[mvapich-discuss] SDP run stuck with Nemesis

[Eva Mishra]

we are running IMB benchmark with MVAPICH2-1.9 - (TCP/IP build for
Nemesis) over InfiniBand 20Gbps network

we are observing IMB runs with SDP get stuck in Reduce_scatter benchmark.
This observation is true only for Nemesis channel. For CH3 channel, all
benchmarks are through successfully.

What can be done to resolve this problem?


Regards,
Eva
