Hello, all,
I'm attempting to install Open MPI in a cygwin environment on Windows 7
(64-bit, but I think Open MPI is treating things like a 32-bit environment).
Hi Don,
cygwin already has a 1.7.1 package
$ cygcheck -c -d |grep mpi
libopenmpi 1.7.1-2
libopenmpi-devel 1.7.1-2
libopenmpicxx1 1.7.1-2
libopenmpifh2 1.7.1-2
libopenmpiuse1 1.7.1-2
openmpi 1.7.1-2
any reason to not use it ?
Any reason to need 1.6.5 ?
Cygwin is 32 bit enviroment, so of coure the package is 32bit;
However cygwin64, still beta, already has the same package version
$ cygcheck -c -d |grep mpi
libopenmpi 1.7.1-2
libopenmpi-devel 1.7.1-2
libopenmpicxx1 1.7.1-2
libopenmpifh2 1.7.1-2
libopenmpiuse1 1.7.1-2
openmpi 1.7.1-2
The command I used to configure Open MPI was
-----------------------
./configure --with-mpi-f90-size=medium -prefix=/home/Don/openmpi
F77=gfortran FC=gfortran
-----------------------
too little ;-)
current 1.7.1-2 package is built with:
configure \
LDFLAGS="-Wl,--export-all-symbols -no-undefined" \
--disable-mca-dso \
--disable-sysv-shmem \
--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-no-build=paffinity,installdirs-windows,timer-windows,shmem-sysv
and I had a similar one on previous 1.6.4-2 package
