Hi Brice, lots of useful features!
I would like to check if there is a plan to include in 1.8 proposed feature for hwloc-distrib to start distribution from the last object. For the reference please see my e-mail from Wed, Sep 18, 2013 with the Subject Patch file to let hwloc-distrib output the PUs starting from the last object I would really appreciate if you can include it into the 1.8 version. Thanks a lot!
