The code_ex2_metis code uses cmake to build all source files. This is intended for an "out of source build", namely used like this:
- To build and run using available ParMETIS module in K:
#!bash
module purge
module load ParMetis_4.0.3_openmpi_1.8.6_gcc cmake_3.14.0
mkdir -p build
cd build
cmake ..
#or ccmake ..; See further instructions using ccmake below.
make -j install
In ccmake just configure (c) and generate and exit (g). configure (c) button may have to be done more than once before generate and exit (g) stage pops out. Ensure With ParMETIS is turned ON. Build type is irrelevant (default is Release). Default install directory is ../install and will be automatically generated.
To run:
#!bash
cd build
mpiexec -np <nprocs> ../install/bin/parmetis_test # or mpiexec -np <nprocs> ./ex_parmetis/parmetis_test
- To build and run using locally installed ParMETIS:
#!bash
module purge
module load openmpi_2.1.1_gcc_6.2 gcc_6.2.0 cmake_3.14.0
mkdir -p build
cd build
cmake -DCMAKE_CXX_COMPILER=$( which mpicxx ) \
-DCMAKE_C_COMPILER=$( which mpicc ) \
-DCMAKE_PREFIX_PATH=$HOME/local \
../
make -j install
# This step is necessary if not already done in .bashrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/local/lib
mpiexec -np <nprocs> ../install/bin/partmesh # or mpiexec -np <nprocs> ./ex_partmesh/partmesh
../install/bin/partmesh # or ./ex_partmesh/partmesh # for single proc test
