Dear Gilles, Dear all, I have found the error. Some CPU has no element to share. It was a my error.
Now I have another one: *Fatal error in MPI_Isend: Invalid communicator, error stack:* *MPI_Isend(158): MPI_Isend(buf=0x137b7b4, count=1, INVALID DATATYPE, dest=0, tag=0, comm=0x0, request=0x7fffe8726fc0) failed* In this case with MPI does not work, with openMPI it works. Could you see some particular information from the error message?
