You should be able to run whatever version of open-mpi you want. You just need to make sure that in the build and run steps that you don't mix the two. I have had good results using modules (you can google it, download it, build and install it) to keep them separate. You probably want to upgrade to gcc 3.x.x or 4.x.x and use module for that also).

On our cluster we have RedHat Linux 7.3 Professional, and on the cluster specification it says the following:
-The cluster should be able to run the follwoing software tools:
    • gcc 2.96.x(or 2.95.x or 2.91.66)
    • Bison 1.28
    • flex 2.5.4
    • mpich 1.2.5

So i am just wondering if my cluster is capable to run openmpi 1.2.7?? I haven't contacted the cluster technicians yet but i just wanted to know your answer first. Many thanks in advance.
