All, I was not expecting things to work, and find that codes compiled using OpenMPI 1.4.1 commands under SLES 10.2 produce the following message when run under SLES11:
mca: base: component_find: unable to open /share/apps/openmpi-intel/1.4.1/lib/openmpi/mca_btl_openib: perhaps a missing symbol, or compiled for a different version of Open MPI? (ignored) This file is in position and is NOT the result of a faulty mixed-release over-build (things work great under SLES10.2). The message indicates that (as the default is to build OpenMPI dynamically with share objects) in loading this required IB-related library there must be a format incompatibility. However, I find that if I force the use of GE with: -mca btl tcp,self things seem to run OK under SLES 11. Could someone add some detail here on what, if anything, I can expect to work when we try to run old SLES 10.2 build OpenMPI 1.4.1 binaries under SLES 11. I would have thought NOTHING, but maybe that is not quite right. Perhaps we can run using GE under SLES 11 with the old binaries until I get things recompiled (ugh!) under SLES 11?
