[mvapich-discuss] MV2_IBA_HCA variable

[Hari Subramoni]

Hi Mahesh,

Your understanding of the parameter is correct. The version of MVAPICH2 you
are using is several years old. We would recommend that you upgrade to the
latest version MVAPICH2-1.9a2 or MVAPICH2-1.8.1 to take advantage of this
feature. Please let us know if you face any issues with the newer version
of the library.

Thanks,
Hari.
