Unfortunately, I can't reproduce. I tried with your tarball, with a Redhat 5 machine, with a similar Nehalem-based machine running Debian. Can you try to debug this? I'd like to know if EINVAL is returned by the kernel or by hwloc. You'd have to open src/topology-linux.c, go in function hwloc_linux_get_thisthread_membind() and add some printf there to check where EINVAL comes from. thanks, Brice
