Hi,

I'm trying to run the new Mac CUDA app on Primegrid - other users have reported it is working, so I'm guessing it's a client config issue, but I can't figure it out. I've got 'Use GPU always' selected, but the tasks never run. The is the latest alpha version BOINC manager for Mac OS X:

see http://www.pyramid-productions.net/downloads/BOINC.png for a screenshot, showing CPU tasks running, but not GPU tasks.

I made a copy of the files in my 'BOINC Data' dir here http://www.pyramid-productions.net/downloads/BOINCData.tar.gz - if that helps to figure out what is set wrong...

Any ideas would be appreciated, I'd love to get my GPU crunching!

Thanks in advance,

What's the memory requirement for Primegrid? Others have reported that Mac OS X desktop effects can use a lot of GPU RAM, and your 254 MB isn't a lot to start with.

This could be the problem - is the VRAM requirement something that can be set by the project to stop WU's being downloaded if they can't be run?

It can be set somehow in the server plan_class for the application, but I'm not an expert on that.

You might want to compare notes with Oliver Bock at Einstein, who has run into similar problems - read message 102091 and the discussion leading up to it.
