The mpi3-greq list hasn't had any activity in five years, so it's not
clear any interested parties are there. I care quite a bit about
improving the ability of generalized requests to make progress, mostly
because I want to be able to implement domain-specific nonblocking
collectives with similar progress semantics to those provided directly
by MPI.
https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Proposal has
stalled. If you want to go to Spain in September and try to push it
forward, I think people might be willing to help you.
At this point, you should subscribe to
http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi3-greq and have
further discussion of this issue there. I copied that list to make
the transition seemless.
Best,
Jeff
