[mvapich-discuss] MPI Code hangs at MPI_Init

[Vaibhav Sundriyal]

Hi,


I have configure MVAPICH on two nodes and when I give the command

mpirun -n 2  -hostfile hostfile -env MV2_SMP_USE_CMA=0 hostname

where hostfile looks like

node1:1
node2:2

, the hostnames of both the nodes get printed. But, when I try to execute
OSU benchmark ./osu_latency, the execution hangs. Through some debugging, I
figured out that the execution hangs at

MPI_CHECK(MPI_Init(&argc, &argv));

Can anyone help me resolve this issue?

Thanks.
