I am having some trouble running NAMD 2.10 for Linux-x86_64-MPI-smp-CUDA. I am running on 128 processors, 128 nodes, and 8 physical nodes. The warning I am getting at the beginning is as follows:
Charm++> Warning: the number of SMP threads (32) is greater than the number of physical cores (16), so threads will sleep while idling. Use +CmiSpinOnIdle or +CmiSleepOnIdle to control this directly.
I am not sure how to address this issue, and it seems to take a long time for "startup phase 1" to run compared to the other startup phases. Has anyone else had similar problems?
