Hello
I'm trying to use MPI_COMM_TYPE_SHARED with MPI_Comm_split_type.
Everything works fine with mpich 3.1.4 (ie. on two 20 cores nodes, the size
of each shared communicator is 20);
However, it doesn't work with mvapich (version 2.1a, because my application
use Mpi_comm_spawn and this doesn't work in 2.1rc1): My shared communicator
size is only one.
Is it supported by mvapich ?
