Some platforms do not support shared memory, they will create a SHM communicator which essentially equals to comm_self. This test should not be executed on such platforms. Thus we check the number of processes in SHM communicator and exit if only one process exists. Signed-off-by: Xin Zhao <[email protected]> Signed-off-by: Antonio J.
