HI Ben, Even on one box, the yoda component doesn't work any more.
If you want to do OpenSHMEM programming on you Macbook pro (like I do) and you don't want to set up a VM to use UCX, then you can use Sandia OpenSHMEM implementation. https://github.com/Sandia-OpenSHMEM/SOS You will need to install the MPICH hydra launcher http://www.mpich.org/downloads/versions/ as the SOS needs that for its oshrun launcher. I use hydra-3.2 on my mac with SOS. You will also need to install OFI libfabric: https://github.com/ofiwg/libfabric I'd suggest installing the OFI 1.5.1 tarball. OFI is also available via brew but its so old that I doubt it will work with recent versions of SOS. If you'd like to use UCX, you'll need to install it and Open MPI on a VM running a linux distro.
