. De hecho, la necesitamos para saber si este pequeño porcentaje de errores se debe a algo en el código o a algo en los clientes. Actualmente, la cantidad de usuarios que devuelven resultados no válidos es tan baja que nos resulta difícil determinar cuál podría ser la diferencia.

Por tanto, hemos decidido continuar con la segunda fase con una prueba más grande con 45000 unidades de trabajo. Ya están subiendo. ¡Esperamos que no duren mucho en el servidor!

Si todo va bien en esta segunda fase, probablemente daremos por estable la versión beta y empezaremos a lanzar los proyectos que tenemos preparados.

Gracias de antemano. Los mantendremos informados de los resultados.

Results of the first batch of simulations // Resultados de la primera tanda de simulaciones
Dear volunteers,
We are analyzing the first batch of simulations and so far the results are quite satisfactory. 98.35% of the tasks launched once the problems with the validator were solved, run without problems and their results were valid. 1.12% of them failed to boot into the client (all under the same user and host). 0.53% were tasks that were executed satisfactorily but whose results were not validated when comparing whit the results of the other volunteers. We are studying what could have happened in these tasks so that the result did not coincide with those of the other. As soon as everything is checked, we will repeat the test and if everything goes well, we will move on to a larger test.
Thank you very much to all, we keep you informed of the progress.

Data protection // Protección de datos
Dear users,
With the update of the boinc version and the relaunch of the project, there was an important change that we had forgotten to mention. Since the last time the project was in operation, the data protection regulation and also our perception of it has changed. Due to this, with the new version of BOINC we have taken the opportunity to give you the greatest possible control over your data and what can and cannot be done with it. That is why, by default, we do not assume any permission to export your data and make it available to statistical websites.

If you want your data to be available, you must explicitly indicate it at: https://denis.usj.es/denisathome/prefs.php?subset=project (you can access this web from your profile).

boincstats.com has indicated to us that they are waiting to update the statistics so that more users can accept the export. Otherwise, the statistics of those who have not accepted it will be deleted.

Continuing with this topic of data protection, we wanted to inform you that, for the relaunch of the project, this project has been presented and approved by the ethics committee of the San Jorge University as it is a project in which personal data could be processed.

We hope that this new operation does not cause you any inconvenience, but transparency is very important to us and you must have control over the handling of your data.

Sincerely,
Jesus.

=================================================

Estimados usuarios:
Con la actualización de la nueva versión de boinc y el relanzamiento del proyecto, había un cambio importante que se nos había olvidado comentar. Desde la última vez que el proyecto estuvo en funcionamiento, la normativa de protección de datos y también nuestra percepción de la misma ha cambiado. Es por ello que con la nueva versión de BOINC hemos aprovechado para daros el mayor control posible sobre vuestros datos y sobre lo que se puede y no se puede hacer con ellos. Es por ello, que por defecto no asumimos ningún permiso para exportar vuestros datos y que estén disponibles para webs de estadísticas.

Si queréis que vuestros datos estén disponibles, debéis indicarlo explícitamente en: https://denis.usj.es/denisathome/prefs.php?subset=project (podéis acceder desde vuestro perfil).

Desde boincstats.com nos han indicado que están esperando a actualizar las estadísticas para que más usuarios puedan aceptar la exportación. En caso contrario se borrarán las estadísticas de quienes no lo hayan aceptado.

Continuando con este tema de protección de datos, queríamos haceros partícipes de que, para el relanzamiento del proyecto, este proyecto ha sido presentado y aprobado ante el comité de ética de la Universidad San Jorge por tratarse de un proyecto en el que se pueden tratar datos personales de los voluntarios.

Esperamos que este nuevo funcionamiento no os genere molestias, pero para nosotros es muy importante la transparencia y que tengáis el control del manejo de vuestros datos.

Atentamente,
Jesús.

Problems with the validator solved // Problemas con el validador solucionados
Good afternoon to everyone,
The problem with the validator has already been solved and currently the project is stable and processing the data that is arriving. We will continue to check if there is any other problem with the database, but it seems that the problem that caused the crashes has already been solved.

Soon we will launch another small batch of simulations to evaluate how the program is working. We have detected that in a few cases unexpected results return and we want to analyze well under which situations occur before massively launching the simulations.

Thank you very much to all of you who are testing the beta version, it is very helpful.

All the best,
Jesus.

===========================================================

Buenos tardes a todos:
El problema con el validador ya ha sido solucionado y actualmente el proyecto está estable y procesando los datos que van llegando. Seguiremos atentos por si hubiera algún problema más con la base de datos, pero en principio parece que el problema que generaba que se cayera, ya está solucionado.

En breve lanzaremos otro pequeño lote de simulaciones para ir evaluando cómo está funcionando el programa. Hemos detectado que en unos pocos casos vuelven unos resultados no esperados y queremos analizar bien bajo que situaciones ocurren antes de lanzar masivamente las simulaciones.

Muchas gracias a todos los que estais probando la versión beta, nos es de mucha ayuda.

Recovering lost credits / Recuperando los créditos perdidos
Dear volunteers,
First of all, I hope that all of you and those close to you are well in this global pandemic.
This week is the anniversary of one of the hardest moments of this project. Three years ago, during a database update, it was corrupted. With this failure we detected that the backup system of the data base was not working as it should and we were only able to restore a 6-months-old backup. All this situation coincided just at the moment in which we stopped having a person dedicated full time to the project, which supposed an added difficulty.
The results sent by the volunteers were saved in another system and only the tasks in progress were affected.
The main loss of information was the credits obtained by the different volunteers. At that time we were able to recover a large part of them, but all the accounts created between January and June were lost.

Your support and understanding during those days was enormous. However, as I told you at the time, being able to return the credits to you was an important issue: it is the only way we have to thank you for all the support for the project.

Since then, several of you have asked me if we could recover the credits from those accounts, and I didn't want to let it go any further. It was not an easy job because we had the credit information but not a system to connect them with the new accounts you were creating. Thanks to the existence of Boincstats.com and the BOINC cross project identifier, part of you will be able to recover your credits. I have been able to find almost 300 of those accounts on Boincstats.com, and in the next few days, through Boincstats.com, I will send you a link to recover lost credits. You will receive a personalized URL that will add the lost credit to your user and will correct the date since you are collaborating with us. I will send the messages in several days so that Boincstats.com does not exceed the limit of messages it can send. I want to publicly thank Will for allowing me to use his platform for all this messages. I will notify you when all are sent.

If you don't have an account on Boincstats, you can create it and associate it with the BOINC projects you collaborate on. I will periodically search for new users to whom we can return credits.

If you have any idea to associate your old accounts with the current ones, do not hesitate to contact me, we will find how to prepare it.

This is the first step to gradually start up this project again. You are an incredible community that we do not want to miss. Unfortunately, we cant afford to hire someone full time for the project so we will go very slowly. We have tried several times to obtain founds for the project and we have had good evaluations, but not enough to get them. We will continue working on it, but until we get it, we will go slowly.

Thank you very much, you have me at your disposal and I hope that, little by little, you will be receiving more messages from me.

Greetings,
Jesus.

Estimados voluntarios:
Lo primero de todo espero que todos vosotros y vuestras personas cercanas estéis bien en esta pandemia mundial.
Esta semana es el aniversario de uno de los momentos más duros de este proyecto. Hace tres años, durante una actualización de la base de datos, ésta se corrompió. Con este fallo nos dimos cuenta de que el sistema de copia de la base de datos no funcionaba como debería y sólo pudimos restablecer una copia con 6 meses de antigüedad. Toda esta situación coincidió justo en el momento en el que dejamos de tener una persona dedicada a tiempo completo al proyecto, lo que supuso una dificultad añadida.
Los resultados calculados por los voluntarios se guardaban en otro sistema y sólo se vieron afectadas las tareas que estaban en marcha.
La principal pérdida de información fueron los créditos obtenidos por los diferentes usuario. En aquel momento pudimos recuperar gran parte de ellos, pero todas las cuentas creadas entre enero y junio se perdieron.

Vuestro apoyo y comprensión durante aquellos días fue enorme. No obstante, como os dije en aquel momento, para mí el poder devolveros los créditos era un tema importante: es la única forma que tenemos de agradeceros todo el apoyo al proyecto.

Sois varios los que desde entonces me habéis preguntado si podríamos recuperar los créditos de esas cuentas, y no quería dejarlo pasar más. No era un trabajo fácil porque teníamos la información de los créditos pero no un sistema para conectarlos con las nuevas cuentas que estabais creando. Gracias a la existencia de Boincstats.com y de un identificador de BOINC interproyectos, parte de vosotros podrá recuperar sus créditos. He podido encontrar casi 300 de esas cuentas en Boincstats.com, y en los próximos días, a través de Boincstats.com, os enviaré un enlace para poder recuperar los créditos perdidos. Recibiréis una URL personalizada que al entrar en ella con vuestro usuario de DENIS, os añadirá el crédito perdido y corregirá la fecha desde la que estáis colaborando con nosotros. Mandaré los mensajes en varios días para que Boincstats.com no supere el límite de mensajes que puede enviar. Quiero agradecer públicamente a Will, que me permita utilizar su plataforma para un envío masivo de mensajes. Cuando todos estén enviados os avisaré.
Si no tenéis cuenta en Boincstats, podéis crearla y asociarla a los proyectos en los que colaboréis. Periódicamente buscaré si hay nuevo usuarios a los que podamos devolver los créditos.

Si se os ocurre algún otro sistema para asociar vuestras antiguas cuentas con las actuales, no dudéis en contactarme, buscaré la forma de ponerlo en marcha.

Este es el primer paso para ir poniendo poco a poco en marcha de nuevo este proyecto. Sois una comunidad increíble y no se os puede desaprovechar. Por desgracia, no podemos contar con alguien a tiempo completo por lo que iremos muy despacio. Hemos intentado varias veces obtener financiación para el proyecto y hemos tenido buenas evaluaciones, pero no lo suficiente para llegar a ser financiados. Seguiremos trabajando en ello, pero hasta que lo consigamos, iremos despacio.

Muchas gracias, me tenéis a vuestra disposición y espero que poco a poco vayáis recibiendo más mensajes míos.

Un saludo,
Jesús.

Thanks to beta testers
Dear volunteers,
The role of beta tester is crucial for the development of this project. They compute when errors can easily occur and risking not getting a reward in the form of credits. From today, we want to thank all these volunteers a little more for their work and we want to do it in a public way. We have added a new badge for Beta testers and a new classification with the credit obtained in beta applications (http://denis.usj.es/denisathome/top_beta_users.php). Now you can identify them easily.

Thank you very much for your commitment to the project.

Status of the project
Dear volunteers,
First of all, I want to apologize for the long time since the last update of information. As I explained in other thread, we had a database crash. This problem coincided in time with a change of work of Joel, so I was alone to manage the crisis.
Unfortunately, due to other research and teaching commitments, I cannot now devote enough time to the project to be ready and re-generate results. So I had decided to stop it temporarily. I hope to restart the project in January or February. I'll let you know by using this forum and the other official channels of the project.
Finally I want to resume the status of the recovery and the project:
• All the volunteers, hosts and teams created before 2017 have recovered they credit.
• To those ones created after January 2017, if you have computed for the DENIS project in a computer with other BOINC projects, we will be able to recover the credit through the BOINC Cross project ID. You have to add the project to a computer with the other projects and your BOINC Cross project ID will be updated to the oldest one. I’m not sure but I think that the update will take place after computing for the project. Once the project updates your CPID, I will be able to identify you in the stat files to restore your credit. I will analyze it again the next month.
• If you are not in the previous situation, please, contact me if you want to recover your credit and we will try to find any other mechanisms to identify you in the stat files.
• After the recovery, the last version of the app that was compiled and uploaded by Joel is not working. I think that the problem is in the code and not in the DB crash, but I need time to analyze the app, and to learn how the system to compile the apps and to upload them works.

Actually, the major limitation to continue with the project is the time I have available for been developing it. This project is very important for me personally and more after seeing the great welcome you have given and the great support received. Thank you once again for your patience, your support and for been here. I hope I can live up to how much you have given.

Kind regards,
Jesús.

Dear volunteers,
Next week, I will attend the 61st Annual Meeting of the Biophysical Society in New Orleans. During the conference I will present a modification of one of the currents of our model (the calcium current). This current was modified to solve some problems of the model. We decided to modify this current thanks to the results obtained in DENIS, so we can say that this is the first scientific result in cardiac electrophysiology obtained thanks to your collaboration. Thank you very much!

You computed the exploratory study to locate the part of the model that was causing the problem. Thanks to your collaboration we were able to find it and propose a solution.

Launch of new Application
Hi everyone,

As some of you have noticed, there are new WUs in the system. We are starting with a small peak of work, but the idea is to maintain a continuous flow of new WUs.

This new part of the project is related to a Database of markers of the simulations. We are populating a database with relevant values of the simulations to make to scientist easy the way to make a exploratory study of the model or avoid making all the time the same simulations.

We are working on the interface of this database and how to integrate in our website, also, we are developing a post to explain more this idea of the Database of markers.

BOINC transitioning to a Community Based Governance...
http://boinc.berkeley.edu/dev/forum_thread.php?id=10370

David Anderson wrote:

BOINC's funding from the U.S. National Science Foundation has ended, at least for the time being.
This funding supported me, Rom Walton, and Charlie Fenton.
We're now working on other things, although we'll stay involved in BOINC at some level.

The BOINC project will continue, and will be run according to a community-based model rather than centrally.
In essence, the people who contribute to BOINC now make the decisions about it.

This model is summarized here: http://boinc.berkeley.edu/trac/wiki/ProjectGovernance
and described in detail here: https://docs.google.com/document/d/1C6pU5RqidYBxk9oyAevm1yH1tn4Hw27oM8YpvsnR-gg

There will probably be little visible change.
The BOINC software will continue to work.
The translation system, Alpha testing project, BOINC web site,message boards, and email lists will continue to operate.
However, any new development and major bug fixes to BOINC will need to be done by volunteer programmers.
I'm confident that the BOINC community will meet the challenge.

I welcome your feedback.
Please post it to boinc_admin@googlegroups.com, a new email list for discussions about the BOINC project as a whole.

Longer WUs
Hi everyone!

After test that new versions are stable, today we launch a new set of WUs. Those are simulations of a heart cell during 1000 seconds. That will cost for you 3 times longer than the WUs that exists before ( simulations of 300 seconds)

We hope your machines enjoy the new food! :)
