8 GB per task is extreme, very few projects use that much. Many projects (apps) have a "regular" use of RAM, if this ever means anything in computing :)

Check the link I give above, you'll have an idea for all existing projects and applications, depending on the OS used.

I see this old thread and the page you mentioned still have the same issue (macOS void) : I think there is an issue with this (standard ?) page of the (Berkeley provided ?) boinc website.

I assume a github issue should be created in the boinc-site project ?

I assume what you mean is "if I have 2 boinc projects allowed on this machine and I have 8 threads available I want all tasks to be the same projects at once and not mix tasks from the different projects" when they are running ?

AFAIK the only way is that you suspend the other project(s) manually and only let "one at a time". And then you switch.

Post:
It's rare nowadays that project spend some time to implement screensavers, it's a resurgence of the time when boinc was mainly ran in screensaver mode and volunteers would fear about "permanent execution".

You can run most boinc projects without fear continuously regardless of your activity, the tasks executed are always launched using the OS low priority setup and will normally release instantly if any other process requires the same CPU amount at any time.

Maybe some GPU tasks of some projects, depending on your configuration / GPU, will make that your machine lag a lot. This is also why you have a dedicated "suspend calculation when computer is used" setup for both CPU and GPU in boinc parameters.

Size does not matter ;)

I think the amount of RAM is not directly linked to the efficiency of the calculation, a tiny algorithm can do miracles :)

It mainly depend on the type of calculation actually performed and how it is implemented in the algorithm, some will need to store big "table of result" in memory to process until the end (and maybe just keep a small fraction of it in the final outcome) and others will not rely on "what was calculated before" to reach the outcome.

There are other boinc projects that have a low RAM requirement.

Check there.

(I strongly recommend you install WUProp project on all your machines, the tasks consume hardly no resource and don't use one slot : they gather usage statists to feed the result page of the project and help the community + it also keeps track of time statistics on your own crunching and provides you wonderful stars you can add to your badge signature, based on the time spend regardless the power of your machine(s) :) )

Indeed

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

--- DENIS Myocyte Simulator ---
Version 0.18 - Beta

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

But the important thing is that there is much more work now ;)

I mean, there _was_ more work :D

It would be great to have permanent work, it's hard to maintain volunteers motivation without regular work :)

Regarding the mac / linux comparison, I forgot to mention it is in the same machine (VM linux in a mac).

In any case keep up the good work and viva boinc !

Hola ! Happy to see the project is back :)

Tasks are working fine both on macOS and a linux VM (on the same machine), which is great, not many projects maintain a mac app !

I can notice that tasks take 1h to run in the linux VM and 1h45 in the mac with native tasks (same app version / same credit at the end).

A bit sad but it is not the first time I notice such behaviour, maybe due to some compilation options ?

I now receive both "New human ventricular cell model" and "Beta of DENIS-myocyte" on my mac :)

Also on a linux VM I get both, but in there the beta is much quicker than on the mac, and I realize it is the same for NHVM = almost twice the run time under macOS (2 hours) compare to the run time in the linux VM (1 hour) inside the same iMac...

OK entonces no esta visible en los detalles de una tarea :

en el mac :

Application : Beta of DENIS-myocyte 0.13
Nom : DENIS_Myocyte_Beta_20220723083137735103_CNM_k_1b-Coppini_2000-conf_3847
État : Calculs en cours
Reçu : Lundi 25 juillet 2022 à 13:40:56
Date limite d'envoi : Vendredi 29 juillet 2022 à 07:41:24
Taille de tâche estimée : 7 896 GFLOPs
Temps de calcul : 01:02:10
Temps processeur depuis le point de sauvegarde : 00:01:16
Temps écoulé : 01:03:31

en la VM linux del mac (misma maquina) :

Application : Beta of DENIS-myocyte 0.13
Name : DENIS_Myocyte_Beta_20220723083137735103_CNM_k_1b-Drouin_ENDO_5000-conf_216
State : Running
Received : Tue 26 Jul 2022 02:28:38 PM CEST
Report deadline : Sat 30 Jul 2022 08:28:41 AM CEST
Estimated computation size : 7,896 GFLOPs
CPU time : 00:41:27
CPU time since checkpoint : 00:00:32
Elapsed time : 00:41:51

(pero confirmo que solo es un punto de display, hice un reboot de mi VM linux y siguió calculando las tareas con la duración anterior)

Otro pequeño detalle

tarea del mac : 1h46mn
tarea de la VM linux en el mac (misma maquina) : 1h06mn

Esta duraciones parecen bastante estables : la applicacion linux es mucho mas optimizada que la mac (Beta of DENIS-myocyte v0.13 para los 2).

Thanks !

I actually realize that even though it was not listed on the application page, my mac had already done a good number of beta app in the recent weeks... !?

Anyway my mac got plenty now, thanks again.

Hi

I see "New human ventricular cell model" tasks available since yesterday but my mac host can't get any, and it could at the relaunch of the project.

Since the beta are linux only, I can't help with my mac :/

I'm happy to say that all is going well on my Mac.

At l'Alliance Francophone we are quite happy to see Denis coming back and hopefully we soon have another biomed stable boinc project !
