[mpich-discuss] Error in MPI_PROBE

[Rajeev Thakur]

Make sure you are compiling the program with the mpicc from MPICH2 1.4.1, not some other mpicc by mistake. Give the full path if necessary. Likewise for mpiexec.

> a) Line 1 says that the communicator is invalid but at line 2 it is possible to see that the MPI_PROBE function recognized that the communicator is MPI_COMM_WORLD. In which conditions this can happen?
> b) What is the meaning of the numbers right after the mpi functions names that appear inside the parenthesis on error messages (MPI_Probe(113) for example)?
