Jeff Squyres b8af3b7c4a New comment explains it all -- previous code was failing to find the
Nth core, so it fell over to try to find the Nth PU.

-----

hwloc isn't able to find cores on all platforms.  Example: PPC64
running RHEL 5.4 (linux kernel 2.6.18) only reports NUMA nodes and
PU's.  Fine.

However, note that hwloc_get_obj_by_type() will return NULL in 2
(effectively) different cases:

- no objects of the requested type were found
- the Nth object of the requested type was not found

So first we have to see if we can find *any* cores by looking for the
0th core.  If we find it, then try to find the Nth core.  Otherwise,
try to find the Nth PU.

test WARNING: Work on the temp branch being merged here encountered problems with bugs in subversion. Considerable effort has gone into validating the branch. However, not all conditions can be checked, so users are cautioned that it may be advisable to not update from the trunk for a few days to allow MTT to identify platform-specific issues. 2010-09-17 23:04:06 +00:00
Makefile.am Fix mistake that came in via the ompi-agen tree in r23764. The mistake wasn't part of the core autogen upgrade; it was an additional 'bonus' cleanup. Oops. The mistake will always create a set of directories under installdir, even if you do not --with-devel-headers. The set of directories will be empty, but still -- they should not be there at all. This commit fixes that -- the directories are not created at all if you do not --with-devel-headers 2010-09-24 22:53:28 +00:00
