Dear OpenMPI community,
This email is about whether a commercial version of OpenMPI for Windows
could be successful. I hesitated before sending this, but upon asking
some others (notably Jeff) on this list, it seemed appropriate.
We at Tech-X have been asking whether a commercial/freemium support
model for a Windows
version of OpenMPI would work. We are currently working on this for some
other products, notably PETSc, which is discussed at
http://www.txcorp.com/home/cosml.
We see some downsides - in particular, with Microsoft's HPC Pack,
Windows users
have free access to an MPI solution. This has to be balanced by some
particular advantages of OpenMPI such that there would be a group of
users who would pay for it for anyone to make this work.
We would be very interested in hearing from folks on this list who either
(1) help define the competitive advantage of having OpenMPI on Windows or
(2) would be interested in a commercial solution, were it available.
Naturally, any solution should benefit the OpenMPI community as well to
be a success.
I would be glad to hear from folks on list or off.
Thx....John Cary

All,
I completely missed the message about Shiqing departing as the OpenMPI
Windows maintainer. I'll try and keep Windows builds going for 1.6 at
least, I have 2011 and 2013 Intel licenses and VS2008 and 2012, but
not 2010. I see that the 1.6.3 code base already doesn't build on
Windows in VS2012 :-(.
While I can try and keep builds going, I don't have access to a
Windows cluster right now, and I'm flat out on two other projects. I
can test on my workstation, but that will only go so far. Longer-term,
there needs to be a decision made on whether Windows gets to be a
first-class citizen in OpenMPI or not. Jeff's already told me that
1.7 is lagging behind on Windows. It would be a shame to have all the
work Shiqing put in gradually decay because it can't be supported
enough. If there's any Microsoft/HPC/Azure folks observing this list,
or any other vendors who run on Windows with OpenMPI, maybe we can see
what can be done if you're interested.
Damien
