Greetings,
CygWin is interesting intermediating environment between Windows and Linux-like
architectures, and the OpenMPI project is good platform for enabling parallel
calculations.
Here is my OpenMPI building experience with some problems encountered (with
up-to-date CygWin & OpenMPI):
cygwin already provides openmpi 1.8.5 package.
1) the "default" OpenMPI configuration (no special flags) gives these linking
errors:
the packages are built with
--disable-mca-dso \
--disable-sysv-shmem \
--enable-cxx-exceptions \
--with-threads=posix \
--without-cs-fs \
--with-mpi-param_check=always \
--enable-contrib-no-build=vt,libompitrace \
--enable-mca-no-build=paffinity,installdirs-windows,timer-windows,shmem-sysv
2) The OpenMPI configuration with the flags specified by
https://www.open-mpi.org/community/lists/users/2014/04/24166.php
produces working mpif90,mpicc,mpicxx... executables.
However, the "make check" testing gives the second test wrong (see below).
the only current failure is on x86_64
assertion "opal_atomic_cmpset
all the other tests pass.
Any help how to fix this test issue ?
use cygwin packages
