0405 Compilation ParMETIS Linux

Compiling INMOST with ParMETIS on Linux

INMOST may be configured with optional ParMETIS support. In this case INMOST will support calling graph partitioner from ParMETIS package, i.e. you will be able to use Partitioner::Parmetis in Partitioner::SetMethod.

INMOST requires ParMETIS version 4.0 or higher.

To install ParMETIS yourself, download version 4.03 from http://glaros.dtc.umn.edu/gkhome/metis/parmetis/download.

You can do it using the following command:

wget http://glaros.dtc.umn.edu/gkhome/fetch/sw/parmetis/parmetis-4.0.3.tar.gz

Unpack the package with the command

tar -xzf parmetis-4.0.3.tar.gz

Remember the path where you are working:

export home=`pwd`

Open parmetis-4.0.3/CMakeLists.txt file for edit and replace following two lines:

set(GKLIB_PATH METIS/GKlib CACHE PATH "path to GKlib")
set(METIS_PATH METIS/metis CACHE PATH "path to METIS")

With three following lines:

find_package(MPI)
set(GKLIB_PATH ${CMAKE_SOURCE_DIR}/metis/GKlib CACHE PATH "path to GKlib")
set(METIS_PATH ${CMAKE_SOURCE_DIR}/metis CACHE PATH "path to METIS")

Now cmake would be able to correctly recognize all the paths and to automatically find the MPI library.

Create the parmetis-build directory and run the following commands from it:

cmake ../parmetis-4.0.3/. && make

Once you have compiled ParMETIS, provide the following options to CMake configure script of INMOST:

cmake -DUSE_SOLVER_METIS=ON \
      -DUSE_PARTITIONER_PARMETIS=ON \
      -DMETIS_LIBRARY="$home/parmetis-build/libmetis/libmetis.a" \
      -DMETIS_INCLUDE_DIR="$home/parmetis-4.0.3/metis/include" \
      -DPARMETIS_LIBRARY="$home/parmetis-library/libparmetis/libparmetis.a" \
      -DPARMETIS_INCLUDE_DIR="$home/parmetis-4.0.3/include"

Install ParMETIS with PETSc

PETSc installation guideconfigure script just add --download-metis --download-parmetis like this:

cd "$INMOST_ROOT"
wget http://ftp.mcs.anl.gov/pub/petsc/release-snapshots/petsc-lite-3.5.2.tar.gz
tar zxf petsc-lite-3.5.2.tar.gz
cd petsc-3.5.2
export PETSC_DIR="`pwd`"
export PETSC_ARCH=linux-gnu-debug
./configure --download-metis --download-parmetis

cd "$INMOST_ROOT"
mkdir -p INMOST-build
cd INMOST-build
cmake -DUSE_PARTITIONER_PARMETIS=ON -DPARMETIS_DIR="$PETSC_DIR/$PETSC_ARCH" ../INMOST-0.1
make all
