[mvapich-discuss] Support of FCA and MXM (HPCSx toolkit) from Mellanox

[Panda, Dhabaleswar]

Hi Michael,

Many of the features of MXM and FCA (such as UD, hybrid UD+RC/XRC, optimized
collectives, etc.) are already available in MVAPICH2. Please take a look at the
MVAPICH2 user guide about how to activate and use these features.

Thanks,

DK

Hello,

I was wondering if MVAPICH 2.1 (or MVAPICH1.9) are taking advantage of the "accelerator" S/W from Mellanox that come with the HPC-X toolkit (MXM and FCA). I assume this has to be enabled during ./configure, correct?

Can we see tangible performance improvements with MVAPICH2 leveraging HPC-X?

Thank you
Michael
