Question: Is cpu-only client usable for coronavirus research?
ptrm opened this issue · 6 comments
I could not find any specific information how much non-gpu machines can be used for this specific project. In README thet's only "We're especially in need of more donors with GPUs to help out", which does not tell about how much non-gpu machines can help. I have a i7 laptop with intel uhd and radeon 530 with seemingly no support for OpenCL, at least F@H-wise, but then the cpu is still of some use.
As this is an issue, the expectation is a slight readme update.
Yes, there are few CPU COVID-19 projects too

Cool. Added a ENV switch to my docker image. Should show in a couple of minutes.
see: https://hub.docker.com/r/amalic/nvdocker-folding-home
The radeon 530 GPU has OpenCL support and should be supported by Folding@Home.
Maybe reinstall the display drivers from AMD's website?

I indeed managed to install amd pro drivers for opencl, and blacktable RAW photo editor makes use of these extensions (both my intel uhd and radeon cards). clinfo also show the card since the drivers were installed.
Anyway, Radeon 350 (Iceland) is a mobile graphics card, and I noticed a 10-20% improvement when benching it against cpu in blacktable-cli (https://math.dartmouth.edu/~sarunas/darktable_bench.html - here the improvements are huge), so nothing drastic. So I guess it's not whitelisted, at least as far as I googled ;)
EDIT - that was premature<gpu v='false'/> seems to make ignore GPUs altogether, changing the value to true fixed it.
This might get offtopic, but actually, running FAHClient as my own user I did get my radeon recognised (more or less properly):

I just wonder what is missing to be working as use fahclient:
~ $ groups
piotr adm tty uucp dialout cdrom sudo audio dip video plugdev lpadmin sambashare vboxusers docker render
~ $ groups fahclient
fahclient : nogroup video render
Hi folks! We're getting a huge influx of interest, and we need to keep this issue tracker clear for scientific discussions among labs working on COVID-19 targeting, so I've just added new info on where to submit questions/issues like this. Could you migrate the discussion there?
Thanks so much for understanding, and thanks for helping us out!
