I pushed big changes to the components in the last days (what came from last month discussion + recent CPUModel feature requests).
Now we ombine information from multiple "cpu" backends. For instance the x86 backend will add socket CPUModel to what native OS backends did. Aside from xml/synthetic/custom excluding everything else, other backends let others try to complete the topology if they have something to add/annotate. Only component management has changed. Their "pluginification" is still the same as earlier. Old "core" components are now called "disc" for discovery (that's all they do, binding doesn't need to be componentified). Instead of describing everything, here are pointers to the new documentation: https://svn.open-mpi.org/trac/hwloc/browser/branches/components/doc/hwloc.doxy Lines 1635-1725 for how it works from the user side Lines 974-1011 for environment variables The components branch has a ugly SVN history now. Hopefully SVN will combine all that history into one single commit and nobody will see the ugly components history (except people using git-svn maybe). Brice
