I don't see the MCA parameter "mpi_paffinity_alone" anymore:
[4:54] svbu-mpi:~/svn/ompi2 % ompi_info --param all all | grep
MCA opal: parameter "opal_paffinity_alone" (current
[4:54] svbu-mpi:~/svn/ompi2 %
My point is that I don't think we should delete this parameter; there
is historical precedence for it (and it has been documented on the web
page for a long, long time). Perhaps it can now simply be a synonym
for opal_paffinity_alone (registered in the MPI layer, not opal).
