The Java bindings are written on top of the C bindings, so you'll be able
to use those networks just fine from Java :-)

Thank you Nathan, this is what I was looking for. I'll try to build OpenMPI
1.8 and get back to this thread if I run into issues.

You do not need CCM to use Open MPI on with Gemini and Aries. Open MPI
has natively supported both networks since 1.7.0. Please take a look at
the platform files in contrib/platform/lanl/cray_xe6 for CLE 4.1
support. You should be able to just build using:
configure --with-platform=contrib/platfor
I see. Also, I wanted to build OpenMPI because the provided OpenMPI didn't
have Java binding. It seems at this point the only option is to use TCP in
CCM in BigRed 2 and if I remember correctly Mason and Quarry don't have IB
as well, correct?
Thank you,

Hello,
Big Red 2 provides its own MPICH based MPI. The only case where the
provided OpenMPI module becomes relevant is when you create a CCMLogin
instance in Cluster Compatibility Mode (CCM). For most practical uses,
those sorts of needs are better addressed on the Quarry or Mason machines.
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
