[gmx-users] mpi error

[Ragothaman Yennamalli]

Dear all,
I had been running many runs of mdrun in a Sun opteron
cluster with each node having 4 processors.
When I ran my latest mdrun after 15ns run, I get the
following error and mdrun exits without any error
message on other log files. 
*******************************************************

Please tell me how to troubleshoot this problem as it 
repeated when ran again.

Waiting for your reply,
