WebBy default Open MPI will choose a binding based on the used mapping, e.g., if you map processes by socket they will be bound by socket. If you want to specify the process binding explicitly you can use the --bind-to option. For example, mapping processes by socket but binding them to cores (instead of the socket default) can be done with Webby --map-by :PE=N. I've tried this but I couldn't get the expected allocation of procs. For example I was running 2 procs on 2 nodes each with 2 sockets where a socket has 4 cores. I wanted 1 proc per node and bound to all cores in one of the sockets. I could get this by using --bind-to core: --map-by ppr:1:node --cpus-per-proc 4 -np 2

However with ppr, slots are not taken into account other than the requirement that enough slots exist to satisfy the specified processes per resourceinstruction. high tea marenland
