Building Firedrake on Archer2

Please follow the following to build and test Firedrake on Archer2.

1. Pick your work directory (e.g., /work/your_account/shared), set WORK environment variable, and cd to $WORK:

   export WORK=/your/work/dir
   mkdir -p $WORK
   cd $WORK

2. Pick Firedrake install directory (e.g., $WORK/firedrake) and set $FIREDRAKE_DIR environment variable:

   export FIREDRAKE_DIR=/your/firedrake/install/dir

3. Clone this repository in $FIREDRAKE_DIR:

   git clone https://github.com/firedrakeproject/firedrake-archer2.git $FIREDRAKE_DIR

4. Build Firedrake by running:

   bash $FIREDRAKE_DIR/firedrake_install_archer2.sh

   This will take about 30 minutes.
5. To test installation, move $FIREDRAKE_DIR/job.slurm and $FIREDRAKE_DIR/example.py to the current directory. In job.slurm, change the account name to your own account name and the FIREDRAKE_DIR environment variable to $FIREDRAKE_DIR and then submit the job:

   mv $FIREDRAKE_DIR/job.slurm job.slurm
   mv $FIREDRAKE_DIR/example.py example.py
   # Change account name and FIREDRAKE_DIR environment variable in job.slurm.
   sbatch job.slurm
