# INSTRUCTIONS FOR COMPILING AND RUNNING ON TITAN
# Note: there are 3 directories of interest:
#    source directory - assumed to be located at ${HOME}/LBPM-WIA for these instructions, but may be anywhere
#    build directory  - current directory used for building, may not be the source directory, generally should be on lustre
#    install directory - installation directory, optional, may be the same as the build directory, 
#                        generally should be on lustre, specified with "-D LBPM_INSTALL_DIR:PATH="path_tot_install"

module load cudatoolkit


# load the module for cmake

# Build and install (may be done in parallel)
make install -j 8


# Run the tests (optional, requires that were are in an interactive session)
# Note: to run the tests and submit the results to CDash, see "run_ctest_titan"
#    in sample_scripts, which uses the "config_titan" and "ctest_titan.ctest"
# Run the fast tests:
ctest -E WEEKLY
# Run all tests
ctest
