[mvapich-discuss] Multirail scripts of mvahpich-0.9.9-beta2

[Abhinav Vishnu]

Hi Egor,

I forgot to mention in the previous mail that MVAPICH2 has an integrated
multi-rail device (multiple ports, Adapters and QPs), in addition it
supports many more features than MVAPICH multi-rail device. I would
strongly recommend you to use MVAPICH2 for your evaluation. For a
complete reference of MVAPICH2 features, please see the following link
to MVAPICH2 user guide:

http://nowlab.cse.ohio-state.edu/projects/mpi-iba/download-mvapich2/mvapich2_user_guide.html#x1-40003

The download, compilation and usage instructions are present at the
following URL:

http://nowlab.cse.ohio-state.edu/projects/mpi-iba/download-mvapich2/mvapich2_user_guide.html#x1-50004

Please let us know the outcome of your experimentation.

Thanks,
