New version with checkpoints // Nueva versión con checkpoints
(Message 3110)
Posted 26 May 2025 by  Jesús Carro
Post: Dear Volunteers, Over the past few weeks, we have been testing the server and the new application developed by Iván. After verifying that the application is running well and having a general idea of the server's limits for the application, we have just launched a new version. This new version includes checkpoints so that we can run longer simulations without issues arising from restarts. Debugging checkpoints has always been one of the most challenging aspects when developing new versions, so we will be monitoring how things progress gradually. It will remain in beta mode, so please be patient if this leads to tasks that are not validated or other types of problems. One of the risks at this stage is that if the simulation does not restart correctly at the checkpoint, it becomes corrupted and the results will not match those submitted by other volunteers. Thank you very much to everyone who is running our beta version. Without this validation, it would be unthinkable to be able to advance towards creating better simulations. Sincerely, Jesús. =============================================================== Estimados voluntarios: En las últimas semanas hemos estado poniendo a prueba al servidor y la nueva aplicación desarrollada por Iván. Tras ver que la aplicación va bien y tenemos más o menos claros los límites del servidor para la aplicación, acabamos de lanzar una nueva versión. Esta nueva versión incluye checkpoints para así poder lanzar simulaciones más largas sin que sea un problema por reinicios. La depuración de los checkpoints siempre ha sido uno de los elementos más difíciles cuando desarrollamos nuevas versiones, así que vamos a ir viendo poco a poco cómo va. Seguirá en modo beta y tened paciencia si esto genera tareas que no se validan u otro tipo de problemas, es uno de los riesgos en este punto. Si no se reinicia bien en el checkpoint la simulación queda corrompida y los resultados no coincidirán con los enviados por otros voluntarios. Muchísimas gracias a todos los que estáis corriendo nuestra versión beta, sin esta validación sería impensable poder avanzar para hacer mejores simulaciones. Atentamente, Jesús. |

Post: Yes, the blackout affected us like the rest of Spain, but DENIS was stopped without problems. It took a bit longer to return because we were among the last priorities for restoring university services. The issue with country filters is not related to this; it is a matter of the university's network policy due to the attacks received. There is a list of countries from which access to the network is not allowed, and we cannot do anything about it. I'm sorry. |

Post: Hi! Yesterday, the IT department modified the configuration again (I think is still not working...). Thank you for detecting the problem with the config file, I have solved, but I suposse it is no the cause of the other problems... Best, Jesús. |

Server out of disk space

Post: Hello everyone. Let me give some explanations regarding this topic that I think will help to understand it better. When we mark an application as beta, in some cases it is not just the application; it may be that the type of simulations we are sending are very different from what we had until now. That is, we test both the application and the server's response to the new application. And yes, this makes us push it to the limit, and more than once we have gone overboard. These new fiber simulations generate larger files (we have to adjust what and how much we can save and select it well based on the tests). On the other hand, the biggest performance issues we are observing are in the database, and although we have several possibilities, it is not clear why it is going slower. When it takes longer to process and write to the database, the server can start to fill up, and there is a critical point where everything starts to get worse. In this testing phase, we are also analyzing this. As in previous occasions, we need you to be patient. The ultimate goal is to be able to make research, and you know that in this project that involves moments of downtime. There are other types of projects that can work continuously (for example, searching for prime numbers), but in our case, it is bursts of a large number of simulations. Best. Jesús. |

Post: Hi! You are partially right. Yes, last week and this Monday were holidays at the university. We have been having server issues due to database performance, and to prevent it from worsening, I stopped the automatic task generation. My intention was for it not to stop working during those days (it had been running without any issues for several days). I have been monitoring the status of everything, but I couldn't dedicate much time, and it was the least bad solution. |

Post: I have edited the preferences and checked "Run test applications?" and "If no work for selected applications is available, accept work from other applications?". After updating the project in BOINC Manager, I got tasks. My OS is Ubuntu 24.04. This is important, remember that we are sending task in a beta application. |

Post: We have managed to clear the validation queue. Indeed, if we do not validate them, BOINC does not generate the results file... And that is our bottleneck when the hard drive fills up: without space, the server does not function properly, so it cannot validate, and there is no results file to extract from the server, which does not help to clear it... |
