Jeff Squyres 50e5b0937c Add hwloc 1.3.1, but it is not yet the default -- it is currently .ompi_ignored to allow other developers to test with it. It is expected that we'll remove the .ompi_ignore here soon, and simultaneously remove the hwloc 1.2.2ompi component. There was one very minor patch added to stock hwloc 1.3.1 in hwloc/config/hwloc.m4: {{{ --- hwloc-1.3.1/config/hwloc.m4 2011-12-14 +++ ompi3/opal/mca/hwloc/hwloc131/hwloc/config/hwloc.m4 @@ -583,6 +583,7 @@ ]) fi AC_SUBST(HWLOC_PCI_LIBS) + HWLOC_LIBS="$HWLOC_LIBS $HWLOC_PCI_LIBS" # If we asked for pci support but couldn't deliver, fail AS_IF([test "$enable_pci" = "yes" -a "$hwloc_pci_happy" = "no"], [AC_MSG_WARN([Specified --enable-pci switch, but could not]) }}} This will be pushed upstream to hwloc.

Makefile.am	Per the RFC from Jeff, move hwloc from opal/mca/common to its own static framework ala libevent.

The HNP only retains unique topology "templates" to reduce memory footprint. Have the daemon include the local topology info in the nidmap buffer sent to each app so the apps don't all hammer the local system to discover it for themselves.	2011-09-11 19:02:24 +00:00

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: OMPI_CONFIG_SUBDIR (instead of slurping in hwloc's
   .m4 files).
