I have open-mpi 4.0.4 installed on my desktop and my small test programs are working.
I would like to migrate the open-mpi to a cluster and run a larger program there. When moved, the open-mpi installation is in a different pathname than it was on my desktop and it doesn't seem to work any longer. I can make the libraries visible via LD_LIBRARY_PATH but this seems insufficient. Is there an environment variable which can be used to tell the open-mpi where it is installed? Is it mandatory to actually compile the release in the ultimate destination on each system where it will be used? Thanks. .. Lana (lana.de...@gmail.com)
