Hello,
We have a workstation with 12 CPU's and 4 GPU's and we are trying to run
NAMD simulations in it, but we are not sure we are actually using the GPU's.
Here is the first part of a log file using the workstation.
Charm++> scheduler running in netpoll mode.
Charm++> Running on 1 unique compute nodes (12-way SMP).
Charm++> cpu topology info is gathered in 0.007 seconds.

Which is the correct command to run the NAMD in the workstation?
We are currently using one similar to this:
charmrun ++local +p4 namd2 +idlepoll [configuration file] > [log file]
Thanks for your time!
