I am running GROMACS 4.6.2 on a GPU cluster in our reasearch group. I am trying
to bench mark some systems, and I am getting this message:
NOTE: The number of threads is not equal to the number of (logical) cores
and the -pin option is set to auto: will not pin thread to cores.
This can lead to significant performance degradation.
Consider using -pin on (and -pinoffset in case you run multiple jobs).
Each node has 2 GTX 580s and 4 physical cores. So when I submit a job I set -nt
2. But since we have a queuing system, there is no way to know which cores will
be available to set -pinoffset. Does anyone have a solution, or should I even
be worrying about that at all?
Thanks,
Tim--
