Hi! I have a little code that uses the MPI_Comm_spawn_multiple, I've used it without any problems with the MPICH2 and MVAPICH2 implementation of MPI-2, but with the Open MPI v1.3.3 it throws this error:
*** An error occurred in MPI_Comm_spawn_multiple *** on communicator MPI_COMM_WORLD *** MPI_ERR_INFO: invalid info object *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort) and I've seen on http://www.mpi-forum.org/docs/mpi21-report-bw/node204.htm#Node204 that the MPI_Info object keys depend on the implementation. Does the OpenMPI have a different implementation in respect of the MPICH/MVAPICH? What I have to change in order to make it run? Or the problem is elsewhere located? Thank you very much, Federico Golfrè Andreasi
