Hi,
I have a question concerning running NAMD on a CUDA cluster.
NCSA Forge has for example 6 CUDA devices and 16 CPU cores per node. If I
want to use all 6 CUDA devices in a node, how many processes is it
recommended to spawn? Do I need to specify "+devices"?
So, if for example I want to spawn 12 processes, do I need to specify:
charmrun +p12 -machinefile $PBS_NODEFILE +devices 0,1,2,3,4,5 namd2
+idlepoll
Thanks,
Gianluca
