I and new to OpenMPI and have looked for this, but not getting anywhere.
I got an example program off this site:
The compute PI in Fortran example.
http://www.mcs.anl.gov/research/projects/mpi/usingmpi/examples/simplempi/main.htm
Compiled it with "mpif90" and no errors.Then used the qsub -I and tried both
executing directly and "mpirun" and still receive these errors:
[MGT-2-1:02994] *** An error occurred in MPI_Comm_rank[MGT-2-1:02994] *** on
communicator MPI_COMM_WORLD[MGT-2-1:02994] *** MPI_ERR_COMM: invalid
communicator[MGT-2-1:02994] *** MPI_ERRORS_ARE_FATAL (goodbye)
Any guidance in the right direction would be appreciated.
Thanks
Trent
