[mvapich-discuss] osu benchmarks over tcp

[Devendar Bureddy]

Hi Hoot

Thanks for using OSU benchmarks.  This issue is not with benchmarks.
It seems, you are using OpenMPI library. You can check this issue in
openMPI mailing list.

You can also configure MVAPICH2 in TCP/IP  mode to test over a 10GigE.
 Please take a look at the following sections in mvapich2 user guide
for this.
http://mvapich.cse.ohio-state.edu/support/user_guide_mvapich2-1.7rc1.html#x1-180004.9
http://mvapich.cse.ohio-state.edu/support/user_guide_mvapich2-1.7rc1.html#x1-190004.10

Please let us know if you see any issues with MVAPICH2.
