Compiling and installing sparta

cd /path/to/sparta

# Create a clean in-source build directory
rm -rf build
mkdir build install
cd build

# Configure the build system
cmake -DCMAKE_INSTALL_PREFIX=../install /path/to/sparta/cmake

# List project-specific options
cmake -L /path/to/sparta/cmake

# List project-specific options and help strings
cmake -LH /path/to/sparta/cmake

# List all options and help strings
cmake -LAH

# Show all generated targets
make help

# Build the project
make

# Install the binaries and libraries
make install

Sparta preset files

The sparta build system provides commonly used configuration settings as cmake files under /path/to/sparta/cmake/presets. This allows developers to quickly set configuration knobs before building sparta.

Examples

Using a preset file

cmake -C /path/to/<NAME>.cmake /path/to/sparta/cmake

Sparta Keyword Listing

Package options

  • PKG_FFT
    • Whether to enable the Sparta FFT package.
  • PKG_KOKKOS
    • Whether to enable the Sparta KOKKOS package.
  • PKG_MPI_STUBS
    • Whether to enable the Sparta MPI_STUBS package.

Third Party Library (TPL) options

  • BUILD_KOKKOS
    • Whether to enable the Sparta KOKKOS TPL.
  • BUILD_MPI
    • Whether to enable the Sparta MPI TPL.
  • BUILD_JPEG
    • Whether to enable the Sparta JPEG TPL.
  • BUILD_PNG
    • Whether to enable the Sparta PNG TPL.
  • BUILD_MPI
    • Whether to enable the Sparta MPI TPL.
  • FFT
    • Which Sparta FFT TPL to enable: FFTW2, FFTW3, or MKL.

Note: To point to a TPL installation, export _ROOT=/path/to/tpl/install before running cmake.

Other options

  • SPARTA_MACHINE
    • String to form the spa_$SPARTA_MACHINE binary file name.
  • SPARTA_CXX_COMPILE_FLAGS
    • Selected compiler flags used when building object files for spa_$SPARTA_MACHINE.
  • SPARTA_DEFAULT_CXX_COMPILE_FLAGS
    • Default compiler flags used when building object files for spa_$SPARTA_MACHINE.
  • SPARTA_LIST_PKGS
    • Print the Sparta packages and exit.
  • SPARTA_LIST_TPLS
    • Print the Sparta TPLs and exit.
  • SPARTA_ENABLE_TESTING
    • Add tests in examples to be run via ctest.
  • SPARTA_DSMC_TESTING_PATH
    • Add tests in SPARTA_DSMC_TESTING_PATH/examples to be run via ctest.
    • Run all tests via SPARTA_DSMC_TESTING_PATH/regression.py.
  • SPARTA_SPA_ARGS
    • Additional arguments for the sparta binary. Only applied if SPARTA_ENABLE_TESTING or SPARTA_DSMC_TESTING_PATH are enabled.
  • SPARTA_DSMC_TESTING_DRIVER_ARGS
    • Additional arguments for SPARTA_DSMC_TESTING_PATH/regression.py.
  • SPARTA_CTEST_CONFIGS
    • Additional ctest configurations, separated by ;, that allow SPARTA_SPA_ARGS_<CONFIG_NAME> or SPARTA_DSMC_TESTING_DRIVER_ARGS_<CONFIG_NAME> to be specified.
  • SPARTA_MULTIBUILD_CONFIGS
    • Additional build configurations, separated by ;, build sparta with the cache file from SPARTA_MULTIBUILD_PRESET_DIR/<CONFIG_NAME>.cmake.
  • SPARTA_MULTIBUILD_PRESET_DIR
    • The path to custom preset files when using SPARTA_MULTIBUILD_CONFIGS. Only applied if SPARTA_MULTIBUILD_CONFIGS is enabled.

Examples

Selecting packages via the command line

cmake -DPKG_<NAME>=[ON|OFF] /path/to/sparta/cmake

Selecting TPLs via the command line

cmake -DBUILD_<NAME>_TPL=[ON|OFF] /path/to/sparta/cmake

Specifying build flags via the command line

cmake -DSPARTA_DEFAULT_CXX_COMPILE_FLAGS=<FLAGS> /path/to/sparta/cmake

Specifying multiple ctest configurations via the command line

cmake -DSPARTA_CTEST_CONFIGS="PARALLEL;SERIAL" \
      -DSPARTA_SPA_ARGS_SERIAL=spa_args \
      -DSPARTA_DSMC_TESTING_DRIVER_ARGS_PARALLEL=driver_args \
      /path/to/sparta/cmake

make -j

ctest -C SERIAL
ctest -C PARALLEL

Specifying multiple build configurations via the command line

# Assumes that /path/to/sparta/cmake/presets/{test_mac_mpi,test_mac}.cmake exist
cmake -DSPARTA_MULTIBUILD_CONFIGS="test_mac;test_mac_mpi" \
      -DSPARTA_MULTIBUILD_PRESET_DIR=/path/to/sparta/cmake/presets/ \
      /path/to/sparta/cmake

make -j

ctest -VV

Build system design

Targets and dependency resolution

This build system consists of four targets:

  1. spa_$CONFIG_STRING: The final sparta executable
  2. pkg_fft: The optional FFT package
  3. pkg_mpi_stubs: The optional MPI STUBS package
  4. pkg_kokkos: The optional kokkos wrapper package

Every target is responsible for resolving its own dependencies. Every target A that relies on another target B will pull in the dependencies that target B resolved.

Targets 2-4 are all optional packages that are built as static libraries.

Target 1 links against targets 2-4 (if enabled).

The structure of the sparta/cmake directory

This directory contains two directories: common and presets.

presets

Contains preset options that can be selected via: cmake -C /path/to/presets/<NAME>.cmake

common

Contains three directories: set, process, and print. Each of these directories contains cmake files that are included by the top-level CMakeLists.txt file in sparta. These common cmake files set build options, process those build options, and finally print the settings that were selected.

Build system triaging

Quick start

cmake --log-level=VERBOSE [-C /path/to/sparta/cmake/presets/<NAME>.cmake] /path/to/sparta/cmake
make VERBOSE=1
