Hi all,

I am running a MPI program on two machines. I got errors as follows:


====================================================================
Fatal error in MPI_Test: Other MPI error, error stack:

====================================================================


I have never seen such errors before. What is the cause of this error? Is it an out of memory error? ( There is 20% remaining memory on machines )

Any help would be greatly appreciated. Thanks in advance!
