Yes; that's what I was thinking, but wanted to get the data point first. Specifically: if this test works (i.e., commenting out the de/registration avoids the slowdown), there's at least two things we devs should consider: 1. Disable the entire de/registration code path for ALLOC/FREE_MEM (e.g., perhaps the lazy method is just better, anyway). 2. Provide an MCA param to disable the de/registration code path for ALLOC/FREE_MEM. Let's see how the test goes. -- Jeff Squyres jsquy...@cisco.com _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
