that already works by default but it can be messy (inefficieint)

with MW set to 0.19 and Einstein set to 0.33 I ended up after while with one MV taking 0nly 1/5 of gpu and one Einstein taking only 1/3 of the same one and wasted gpu time.

Normally 3 Einstein on one gpu or 5 MW but if both enabled then things get haphazard quickly.

I haven't tried this, but I suppose you could set the resource share for all projects to 0. Additionally, you could set all projects to No New Tasks. Then, whenever you want to run Boinc, you could select the project you want to run and Allow New Tasks. With the resource share at 0 it should only download enough tasks for the processors you have active. When you don't want that project to download any further tasks you can set it back to No New Tasks. If you don't want all CPU cores to crunch tasks, follow Les' advice and reduce the percentage.

I know this seems to make running Boinc quite a bit more manual than automatic, but I'm guessing you are okay with that.

There hasn't been any Linux work at climateprediction for ages.
And you don't really have enough memory for that project anyway.

Recent announcement from Alessio Mereghetti... https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5011

This is a major rebuild of LHC's SixTrack app moved from testing to production. WinXP is not supported but they're working on fixing that.
ATM there are 750K tasks available. Get 'em while they're hot!!

Thanks, was a fan of CERN hoping they could find a small black hole to prove the critics were correct and they could inadvertently destroy the world.

..I quit reading when I got to the "huge source files and Fortran90" statement.

They need to get on the GPU band wagon.
That being said, I am crunching on their stuff.

Calling someone a climate denialist likens them to holocaust deniers and is an insult and lack of civility.

Not when those denying the scientific consensus are doing so because of vested interests rather than a genuine belief that the scientific consensus is wrong. (I know people who genuinely believe that all the talk about climate change is a conspiracy along with vaccination, the introduction of 5G and much else besides.) I have long since given up arguing with them about it.

The last time I got into a discussion about this topic I got put on the stop forum spam list and took me a week to get off. I no longer crunch any climate related projects and never will as only a moderator or project insider could do that.

There is some issues with University Data Center. Currently unknown how long it will take to restore availability of the server. No worries, no data was lost. Just server of this project and probably some others that are hosted in the same University Data Center.
Thank you for understanding

My point, dear child, is that if other applications - from indie games to web browsers to modellers to commercial games - can work just fine being accelerated by my iGPU using the current driver, then it seems like it ought not to be impossible for BOINC to do the same.

Now if that is in the too hard basket to get working again, fine. iGPU workunit crunching is surely a niche in BOINC. Priorities, right? But kindly do end your patronising BS that I'm suggesting or not knowing things that I never suggested and know very well indeed, thank you.

Yeah, I do actually know a driver is, and one is installed, thanks very much you patronising person. That's why I can run hardware accelerated apps on a monitor plugged into my iGPU :-) If a multitude of games and 3D apps - commercial to homebrew, even web browsers can run and be accelerated by my iGPU using the installed driver, I would think BOINC ought to manage...
