WHAT: Remove all non-hwloc paffinity components.
WHY: The hwloc component supports all those systems.
WHERE: opal/mca/paffinity/[^hwloc|base] directories
WHEN: for 1.5.1
TIMEOUT: Tuesday call, May 25 (yes, about 2 weeks from now -- let hwloc soak
for a while...)
-----------------------------------------------------------------------------
MORE DETAILS:
As you probably noticed, I have (finally) committed the "hwloc" paffinity
component to the trunk and removed the "linux" (i.e., PLPA) paffinity component:
https://svn.open-mpi.org/trac/ompi/changeset/23125
https://svn.open-mpi.org/trac/ompi/changeset/23126
hwloc supports all systems that OMPI supports (and several that OMPI doesn't!)
-- more specifically, it supports all the other systems that we have paffinity
components for (darwin, linux, posix, solaris, windows). It can therefore
fully replace all the other paffinity components.
Indeed, the new hwloc's default priority is higher than all of the other
current paffinity components, so over the next week or two, it'll be a good
soak test to see if it is working properly. Once we get any kinks worked out,
I propose removing all the other paffinity components and leaving only hwloc.
That being said, we might as well leave the paffinity framework around, even if
it only has one component left, simply on the argument that someday Open MPI
may support a platform that hwloc does not.
