[OMPI devel] Setting AUTOMAKE_JOBS

Some of you may be unaware that recent versions of automake can run in parallel. That is, automake will run in parallel with a degree of (at most) $AUTOMAKE_JOBS. This can speed up the execution time of autogen.pl quite a bit on some platforms. On my cluster at cisco, here's a few quick

[hwloc-devel] roadmap

Hello, hwloc 1.0 was released in May. I think we should release 1.1 before SC10, which means doing a first RC within a couple weeks. trunk got many changes since 1.0, but nothing very important. trac says we're missing memory binding, distances and user-defined process restrictions. Memory
