The code and objectives. I have a fortran mpi code called elast3dmpi.f to be compiled in both windows and linux systems. The expected behavior. The compilation in linux is performed as. Mpif90 -o elast3dmpi elast3dmpi.f Then the program can be executed in parallel with mpirun command. Mpirun -n 2 elast3dmpi.

Option 1: Installing Open MPI from precompiled binaries
-
Download the latest 64-bit compiled version of the Open MPI libraries for OS X ( version 1.8.3 ).
-
Copy the
openmpi...osx...tar.gz
file to the/shared
directory (you will need to create this directory if it doesn't currently exist). -
cd to
/shared
and run
which extracts the Open MPI libraries to
/shared/openmpi_64
.
-
Test the MPI version of FDS by typingYou should see the version number of FDS with no errors.
-
Run FDS MPI cases using the command:where
X
is the number of processors to use,fds
is the executable, andfds_case.fds
is the FDS case that you want to run. Note that you might need to add the location ofmpirun
(/shared/openmpi_64/bin
) to yourPATH
to use thempirun
command (if the FDS installer did not find the MPI distribution).
Option 2: Compiling Open MPI and FDS yourself
-
Install
Xcode
(free from the Mac App Store), which includes the 'Developer Tools'. -
Install the 'Command Line Tools' in
Xcode
(Preferences > Downloads). -
Install the OS X Intel C, C++, and Fortran compilers.
-
Download and extract Open MPI.
-
cd
to the directory that you extracted Open MPI to. -
Install Open MPI using the Intel compiler suite; configure and install using:
-
Build FDS MPI OS X version from the repository:
-
Run FDS cases using the command:where
X
is the number of processors to use,fds_mpi_executable
is the FDS MPI executable that was built in the above steps, andfds_case.fds
is the FDS case that you want to run. Note that you might need to add the location ofmpirun
(/shared/openmpi_64/bin
) to your PATH to use thempirun
command.
