Perhaps Nathan can comment on the status of the native Gemini work in Open
MPI...

Hi Jeff,
On the Cray are two modes. ESM is the preferred method but some
packages require the CCM (cluster compatibility mode). In ESM, MPI is
transparent and works great. In CCM, an external MPI is needed. There
is supposed to a translator to make the Gemini switch look like IB, but
it do
Just curious -- why are you using the TCP transport on a Cray?

Thanks Ralph, Thanks Jeff,
I should have written sooner. I spent the weekend trying to set it as
a configure option.

It won't be a configure switch, but you can put the following in your default
system mca param file:
btl_tcp_if_include=ipogif0
You'll find that file in /etc - it is called openmpi-mca-params.conf.
Users won't have to enter it after that since we pick that file up by default.
