CC=mpicc CXX=mpicxx make install

Optional Dependencies:

spe10 dataset

Available at this page

unzip por_perm_case2a.zip -d ${HOME}/spe10

Valgrind

Some of our tests require valgrind, you can probably get it from your package manager or here. Then:

tar xvf valgrind-3.12.0
cd valgrind-3.12.0
./configure --prefix=${HOME}/valgrind-install
make
make install

Build smoothG

Clone the smoothG repo and cd into smoothG directory.

To build smoothG, either copy, modify, and run a config file from config/ or pass the parameters directly to cmake:

mkdir -p build
cd build

cmake \
    -DMFEM_DIR=${HOME}/mfem-install \
    -DMETIS_DIR=${HOME}/metis-install \
    -DHYPRE_DIR=${HOME}/hypre-install \
    -DSuiteSparse_DIR=${HOME}/suitesparse-install \
    -DCMAKE_BUILD_TYPE=DEBUG \
    -DSPE10_DIR=${HOME}/spe10 \
    ..

make
make test
make doc

Notes:

Metis gives you the option of choosing between float and double as your real type by altering the REALTYPEWIDTH constant in metis.h. To pass our tests, you need to have REALTYPEWIDTH set to 32 (resulting in float for your real type).
