To compile and install hwcart you need CMake, a working MPI environment,
and an installation of the hwloc library and headers.
First, clone the repository:
git clone [email protected]:NordicHPC/hwcart.git
Create the build directory
mkdir hwcart/build
cd hwcart/build
Configure using CMake:
cmake ..
You can set the following CMake variables:
HWCART_USE_FORTRAN (default OFF) Choose whether to build Fortran interface
HWCART_USE_HWLOC (default ON) Choose whether to use hwloc (OpenMPI is required if hwloc is not used)
HWCART_USE_TESTS (default OFF) Choose whether to build tests and examples
Note that if the OpenMPI environment is used, it is possible to compile and use hwcart without hwloc.
In that case hwcart will use the OpenMPI hardware locality features instead.
To compile and install:
make install
