They can disagree as much as they want. I've spent over 30 years doing
contracts for and associated with MS and am very familiar with their
policy of what they claim vs. what they do. Check out:
http://mpi-forum.org/slides/2014/11/mpi3-impl-status-Nov14.pdf
for where msmpi was in 2014 when they were claiming the same things. The
latest version of msmpi (v8.1.12438) still only provides minimal support
for MPI specification v2.0.
Understand, I'm no MS basher; Windows is still the most likely
development environment in the industry and must be respected. This is
why I always argue that it is a mistake not to distribute native MS
versions of packages no matter what level of popular support there is.
Allowing MS to restrict the level of support on the Windows platform to
only the avenues they wish developers to use is a huge restriction for
the evolution of a specification and a terrible problem for those of us
who must work cross-platform.
However, my original point was about the Cygwin version of openmpi and
not any native Windows version. Looking forward to that. :)
