Re: [OMPI devel] coll/ml without hwloc (?)
Theoretically, we may make it functional (with good performance) even without hwloc. As it is today, I would suggest to disable ML if hwloc is disabled.

[OMPI devel] coll/ml without hwloc (?)
Folks, i just commited r32604 in order to fix compilation (pmix) when ompi is configured with --without-hwloc now, even a trivial hello world program issues the following output (which is a non fatal, and could even be reported as a warning) : [soleil][[32389,1],0][../../../../../../src/ompi-trunk/ompi/mca/coll/ml/coll_ml_module.c:1496:ml_discover_hierarchy] COLL-ML Error: (size of mca_bcol_base_components_in_use = 3) != (size of mca_sbgp_base_components_in_use = 2) or zero. [soleil][[32389,1],1][../../../../../../src/ompi-trunk/ompi/mca/coll/ml/coll_ml_module.c:1496:ml_discover_hierarchy] COLL-ML Error: (size of mca_bcol_base_components_in_use = 3) != (size of mca_sbgp_base_components_in_use = 2) or zero. in my understanding, coll/ml somehow relies on the topology information (reported by hwloc) so i am wondering whether we should simply *not* compile coll/ml or set its priority to zero if ompi is configured with --without-hwloc any thoughts ?
