Hi Brice, I have found couple of issues with 1.1rc2
1) man hwloc-bind Following example does not work: $ hwloc-bind --cpubind node:1 --membind:0 echo hello Unrecognized option: --membind:0 2) hwloc-bind --get --membind is not working for me (RHEL 6.0) $ hwloc-bind --membind node:1 --mempolicy interleave -- hwloc-bind --get -- membind hwloc_get_membind failed (errno 22 Invalid argument) 3) $ hwloc-calc --single socket:0 Unrecognized option: --single It seems like the old option --proclist still works. $ hwloc-calc --proclist socket:0 0,1,2,3,4,5,6,7 hwloc --help is mentioning only --single option.
