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? On Oct 14, 2013, at 11:00 AM, Ray Sheppard wrote: > Thanks Ralph, Thanks Jeff, > I should have written sooner. I spent the weekend trying to set it as a > configure option. > Ray > > > On 10/14/2013 10:

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. On Oct 14, 2013,
