Building on Mac High Sierra

This page is currently under development. Please excuse inconsistencies.

This details the building of GridPACK on a Macbook Pro running Mac OS X High Sierra (10.13.6). The build was aided by the use of MacPorts to install some prerequisite software. Super user permissions are required to install and manage MacPorts.

These instructions use a specific combination of compilers, MPI implementation, and MacPorts packages. Other combinations can be used, the one here happened to work for the author. If you choose some other combination, you're on your own.

The author uses the C-shell. These instructions will need to be slightly modified to adapt to another shell, like bash.

MacPorts

The easiest way to get GridPACK going on Mac OS X is to use MacPorts to install (some of) the needed prerequisite software. MacPorts is free, open source system whereby various software packages can be installed and maintained on a Mac OS X system. Homebrew provides a similar capability, but the author has no experience with it.

The MacPorts project provides very good installation instructions. They will not be repeated here. It is assumed here that MacPorts was installed in /opt/local, which is the default.

After MacPorts installation, /opt/local/bin needs to be in shell search path. The easiest way to do this is to add /opt/local/bin to the top of /etc/paths (superuser privileges required). Afterward, a reboot or starting a new shell should make the port command available on the command line.

Packages from MacPorts

Install the CLang 6.0 compiler set, mpich MPI implementation, and Boost with Boost.MPI using the following:

sudo port install boost +clang60+mpich

Make the installed compilers and MPI wrappers the default.

sudo port select --set clang mp-clang-6.0
sudo port select --set mpi mpich-clang60-fortran

That way the compiler commands, clang and clang++, and MPI compiler wrappers, like mpicc, will be available at the command line.

Install CMake and the GNU linear programming kit:

sudo port install cmake
sudo port install glpk

Build Packages from Source

PETSc and Global Arrays need to be built from source. You need to choose a path in which packages will be installed. Here the author decided to use a single installation directory, $HOME/gridpack. Directories or architecture variables that should be set to reflect local user environments are colored red.

PETSc, version 3.8.4

Download the PETSc source. It is recommended to unpack this in the installation directory ($HOME/gridpack). Configure and build PETSc using

setenv PETSC_DIR $HOME/gridpack/petsc-3.8.4
unsetenv PETSC_ARCH
./configure \
   PETSC_ARCH=arch-macosx-clang-real-opt \
   COPTFLAGS="-g -O2" \
   CXXOPTFLAGS="-g -O2" \
   FOPTFLAGS="-g -O2" \
   --with-prefix="$HOME/gridpack" \
   --with-mpi=1 \
   --with-gnu-compilers=0 \
   --with-cc=/opt/local/bin/mpicc \
   --with-fc=/opt/local/bin/mpif90 \
   --with-cxx=/opt/local/bin/mpicxx \
   --with-clanguage=c++ \
   --with-fortran-bindings=0 \
   --with-scalar-type=real \
   --with-precision=double \
   --download-suitesparse=1 \
   --download-superlu_dist=1 \
   --download-parmetis=1 \
   --download-metis=1 \
   --download-f2cblaslapack=1 \
   --download-mumps=0 \
   --download-scalapack=1 \
   --with-shared-libraries=0 \
   --with-x=0 \
   --with-valgrind=0 \
   --with-mpiexec=mpiexec \
   --with-debugging=0 
make PETSC_DIR=$HOME/gridpack/petsc-3.8.4 PETSC_ARCH=arch-macosx-clang-real-opt all
make PETSC_DIR=$HOME/gridpack/petsc-3.8.4 PETSC_ARCH=arch-macosx-clang-real-opt test

Global Arrays, version 5.7

Download the source from here and unpack in a convenient location. In the unpacked directory, configure, build, and install [[1][Global Arrays]] like this

mkdir build
cd build
../configure \
   --enable-cxx \
   --disable-f77 \
   --enable-i4 \
   --with-mpi \
   --with-mpi-ts \
   --enable-autodetect=yes \
   --prefix="$HOME/gridpack" \
   --without-blas \
   --without-lapack \
   --without-scalapack \
   --enable-shared=no \
   --enable-static=yes \
   MPICC=mpicc MPICXX=mpicxx MPIF77=mpif90 \
   MPIEXEC=mpiexec MPIRUN=mpirun \
   LDFLAGS="-L/opt/local/lib"
make
make install

GridPACK

CMake will work very hard to choose the wrong compiler. Make sure it uses the correct compiler by setting environment variables as follows:

setenv CC /opt/local/bin/clang
setenv CXX /opt/local/bin/clang++

Configure, build, and test GridPACK with

rm -rf CMake*
cmake \
   -D GA_DIR:STRING="$HOME/gridpack" \
   -D BOOST_ROOT:STRING="/opt/local" \
   -D PETSC_DIR:PATH="$HOME/gridpack/petsc-3.8.4" \
   -D PETSC_ARCH:STRING="arch-macosx-clang-real-opt" \
   -D MPI_CXX_COMPILER:STRING='/opt/local/bin/mpicxx' \
   -D MPI_C_COMPILER:STRING='/opt/local/bin/mpicc' \
   -D MPIEXEC:STRING='/opt/local/bin/mpiexec' \
   -D MPIEXEC_MAX_NUMPROCS:STRING="2" \
   -D GRIDPACK_TEST_TIMEOUT:STRING=30 \
   -D USE_GLPK:BOOL=ON \
   -D GLPK_ROOT_DIR:PATH="/opt/local" \
   -D CMAKE_INSTALL_PREFIX:PATH="$HOME/gridpack" \
   ..
make
make test

Observations

It appears that at the time of writing the OpenMPI ports are not Boost or PETSc compatible. Stick with mpich.

Boost.MPI compiled with the stock XCode C++ compiler seems to have trouble with serialization needed in the GridPACK code. This may or may not be a real issue. Little effort was expended to track it down, since Boost.MPI appears to work fine on Mac OS X if compiled with another CLang-based compiler.

MacPorts does have a PETSc package, but it will not work for GridPACK because it does not have the required C++ support built in.

PETSc must be later than 3.8. Versions 3.7.x do not configure properly with up to date XCode. This is a known issue that was fixed in 3.8.x.
