[mvapich-discuss] mvapich support of MPI_connect and MPI_accept

[Hari Subramoni]

Can you please try to run with mpirun_rsh? DPM is only supported with
mpirun_rsh for now.

mpirun_rsh -np <num_procs> -hostfile <path_to_hostfile> MV2_SUPPORT_DPM=1
<binary>.

Thx,
Hari.

Thank you.

i tried to do

mpiexec -genv MV2_SUPPORT_DPM 1
and cannot even get past initialization now.

WARNING: Error in initializing MVAPICH2 ptmalloc library.Continuing without
InfiniBand registration cache support.
[cli_0]: aborting job:
Fatal error in MPI_Init:
Other MPI error, error stack:
MPIR_Init_thread(514)...:
MPID_Init(365)..........: channel initialization failed
MPIDI_CH3_Init(356).....:
MPIDI_CH3I_CM_Init(1748):
MPICM_Init_UD_CM(2098)..: Couldn't allocate MR

Either i do not understand the invocation CLI or there's something else. I
do want to use IB support of course.
