clear that we have very many Windows users in HPC land, and the cygwin
port already exists anyway. However, I probably will do it for sometime
in the 1.9 series.

Well, I (and dgoodell and jsquyers and probably a few others of you) can say from observing disc...@mpich.org traffic that we get one message about Windows support every month -- probably more often. There's clearly a community of Windows users out there looking for a free MPI implementation.

Sorry to hear that MS-MPI is not yet MPI-3 compliant. There is also Intel-MPI and Platform-MPI but I think you have to license those?

Dear people,
As a continuation of the hint of   Damien   , who suggested using
MPICH on WIN7 :
MPICH has already stopped supporting WINDOWS in the past. MPICH
recommends using  MS-MPI for WINDOWS, which is a derivative from MPICH2.
You may download the binary (for free) from the landing page for
MS-MPI: http://msdn.microsoft.com/en-us/library/bb524831(v=vs.85).aspx
Most recent version is:        version: 4.2.4400.0   Date published:
1/14/2014
However note, that MS-MPI does conform to MPI-2, not yet to MPI-3.
The installation is easy and it works well with my CFD-code under WIN7
(64-bit).
Greetings
Michael Rachner

Guys,

Don't do it.  It doesn't work at all.  I couldn't pick up maintenance
of it either, and the majority of the Windows support is removed as
Ralph said.  Just use MPICH for Windows work and save yourself the pain.

Cheers,

Damien

    It likely won't build because last I check the Microsoft toolchain does

    not fit the minimum requirements (C99 or higher). You will have better

    luck with either gcc or intel's compiler.

        hello,

        I'm about to try to build 1.8.1 with win msvc2013 toolkit in 64bit mode.

        I know the win binaries were dropped after failure to find someone to

        pick them up (following shiqin departure), and i'm afraid I wouldn't

        volunteer due to lack of time, but is there any general advice before

        I start?



        rds,

        MM
