These files, that should be automatically created, are not being written:

  +
  +
In the case directory one has the file <CODE>Buildconf/cismIOconf/cism.buildIO.csh</CODE>, with the following content:
  +
<PRE>
  +
(...)
  +
# create new _io.F90 file using CISM's python script

  +
$PYTHON generate_ncvars.py $file_varsdef ncdf_template.F90.in

  +
It is looking for the environment variable that holds <CODE>python</CODE>. In the root directory of CESM the file <CODE>components/cism/bld/cismIO/README.cismIO</CODE>:
  +
<PRE>
  +
This directory and its scripts are intended to allow the user to change IO fields from the CISM code. The CISM IO files, *_io.F90, are
  +
auto-generated and typically difficult to modify. However, the corresponding variable definition files, *_vars.def, are easily modified
  +
and the IO files can be re-generated by running the cism.buildIO.csh script contained in this directory.
  +
  +
Usage of this script requires that the user has defined an enviroment variable PYTHON pointing to a local version of python, After that,
  +
the user simply runs the enclosed cism.buildIO.csh script, which runs a python script on each

  +
</PRE>
  +
Therefore I need to find where the <CODE>PYTHON</CODE> is defined within the <CODE>cime/config/cesm/machines/config_*.xml</CODE> files, or I defined it manually. It does not work it is defined previously the execution:
  +
<PRE style="shell">
  +
$ export PYTHON=/usr/bin/python3
  +
$ echo $PYTHON
  +
/usr/bin/python3
  +
$ ./case.build --clean
  +
$ ./case.build
  +
</PRE>
  +
Therefore, it is defined within <CODE>Buildconf/cismIOconf/cism.buildIO.csh</CODE> (must be defined in the template of this shell script!!). Looking in <CODE>$ROOTCESM</CODE> into <CODE>components/cism/source_cism/utils/build/generate_ncvars.py</CODE>, it is using python2! hydra does not support python2.

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:

$ 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

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

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)

Python error 

/usr/bin/env: ‘python’: No such file or directory

Fixed by imposing python3 

$ cp create_newcase create_newcase_orig
$ diff create_newcase create_newcase_orig
1c1
< #!/usr/bin/env python3
---
> #!/usr/bin/env python

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

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:

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

Looking for errors: 

$ tail run_case-setup.log
You can now run './preview_run' to get more info on how your case will be run

Which provides the following configuration: 

$ ./preview_run >& run_preview_run.log
$ cat run_preview_run.log 
CASE INFO:
  nodes: 6
  total tasks: 768
  tasks per node: 128

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 cime/scripts folder and change it everywhere: create_clone, create_newcase, create_test, query_config, query_testlists

Modify all the python scripts within cime/scripts/Tools 

$ cp -R Tools Tools_orig

These files, that should be automatically created, are not being written: 

bld/glc/fortran_autogen_srcs/glide_io.F90
bld/glc/fortran_autogen_srcs/glint_io.F90

In the case directory one has the file Buildconf/cismIOconf/cism.buildIO.csh, with the following content: 

(...)
   #  create new _io.F90 file using CISM's python script
   #
---------------------------------------------------------------------------
   $PYTHON generate_ncvars.py $file_varsdef ncdf_template.F90.in

It is looking for the environment variable that holds python. In the root directory of CESM the file components/cism/bld/cismIO/README.cismIO: 

This directory and its scripts are intended to allow the user to change IO fields from the CISM code.  The CISM IO files, *_io.F90, are
auto-generated and typically difficult to modify.  However, the corresponding variable definition files, *_vars.def, are easily modified
and the IO files can be re-generated by running the cism.buildIO.csh script contained in this directory.

Usage of this script requires that the user has defined an enviroment variable PYTHON pointing to a local version of python,  After that, 
the user simply runs the enclosed cism.buildIO.csh script, which runs a python script on each
(...)

Therefore I need to find where the PYTHON is defined within the cime/config/cesm/machines/config_*.xml files, or I defined it manually. It does not work it is defined previously the execution: 

$ export PYTHON=/usr/bin/python3
$ echo $PYTHON
/usr/bin/python3
$ ./case.build --clean
$ ./case.build

Therefore, it is defined within Buildconf/cismIOconf/cism.buildIO.csh (must be defined in the template of this shell script!!). Looking in $ROOTCESM into components/cism/source_cism/utils/build/generate_ncvars.py, it is using python2! hydra does not support python2.

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
