Subject: Re: [OMPI users] Passing LD_LIBRARY_PATH to orted
From: George Bosilca (bosilca_at_[hidden])

This is a problem with the Intel libraries and not the Open MPI ones.
You have to somehow make these libraries available on the compute nodes.

What I usually do (but it's not the best way to solve this problem) is
to copy these libraries somewhere on my home area and to add the
directory to my LD_LIBRARY_PATH.
