[OMPI users] MPI_Barrier in Self-checkpointing call

2012-02-15 Thread Faisal Shahzad
Dear Group, I wanted to do a synchronization check with 'MPI_Barrier(MPI_COMM_WORLD)' in 'opal_crs_self_user_checkpoint(char **restart_cmd)' call. Although every process is present in this call, it fails to synchronize. Is there any reason why cant we use barrier?Thanks in advance. Kind regards

code, problem is not too severe, so i used 48 or even 96 processes and many checkpoints to make problem appear. But i my actual code, perhaps due to more MPI calls, sometimes problem occur even within one node with only few (2-5) processes as well. Hope to hear from you.Kind regards,Faisal Shahza
