Installation on Expanse

Author: timo.heister@gmail.com

Installation on SDSC-Expanse.

For details see the Expanse User Guide

Some notes:

• to connect: ssh your-tacc-user-id@login.xsede.org followed by gsissh expanse.sdsc.xsede.org
• Do not work/compile on the login node, but submit an interactive job:

  srun --partition=compute  --pty --account=ucd150 --nodes=1 --ntasks-per-node=1 --cpus-per-task=128 \
  --mem=248G -t 02:00:00 --wait=0 --export=ALL /bin/bash
  

  Note: You need to set tasks-per-node and cpus-per-task like this for compilation, otherwise you can only compile on a single core.

Filesystems:

• /home/<userid>/ - NFS, not for parallel runs, 100GB
• /scratch/<userid>/job_<jobid>/ - fast, local to the node, will be wiped
• /expanse/lustre/projects/<projectnumber>/<userid>/ - parallel filesystem, good for parallel IO / large files.

Installation steps:

1. Pick installation directory:

export DEST=/expanse/lustre/projects/<projectnumber>/<userid>/libs-v3

2. Create and use enable.sh script

mkdir $DEST && cat > $DEST/enable.sh <<- EOM
  module reset
  module load slurm/expanse cpu gcc openmpi openblas cmake
  export CC=mpicc
  export CXX=mpicxx
  export FC=mpif77
EOM

. $DEST/enable.sh

3. Install deal.II

git clone https://github.com/dealii/candi/
cd candi

cat >> candi.cfg <<- EOM
NATIVE_OPTIMIZATIONS=true
DEAL_CONFOPTS=" -D DEAL_II_COMPONENT_EXAMPLES=OFF "
TRILINOS_CONFOPTS=" -D TPL_BLAS_LIBRARIES=$OPENBLASHOME/lib/libopenblas.so -D TPL_LAPACK_LIBRARIES=$OPENBLASHOME/lib/libopenblas.so "
EOM

./candi.sh -j 64 -p $DEST --platform=deal.II-toolchain/platforms/supported/centos7.platform --packages="once:hdf5 once:p4est once:trilinos dealii"

echo ". $DEST/configuration/enable.sh" >> $DEST/enable.sh

4. ASPECT

cd $HOME
. $DEST/enable.sh
git clone https://github.com/geodynamics/aspect.git
