Subject: [OMPI users] OpenMPI with Gemini Interconnect
From: Saliya Ekanayake (esaliya_at_[hidden])

Hi,

We have a Cray XE6/XK7 supercomputer (BigRed II) and I was trying to get
OpenMPI Java binding working on it. I couldn't find a way to utilize its
Gemini interconnect, instead was running on TCP, which is inefficient.

I see some work has been done along these lines in [1] and wonder if you
could give some suggestions on how to build OpenMPI with Gemini support.

Thank you,
Saliya
