[gmx-users] GPU performance

[Mark Abraham]

Running mdrun and anything else sharing the same hardware requires explicit
management so that they do not actually share CPU cores. mdrun is designed
to saturate the cores, and dramatic nonlinear degradation is exactly what
should be expected from sharing any core.

But rather than speculate, how about looking at the log file for the
performance reports and seeing what is actually different?
