Subject: [OMPI users] tester for cygwin openmpi-1.6.3 package
From: marco atzeri (marco.atzeri_at_[hidden])

Hi,
I built and packaged openmpi-1.6.3 for cygwin.
Before deploying it as an official package, I would
like feedback from testers.

Source and binary here:
http://matzeri.altervista.org/cygwin-1.7/openmpi/

To install using cygwin setup program
setup.exe -X -O -s http://matzeri.altervista.org

Current configuration is:

          LDFLAGS="-Wl,--export-all-symbols -no-undefined" \
                  --disable-mca-dso \
                 --without-udapl \
                 --enable-cxx-exceptions \
                 --with-threads=posix \
                 --without-cs-fs \
                 --enable-heterogeneous \
                 --with-mpi-param_check=always \
                 --enable-contrib-no-build=vt,libompitrace \
                 --enable-mca-nobuild= memory_mallopt, paffinity,
installdirs-windows, timer-windows, shmem-sysv

Only additional patch
https://svn.open-mpi.org/trac/ompi/changeset/27539

C, C++ and Fortran pass basic tests

$ time mpirun -n 4 ./hello_f90.exe
  Hello, world, I am 0 of 4
  Hello, world, I am 2 of 4
  Hello, world, I am 1 of 4
  Hello, world, I am 3 of 4

real 1m9.607s
user 0m1.542s
sys 0m2.135s

But I guess there is a long delay/timeout on startup.

Regards
Marco
