Yes, use the --from socket of hwloc-distrib (previously called --among socket). > This is not working. So I have tried various --among and -ignore options to > achieve this but without success. --among socket is what should be working (renamed to --from after rc2), at least it does work for me: $ ./utils/hwloc-distrib --input /tmp/hp-dl980g7-01 --from socket 8 0x000000ff,,0x000000ff 0x00ff0000,,0x00ff0000 0xff000000,,0xff000000 0x000000ff,,0x000000ff,0x0 0x0000ff00,,0x0000ff00,0x0 0x00ff0000,,0x00ff0000,0x0 0xff000000,,0xff000000,0x0 0x0000ff00,,0x0000ff00 Isn't this what you want? (with additional --single of course) Actually, I'm considering to just implement unbalanced distribution support for v1.1, it shouldn't be too hard. Samuel
