Building on Lassen

Quick and dirty build example on Lassen

• [One time only], make sure git lfs is enabled by running the following prior to cloning the TPS repo:

git-lfs install

• setup gcc/MPI environment:

ml swap xl gcc/8.3.1

• setup modules environment to access installs in our shared space:

# shared s/w location where missing 3rd party libs are installed
export SW_HOME=/usr/workspace/utaustin/software/lassen
export MODULEPATH=$SW_HOME/modules/gcc:$MODULEPATH

• load 3rd party libs necessary for TPS build (this assumes GPU variant)

module load grvy mfem-cuda hypre metis cuda/11.2.0

• update path to resolve bats for regression tests:

export PATH=$SW_HOME/bats-1.3.0/bin:$PATH

Now, you should be able to build from cloned repo as follows:

./bootstrap
./configure CUDA_ARCH=sm_70 --enable-gpu-cuda --with-cuda=$CUDA_HOME --disable-valgrind
make -j 4

If all went well, you have a libtps.a library and tps executable in the src/ subdirectory. You can now run a quick check on a compute node. You can access a compute node interactively on Lassen as follows (30 minute example):

$ bsub -nnodes 1 -Ip  -W 30 /bin/bash

[now on compute node, run test suite...]
make check
