mpirun -np 2 ompi_info | head Or something like that. With 1.10, I don't know/remember the mpirun CLI option to make one process per node (when ppn>1); you may have to check that. Or just "mpirun -np 33 ompi_info | head" and examine the output carefully to find the 33rd output and see if it's different. That being said, thinking a little deeper on this: with your ld output, it's probably kinda unlikely that you have mismatched versions (because you're linking against very specific OMPI library versions) -- particularly if you're getting the same error when running on a single node. Open MPI is 100% user space code -- you can just install Open MPI v4.0.2 under your $HOME and run it there. You might want to see how your system-level Open MPI is installed (e.g., use the right ./configure option to get the PBS/TM integration, if you have a high-speed/HPC-class network support API library, ...etc.), and mimic all of that in your own personal Open MPI install. -- Jeff Squyres jsquy...@cisco.com
