This might mean that you have some kind of issue with your local compiler. FWIW, on my MacOS laptop, "which objdump" finds /usr/bin/objdump, not /Applications/Xcode.app/...etc. Can you send the stdout/stderr from running configure, and the config.log file? -- Jeff Squyres jsquy...@cisco.com

Make sure that PSM > works on the system. Then make sure you got a mca_mtl_psm built. I think Peter is right: you want to use mpirun --mca pml cm --mca mtl psm ... I *think* Intel InfiniPath is PSM and Intel OmniPath is PSM2, so "psm" is what you want (not "psm2"). Don't try to use pml/ob1 + btl/openib, and don't try to use UCX. PSM is Intel's native support for its Infinipath network. -- Jeff Squyres jsquy...@cisco.com
