4 months ago When building for a CPU based system, you may need to specify the name of the launch command by adding a line such as the following
-D MPIEXEC=mpirun \
See below for an example https://github.com/OPM/LBPM/blob/master/sample_scripts/configure_cascades_cpu
For GPU applications it is more complicated, because the launch command may also need additional flags / arguments to specify how to launch the application within your environment. This often depends on the MPI implementation (e.g openmpi or mvapich2), how the MPI implementation was compiled, and on other factors (such as if a scheduler like slurm is being used as the launcher).
[root@bogon installer]# cat configureYDWCPU
load the module for cmake
export LBPM_SOURCE="/soft/ops/LBPM-slim-master/" export LBPM_DIR="/usr/local/lbpm"
mkdir $LBPM_DIR cd $LBPM_DIR
configure
rm -rf CMake* cmake \ -D CMAKE_BUILD_TYPE:STRING=Release \ -D CMAKE_CXX_COMPILER:PATH=mpicxx \ -D USE_MPI=1 \ $LBPM_SOURCE make -j32 && make install && ctest
