Hi All,
FYI, we had trouble with Intel MPI in the past. A full install of their
compiler builds it along with the compiler. Users were having the compiler
paths, libs etc put in front, along with system dirs. So the OpenMPI module
sometimes was not seen even when it was just loaded. The patch was to force
the compiler "to the back of the line." The fix was we split the Intel
compiler into two modules. To get all their other toys beyond just the
compiler, you now have to load a second module. I don't know if this applies
in this case, but I thought I would toss it out in case someone else runs into
it.

Luis, it is perfectly possible to use different MPI on the same cluster.
May we ask what your OS and cluster management stack is?
Normally you use the Modules system to configure your job to use a chosen MPI

Err...the whole point of a container is to put all the library dependencies
_inside_ it. So why don't you just install OMPI in your singularity image?

Hello all,
I have Intel MPI in my cluster but I am running singularity image of a software
which uses OpenMPI.
Since they may not be compatible and I dont think it is possible to get these
two different MPI running in the system.
I wounder if there is some work arround for this issue.
Any insight would be welcome.
Luis
