[mvapich-discuss] How to configure MPD for using RDMA through Chelsio iWarp adapters

[Parav Pandit]

Hi Hari,

I am trying mpirun_rsh.

I ran (on 1.1 system-1)
../bin/mpirun_rsh -np 1 system-2 LD_LIBRARY_PATH=/usr/local/lib MV2_USE_IWARP_MODE=1 MV2_USE_SRQ=0 ./srtest

I get following output.

Process 0 on system-2
Process 0 of 1
0 sending 'hello there'

And it waits in MPI_Send().

I have basic question. Should I be running -np = 2 or 1? I believe one.
If I run just one process, what will run on compute node and what will run on front-node??

Any other example through which I can exercise the traffic, various iWarp verbs through mvapich2?

Regards,
Parav Pandit
