[gmx-users] Segmentation fault in Gromacs parallel run

[Ge Sunny]

Hi,

I have a problem in running Gromacs in parallel. My simulation can be 
successfully run on 1 cpu. However, when running in parallel on more than 
one cpu (e.g., 4 cpus), there always occurs a Segmentation fault error:

ERROR: 0031-250  task 1: Segmentation fault

I'm running parallel Gromacs on an IBM AIX system using LoadLeveler to 
submit a "mdrun" job.

Does anybody have any idea about the problem?

Thanks,

George
