We have an issue with binding to cores with some applications and the default causes issues. We would, therefore, like to set the equivalent of mpirun --bind-to none globally. I tried search for combinations of 'openmpi global settings', 'site settings', and the like on the web and ended up sev

For the 1.10 series, putting "export OMPI_MCA_hwloc_base_binding_policy=none” into your default MCA param file will solve the problem. I believe that is true for all of the 1.8 series as well, and suspect the man page for 1.8.2 was simply out-of-date. You could verify that if you are using some

I tried replacing the MPI_Alloc_mem/MPI_Win_create pair with MPI_Win_allocate but it doesn't seem to have much of an effect. It may improve the overall success rate in some cases but overall, it seems a wash. I haven't done any timing, I've mostly been focusing on correctness, so I don't know if
