[gmx-users] How to tune number of CPUs for a run?

2009-11-04 Thread Pablo Englebienne
Hi all, I'm having some trouble running simulations with increasing number of CPUs. What parameters should I modify to make sure that the simulation would run with a specific number of processors? Or, having access to a large number of processors, how to select the number of CPUs to request?
