Hello all There is a known issue on master that we are attempting to debug. Sadly, it is one that only shows on multi-node operations, and the signature varies based on your environment. We hope to have this resolved soon (and no, it doesn’t appear to be due to any one specific commit).
In the interim, setting the MCA param routed=direct appears to provide a workaround - at least, it is working for me, and hopefully will work for you too Ralph _______________________________________________ devel mailing list devel@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/devel
