Once that's done, associate a secondary hostname with the secondary IP (/etc/hosts).
Then just use the secondary or primary hostnames (whichever one doesn't conflict with the traffic you're avoiding) in your MPI machinefile.
One day in the future we may have the second interface auto-configured, but we're not there yet.
good luck-

hi
I am working on a linux cluster (10 nodes) at TIFR. I am using OSCAR v2.2, and RH linux 7.2. Each of my nodes has 2 n/w cards. One of them is used by oscar to communicate with the other nodes. I want that MPI should use the other n/w card, so that MPI communications take place independent of the other n/w traffic. Is such a thing feasible ? If yes which config files should I edit ?
regards, Aalap
