Folding Slot count limit
Posted: Tue Apr 14, 2020 12:27 pm
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:
Snippet about GPU load
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?
