Folding Slot count limit

[blizko]

Greetings,

Have been trying to set up Folding at home on a multi-GPU compute node (total of 12 GPUs) and have noticed that FAHClient is not loading more that 10 GPUs simultaneously. For more that a week of observations - last 2 GPUs are always idle
Snippet of the config file:

Code: Select all

  <!-- Folding Slots -->
  <slot id='0' type='GPU'/>
  <slot id='1' type='GPU'/>
  <slot id='2' type='GPU'/>
  <slot id='3' type='GPU'/>
  <slot id='4' type='GPU'/>
  <slot id='5' type='GPU'/>
  <slot id='6' type='GPU'/>
  <slot id='7' type='GPU'/>
  <slot id='8' type='GPU'/>
  <slot id='9' type='GPU'/>
  <slot id='10' type='GPU'/>
  <slot id='11' type='GPU'/>

Snippet about GPU load

Code: Select all

/sys/kernel/debug/dri/0/amdgpu_pm_info:GPU Load: 95 %
/sys/kernel/debug/dri/1/amdgpu_pm_info:GPU Load: 100 %
/sys/kernel/debug/dri/2/amdgpu_pm_info:GPU Load: 21 %
/sys/kernel/debug/dri/3/amdgpu_pm_info:GPU Load: 68 %
/sys/kernel/debug/dri/4/amdgpu_pm_info:GPU Load: 86 %
/sys/kernel/debug/dri/5/amdgpu_pm_info:GPU Load: 0 %
/sys/kernel/debug/dri/6/amdgpu_pm_info:GPU Load: 98 %
/sys/kernel/debug/dri/7/amdgpu_pm_info:GPU Load: 50 %
/sys/kernel/debug/dri/8/amdgpu_pm_info:GPU Load: 80 %
/sys/kernel/debug/dri/9/amdgpu_pm_info:GPU Load: 46 %
/sys/kernel/debug/dri/10/amdgpu_pm_info:GPU Load: 0 %
/sys/kernel/debug/dri/11/amdgpu_pm_info:GPU Load: 0 %

Other applications do utilize all of the available GPUs

Is there any limitation for the maximum possible slot count? Or any specific options necessary for more than 10 slots?

This is a known limitation of the client, there is an existing problem report on GitHub for this. The current maximum is 10, the single digits from 0 to 9.
