For your fortran issue, the Fortran 90 interface needs the Fortran 77

configure

interface was disabled).
Is that what you mean (see below)?
Ah yes -- that's another reason the f90 interface could be disabled:
if configure detects that the f77 and f90 compilers are not link-
compatible.
I thought the g95 compiler could
deal with F77 as well as F95... If so, could I just pass F77='g95'?
That would probably work (F77=g95). I don't know the g95 compiler at
all, so I don't know if it also accepts Fortran-77-style codes. But
if it does, then you're set. Otherwise, specify a different F77
compiler that is link compatible with g95 and you should be good.
I looked in some places in the OpenMPI code, but I couldn't find
"max" being redefined anywhere, but I may be looking in the wrong
places. Anyways, the only way of found of compiling OpenMPI was a
very
ugly hack: I have to go into those files and remove the "std::"
before
the "max". With that, it all compiled cleanly.
I'm not sure I follow -- I don't see anywhere in OMPI where we use
std::max.
What areas did you find that you needed to change?
These files are part of the standard C++ headers. In my case, they
sit in:
/usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/bits
Ah, I see.
In principle, the problems that comes from those files would mean that
the OpenMPI source has some macro redefining max, but that's what I
could not find :-(
Gotcha. I don't think we are defining a "max" macro anywhere in the
ompi_info source or related header files. :-(
No. We don't really maintain the "make check" stuff too well.
Oh well... What do you use for testing the implementation?
We have a whole pile of MPI tests in a private SVN repository. The
repository is only private because it contains a lot of other people's
[public] MPI test suites and benchmarks, and we never looked into
redistribution rights for their software. There's nothing really
secret about it -- we just haven't bothered to look into the IP
issues. :-)
We use the MPI Testing Tool (MTT) for nightly regression across the
community:
http://www.open-mpi.org/mtt/
We have weekday and weekend testing schedules. M-Th we do nightly
tests; F-Mon morning, we do a long weekend schedule. This weekend,
for example, we ran about 675k regression tests:
