While I have yet to get a working build on NetBSD for x86-64 h/w, I *have* successfully built Open MPI's current 1.7.4rc tarball on NetBSD-6 for x86. However, I can't *run* anything:
Attempting the ring_c example on 2 cores: -bash-4.2$ mpirun -mca btl sm,self -np 2 examples/ring_c -------------------------------------------------------------------------- While computing bindings, we found no available cpus on the following node: Node: pcp-j-17 Please check your allocation. -------------------------------------------------------------------------- The failure is the same w/o "-mca btl sm,self" Singleton runs fail just as the np=2 run did. I've attached compressed output from "ompi_info --all". Since this is probably an hwloc-related issue, I also build hwloc-1.7.2 from pristine sources. I have attached compressed output of lstopo which NOTABLY indicates a failure to bind to both of the CPUs. For now, an explicit "--bind-to none" is working for me. Please let me know what additional info may be required. -Paul -- Paul H.
