Understood; this was a more complete/precise meaning for my

it's only really useful for the OpenFabrics and [ancient] Myricom

That should be good enough, at least for that part. Or testing first
for the presence of OpenFabrics or Myricom? Maybe it could just test
for the existence of GNU extensions? I don't know. I understand it
must be really hard to keep track of what is standard and what is not
these days. I'm just thankful that you guys are looking into it.
Thanks!
My plate is pretty full trying to get v1.3.0 out the door and prepare
for SC -- I don't know if this will be fixed before then. But I've
opened a ticket about it:
https://svn.open-mpi.org/trac/ompi/ticket/1618
Well... I don't. It's just that, due to specifics of my work, I need
to work on a Windows computer, but I also like to use many unix
features / commands. So, I just use Cygwin out of convenience, which
in a way gives me the best of both worlds without the need to dual
boot.
Fair enough.
However, the other reason I use Cygwin is because I work in the
development of a program and it is very convenient to do that in
Cygwin, especially when I'm traveling and only have access to my
laptop. Many users have this program running in Cygwin, so it's also
good to have a place to test it. I don't really use Cygwin for the
long "production" runs that would actually require a MPI, for that I
have access to local clusters or Teragrid. My problem is testing the
parallel version in Cygwin (or if any changes made break the parallel
implementation) because I still did not manage to install a MPI in
Cygwin.
In fact, I have never tried a VM :-$ I guess I should give it a try
sometime. Do you have any recommendations? My only requirements are
that (i) it works, (ii) it's free.
I don't know if there are free VM's or not, but you could try a 30 day
free trial of vmware (or equivalent) and see if you like it. IIRC,
it's not terribly expensive if you end up liking it. :-)
FWIW: I use Parallels (an OS X VM) on my Mac because Cisco lives and
dies by Outlook calendaring. :-)
