Web page of the instalation of the ocean model CROCO in CIMA's HPC 'hydra'

Installation

CIMA's HPC has a common folder where all the people has access. This is going to be the place where CROCO model will be installed.

The installation is going to be in the following INSTALLDIR=/share/CROCO folder.

Downloading the code (there is a GItlab repository, but by now, we are going to install closed releases)

$ wget https://gitlab.inria.fr/croco-ocean/croco/-/archive/v2.1.0/croco-v2.1.0.tar.gz

Creating the folder of the compilation (using intel compiler and shared memory dmpar) and where to deploy the code

$ mkdir $INSTALLDIR/v210
$ cd $INSTALLDIR/v210
$ mkdir -p intel/dmpar
$ git clone --branch v2.1.0 https://gitlab.inria.fr/croco-ocean/croco.git croco-v2.1.0

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

Go to compile, first we set-up the environment for intel compilation

$ source /opt/load-libs.sh 1
The following libraries, compiled with Intel 2021.4.0 compilers, were loaded:
* MPICH 3.4.2
* NetCDF 4
* HDF5 1.10.5
* JASPER 2.0.33

To change it please logout and login again.

To load this libraries from within a script add this line to script:
source /opt/load-libs.sh 1
$ cd croco

We create an ASCII file with the specificities of the compilation with intel in hydra, name CROCO_hydra_intel.env (following the instructios from here tutorial 00)

#set environment variables for croco in HYDRA to be compiled with intel
source /opt/load-libs.sh 1
export CC=icc
export FC=ifort 
export F90=ifort 
export F77=ifort 
export NETCDF=/opt/netcdf/netcdf-4/intel/2021.4.0 
export PATH=$NETCDF/bin::${PATH} 
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}::${NETCDF}/lib

Loading the compilation environment

$ source CROCO_hydra_intel.env

BASIN

The simplest installation would be the 'basin' configuration. We follow these instructions basin. Assuming that the source code resides in CROCOsrc=/share/CROCO/v210/intel/dmpar/croco

$ CROCOsrc=/share/CROCO/v210/intel/dmpar/croco
$ cd ${CROCOsrc}
$ mkdir -p CONFIGS/BASIN
cp OCEAN/cppdefs.h CONFIGS/BASIN
cp OCEAN/param.h CONFIGS/BASIN
cp OCEAN/jobcomp CONFIGS/BASIN
cd CONFIGS/BASIN
