These directions should be good on any of the Canadian super computer systems using the common StdEnv/2020 Compute [https://docs.computecanada.ca/wiki/Standard_software_environments#StdEnv.2F2020 Canada module software stack]

 == Download ISSM ==
You can download the development branch `trunk-jpl`:
{{{
#!sh
svn --username XXX --password XXX  checkout http://issm.ess.uci.edu/svn/issm/issm/trunk-jpl
}}}

== ssh configuration ==

You should first  create and upload an SSH key so you don't have to keep typing in your password. See directions: [https://docs.computecanada.ca/wiki/SSH_Keys]

== Environment ==
On Sherlock, add the following lines to `~/.bashrc`:
{{{
#!sh
module load gcc openmpi matlab metis parmetis imkl petsc
export ISSM_DIR=PATHTOTRUNK
source $ISSM_DIR/etc/environment.sh
}}}

Change PATHTOTRUNK to where `trunk-jpl` is located. Log out and log back in to apply this change.

 == Installing ISSM on the cluster  ==
You need to install the following packages in this exact sequence:
 - m1qn3 (install.sh)

Use the following configuration script (adapt to your needs):

{{{
#!sh
./configure \
	--prefix=$ISSM_DIR \
	--with-numthreads=2 \
        --with-mkl-libflags="-lmkl_gf_lp64 -lmkl_sequential  -lmkl_core -lmkl_blacs_openmpi_lp64 -lmkl_scalapack_lp64"\
	--with-petsc-dir="$EBROOTPETSC" \
        --with-mumps-dir="$EBROOTPETSC" \
	--with-m1qn3-dir="$ISSM_DIR/externalpackages/m1qn3/install" \
	--with-mpi-include="/some/path/just/to/enable" \
        --with-mpi-libflags="-lmpi_cxx -lmpi_mpifh -lmpi" \
        --with-fortran-lib="-L$EBROOTGCC/lib64 -lgfortran"
}}}

== computecanada_settings.m ==

You have to add a file in `$ISSM_DIR/src/m` entitled `computecanada _settings.m` with your personal settings:

{{{
#!m
cluster.login='XXX';
cluster.port=0;
cluster.codepath=XXX';
cluster.executionpath='XXX';
}}}

Use your username for the `login` and enter your `codepath` and `executionpath`. These settings will be picked up automatically by MATLAB when you do `md.cluster=computecanada()`
