Nathan Hjelm 899bf548a2 opal/hwloc: fix topology detection when socket is above numa The OPAL_PROC_ON_* definitions have been changed from values to flags. This should not cause any problems as these values were already used as flags throughout the code base. Note, there will be a difference between localities produced by the new code and the old. For example, if a machine does not have a level-3 but two cores share a level-1 or level-2 cache cache the level-3 bit will not be set in the locality and OPAL_PROC_ON_LOCAL_L3CACHE will return 0. Before this change it would have returned 1. In addition the OPAL_PROC_ON_LOCAL_* macros have been simplified. Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>		2015-09-10 14:17:45 -06:00

Notes for hwloc component maintainers:

1. There can only be *1* hwloc version component at a time.
   Specifically: if there are multiple hwlocXYZ components (i.e.,
   different versions of hwloc), then they must all be .ompi_ignore'd
   except for 1.  This is because we currently m4_include all of the
   underlying hwloc's .m4 files -- if there are multiple hwlocXYZ
   components, I don't know if m4 will barf at the multiple,
   conflicting AC_DEFUNs, or whether it'll just do something
   completely undefined.

1a. As a consequence, if you're adding a new hwloc version component,
   you'll need to .ompi_ignore all others while you're testing the new
   one.

2. If someone wants to fix #1 someday, we might be able to do what we
   do for libevent: OPAL_CONFIG_SUBDIR (instead of slurping in hwloc's
   .m4 files).
