Now we are ready to set-up the case.

Going to the folder with the case (<CODE>$ROOTCASE</CODE> folder as it is understood)

First error related to python...

It happens everywhere, so, either I ask my IT team (as root) to fix it by creating a symlink to python, but based in python3 (see [https://stackoverflow.com/questions/3655306/ubuntu-usr-bin-env-python-no-such-file-or-directory here])

<PRE style="shell">

# ln -s /usr/bin/python3 /usr/bin/python

Or I go back to the <CODE>cism/scripts</CODE> folder and change it everywhere...

intel compilation

CIMA's hydra intel configuration is done via the following instruction: 

$ 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

Which creates the following environment:

Downloading CESM2

Following CESM2 Quick Start Guide and CESM2 github instructions and this tutorial

Cloning the code for version 2.2.2: 

$ mkdir -p CESM/v2.2.2/intel
$ git clone -b release-cesm2.2.2 git@github.com:ESCOMP/CESM.git my_cesm_sandbox

This will create a directory my_cesm_sandbox/ in your current working directory.

We got the following 

$ cd my_cesm_sandbox/
$ ls
ChangeLog           CODE_OF_CONDUCT.md  Externals.cfg       manage_externals
ChangeLog_template  describe_version    Externals_cime.cfg  README.rst
cime_config         doc                 LICENSE.txt

Verifying that installation was fine: 

$ ./manage_externals/checkout_externals
$ ls 
ChangeLog           CODE_OF_CONDUCT.md  Externals.cfg       README.rst

Defining the compilation / installation

Machine

We need to create the configuration for hydra. For that purpose we are going to use the exampled configuration for "centos7-linux" from file 
cime/config/cesm/machines/config_machines.xml
. This is its content:

Creation of the hydra's CESM main folders 

$ mkdir /share/cesm/expriments/
$ mkdir /share/cesm/inputdata

Compilers

Configuration of the compilers is done via the file cime/config/cesm/machines/config_cmopilers.xml.

Some modifications are introduced in order to make sure that compilation is done throughtout hydra's intel configration 

$ cp cime/config/cesm/machines/config_compilers.xml cime/config/cesm/machines/config_compilers_orig.xml
$ diff cime/config/cesm/machines/config_compilers.xml cime/config/cesm/machines/config_compilers_orig.xml

PIO

Configuration of the Parallel I/O Library (PIO) used for the input/output of the model is done with the file cime/config/cesm/machines/config_pio.xml.

By now it is left as it is provided.

Batch

Configuration of the batch system is done with the file cime/config/cesm/machines/config_batch.xml

A new configuration has been added for hydra pbs queue system 

$ cp cime/config/cesm/machines/config_batch.xml cime/config/cesm/machines/config_batch_orig.xml
$ diff cime/config/cesm/machines/config_batch.xml cime/config/cesm/machines/config_batch_orig.xml

Work-flow

configuration of the work-flow is done via the file cime/config/cesm/machines/config_batch.xml

By now is it left as it is.


Case creation

Prior to the compilation, we need to make sure that all the optional additional components have already been compiled (see next section). After that we are going to use cime/scripts/create_newcase to compile and use the model. The model is compiled for each new experiment, since user might activate different components each time and compiling only the required components makes the simulation more efficient. 

./create_newcase --case [CaseName] --res [Resolution] --compset [Compset] --mach hydra

Where:

  • [CaseName]: Convention for the name of the experiment is done following this CESM Naming conventions web-page
  • [Resolution]: Available resolutions to use from CESM grids (not working). (We can use either: python3 cime/scripts/query_config --grids --full)
  • [Compset]: Componets activated
  • hydra: HPC to use 
$ source /opt/load-libs.sh 1
$ cd cime/scripts/
$ ./create_newcase --case /share/cesm/expriments/b.day1.0 --res f19_g17 --compset B1850 --mach hydra >& run_create_newcase.log

Errors found

One must be aware, that it seems that error messages are not quite informative (by now)

Checking for the correct execution in file run_create_newcase.log and an error message is detected: 

xmllint not found,...

Which seems to be related to the absence of the package libxml2-utils

New error: 

Compset specific settings: name is RUN_STARTDATE and value is 0001-01-01

ita/CESM/v2.2.2/intel/my_cesm_sandbox/cime/scripts'

machine configuration for hydra was lacking, that it does not have modules, so it was included: 

(...)
    </mpirun>
    <module_system type="none"/>
(...)

Queue-system related error: 

Batch_system_type is pbs
job is case.run USER_REQUESTED_WALLTIME None USER_REQUESTED_QUEUE None WALLTIME_FORMAT %H:%M:%S
WARNING: No queue on this system met the requirements for this job. Falling back to defaults
ERROR: No queues found

No queue system was created for hydra. Now it has been added into cime/config/cesm/machines/config_batch.xml

Case setup

Now we are ready to set-up the case.

Going to the folder with the case ($ROOTCASE folder as it is understood) 

$ cd /share/cesm/expriments/b.day1.0
$ ./case.setup >& run_case-setup.log

errors

First error related to python... 

$ ./case.setup 
/usr/bin/env: ‘python’: No such file or directory

Modifying it to use python3 

$ cp case.setup case.setup_orig
$ diff case.setup case.setup_orig
1c1
< #!/usr/bin/env python3
---
> #!/usr/bin/env python

It happens everywhere, so, either I ask my IT team (as root) to fix it by creating a symlink to python, but based in python3 (see here) 

# ln -s /usr/bin/python3 /usr/bin/python

Or I go back to the cism/scripts folder and change it everywhere...

Optional additional components

ESM

It is necessary the High Performance Modeling Infrastructure (ESM) in May 2024, the latest version was the 8.6.0 and is the one being installed.

Getting the code in hydra in folder ESM 

$ wget https://github.com/esmf-org/esmf/archive/refs/tags/v8.6.0.tar.gz

Compilation is done following these documentation, which the right detailed procedure specific-compilation-instructions.

GNU compilation

Installation location 

$ mkdir -p v860/gnu
$ cd v860/gnu
$ tar xvfz ../v8.6.0.tar.gz
$ cd esmf-8.6.0/
$ ls
build  build_config  cmake  LICENSE  makefile  README.md  scripts  src

Starting by defining the location of the code 

$ export ESMF_DIR=$PWD

Running to get local information 

$ make info >& run_make_info.log


Launching the makefile in parallel: 

$ make -j8 lib >& run_make.log
$ tail run_make.log
(...)
ESMF library built successfully on Mon 13 May 2024 12:58:46 PM -03
To verify, build and run the unit and system tests with: make check
 or the more extensive: make all_tests

Verifying that installation worked fine 

$ make all_tests >& run_make_tests.log
$ $ cat run_make_tests.log  | grep failed
The following unit test files failed to build, failed to execute or crashed during execution:
Found 7800 non-exhaustive single processor unit tests, 7744 passed and 56 failed.

Downloading the Input data

All input data will be downloaded in 

/share/cesm

Input datasets are needed to run the model. CESM input data are available through a separate Subversion input data repository.

  • Change check_input_data header so it runs with Python 2.7.x version: 
sed -i -e 's!/usr/bin/env python!/share/anaconda2/bin/python!' ./cime/scripts/Tools/check_input_data
