FAHClient idle on highend systemg (eg. 128 cpu cores)

[dreamax]

Hi all,

I'm running the FAHClient on some highend Linux machines, eg.

Dual AMD Epyc 7742 (128 cores / 256 threads)
Dual Intel Xeon Platinum 8280 + 8x NVIDIA Titan RTX.

After about 3 hours of processing WUs all CPU cores and 2-3 GPUs are idle for more than 24 hours.

Log messages are always:

WARNING:WU04:FS08:Failed to get assignment from '65.254.110.245:8080': No WUs available for this configuration

Is this normal behavior? This way the operation doesn't make any sense to me.

Servers cannot yet deliver enough work units for the high demand.

As alternative you could run BOINC Rosetta Corona-Virus work units for CPUs and GPUgrid.net work units for GPUs

On the CPU side you may need to run multiple slots to partition the available CPU cores to get WU's, only some projects support large numbers of CPU threads.

Also when F@h got all the free publicity a week ago they were still in the process of creating projects for COVID-19. They were farther along on the GPU side, more projects are in the works of r CPU processing and should be out soon.

Welcome to Folding@Home!

If it was me and I had 256 cores to fold on I would divide them into 16 Slots of 16 threads each.
It is up to the researcher to specify how many CPUs their project can fold on, and I am unaware of any that allow 256 threads. (How would I know, my PCs have 4 threads?)

If that works try 8 of 32 threads, then 4 of 64 threads. At some point, I bet you quit getting work, just a lack of imagination of the part of the researchers.

Best of luck, more science is better science!

I think cpu jobs are just hard to find still at this point. My cpu has been 90% idle for the last week. I've tried 8,12,16 threads, still no jobs. GPUs have been folding non-stop for a few days now though.

Yeah. The research teams are rapidly trying to get more projects and especially more COVID-19 projects into the queue to keep up with the overwhelming demand. I'm hoping the situation should clear up in the next couple of days.
