[mvapich-discuss] MPI SPAWN with MVAPICH2

Thu May 28 05:38:37 EDT 2009

Hi!

I have a small test that uses the MPI_COMM_SPAWN_MULTIPLE function.

When I run it, it gives me this error:

MPI_Comm_spawn_multiple(152)..: MPI_Comm_spawn_multiple(count=1,
cmds=0x7fffae068470, argvs=0x7fffae068430, maxprocs=0x7fffae068450,
infos=0x7fffae068410, root=0, MPI_COMM_WORLD, intercomm=0x7fffae068614,
errors=0x7fffae0683f0) failed
MPID_Comm_spawn_multiple(67)..:
MPIDI_Comm_spawn_multiple(172):
MPID_Open_port(69)............: Function not implemented

It seems that that function is not implemented in MVAPICH-2, is it true?
But MPI_Comm_spawn_multiple is a standard MPI2 function.

I use mvapich2-1.2p1.

Thank you!
