Dear Users,
I have a 64-core node with 4 GPUs and I am running MD on an 80K system.
Is there a good combination of CPUs+GPUs that gives best performance in
terms
of ns/day? I want to learn from your experience.
With the following command:
namd2 +idlepoll +p16 +devices 0 eq02.conf >& eq02.log
I could get 0.4days/ns and I don't know if I can improve on it, as adding
more GPUs or CPUs
didn't help.
Also, I am not sure if I am missing any command line options that might
help with a performance boost.
Thanks,
Ravi
