[gmx-users] GROMACS Parallel Runs

[Sunny]

Hi,

I am using GROMACS 3.3.1 parallel runs on an AIX supercomputing system. My 
simulation can successfully run on 16 and 32 CPUs (as well as below 16 
CPUs). When running on 64 CPUs, however, segmentation fault occurs in 
multiple tasks from very beginning of the simulation. I'd like know what 
causes the failure and whether there is any solution to fix the failure.

Thanks,

Sunny
