This is pretty much the standard installation procedure. What we also need
know are the compilers used, etc. for the installation. The error you're
getting is from MPICH. Which version is installed on the cluster? It may
old and buggy. In any case, you can try to install something newer, like a
recent version of OpenMPI (which we have on our cluster); it may be more
reliable. Only a random thought, means nothing unless we know what you have
What about the contents of your system, as I asked before? Do you really
100% virtual site system?
