• Update example HPC module versions re: Compute Canada change to StdEnv/2020.

v21.1 (2021-10-21)

• Change memory per node for sbatch runs to 0 to ensure that jobs go on to the “by-node” queue on graham. The queue selection algorithm in the scheduler on graham appears to have changed (without announcement) on 13-Jul-2021 so that the previous memory per node of 125G now sends jobs to the “by-core” queue which is generally more crowded.

• Rename Git default branch from master to main.

• Change continuous integration from Bitbucket pipeline to GitHub Actions workflow. CI reports are at https://github.com/SalishSeaCast/NEMO-Cmd/actions Unit test coverage report visualization is at https://app.codecov.io/gh/SalishSeaCast/NEMO-Cmd

• Migrate from Mercurial on Bitbucket to Git on GitHub due to Bitbucket’s decision to terminate support for Mercurial. Repository is now at https://github.com/SalishSeaCast/NEMO-Cmd

• Expose nemo_cmd.prepare.record_vcs_revisions() function for use by packages like MOHID-Cmd that extend NEMO-Cmd.

• Enable version control system (VCS) revision recording for Git repositories: https://nemo-cmd.readthedocs.io/en/latest/run_description_file/3.6_yaml_file.html#vcs-revisions-section

• Replace namelist.py module with f90nml package.

• Change to new MOAD package layout.

v19.1 (2019-08-26)

• Add run description YAML file docs about land processor elimination option.

• Add Bitbucket continuous integration pipeline to run unit tests and generate unit tests coverage report.

• Drop support for Python 2.7; minimum version is now 3.5.

• Change to use black for code style management.

• Change to CalVer versioning convention. Version identifier format is now yy.n[.devn], where yy is the (post-2000) year of release, and n is the number of the release within the year, starting at 1. After a release has been made the value of n is incremented by 1, and .dev0 is appended to the version identifier to indicate changes that will be included in the next release. v19.1.dev0 is an exception to that scheme. That version identifies the period of development between the v1.3 and v19.1 releases.

1.3 (2019-01-20)

• Change to use python/3.7.0` module for `slurm workload manager`_ systems due to deprecation of ``python27-scipy-stack module on cedar.computecanada.ca and graham.computecanada.ca.

• Add support for --waitjob command-line option on systems that use slurm resource manager.

• Expose functions in nemo_cmd.prepare for use by packages like SalishSeaCmd that extend NEMO-Cmd:

  • nemo_cmd.prepare.add_agrif_files()

  • nemo_cmd.prepare.check_nemo_exec()

  • nemo_cmd.prepare.check_xios_exec()

  • nemo_cmd.prepare.copy_run_set_files()

  • nemo_cmd.prepare.get_hg_revision()

  • nemo_cmd.prepare.get_n_processors()

  • nemo_cmd.prepare.write_repo_rev_file()

• Fix bugs in the NEMO.sh script generation re: extra {} in some shell variable expressions.

• Drop support for NEMO-3.4.

• Fix a bug that caused prepare plug-in to fail for AGRIF runs that are not initialized from restart files.

• Add --no-deflate command-line option to exclude nemo-deflate from the NEMO.sh job script if you are using on-the-fly deflation in XIOS-2; i.e. you are using 1 XIOS-2 process and have the compression_level="4" attribute set in all of the file_group definitions in your file_def.xml file.

• Change temporary run directory names from UUID to run id concatenated to microsecond resolution timestamp.

• Exclude cliff-2.9.0 as a dependency due to OpenStack bug #1719465.

1.2 (2017-10-03)

• Add support for running on HPC systems that use the slurm workload manager; e.g. cedar.computecanada.ca and graham.computecanada.ca.

1.1 (2017-09-30)

• Change from ncks to nccopy as tool underlying the deflate plug-in to reduce memory footprint.

• Add support for the use of AGRIF (Adaptive Grid Refinement in Fortran) in NEMO-3.6 runs.

• Expand shell and user variables in namelist file paths.

• Use resolved repo path in VCS revisions recording message about uncommitted changes.

• Change to copy ref namelists to temporary run dir instead of symlinking them; facilitates easier run result archeology and reproducibility.

• Fix bug in atmospheric forcing file links checking function call.

1.0 (2017-04-27)

• Enable namelist.namelist2dict() to handle Fortran boolean values true and false (no leading/trailing dots).

• Confirm that the rebuild_nemo.exe executable in the prepare plug-in so that a run is not executed without it only to fail when the combine plug-in is run. See https://github.com/SalishSeaCast/NEMO-Cmd/issues/19.

• Add find_rebuild_nemo_script() to the API. See https://github.com/SalishSeaCast/NEMO-Cmd/issues/20.

• For NEMO-3.6 only, restart file paths/filenames are now specified in a new restart section instead of in the forcing section. See https://nemo-cmd.readthedocs.io/en/latest/run_description_file/3.6_yaml_file.html#restart-section.

• The existence of all paths/files given in the run description YAML file is confirmed. An informative error message is emitted for paths/files that don’t exist.

• Add optional filedefs item to output section of run description YAML file to facilitate the use of a file_Def.xml file with XIOS-2.

• Change spelling of keys in output section of run description YAML file:

  • files becomes iodefs

  • domain becomes domaindefs

  • fields becomes fielddefs

  Old spellings are retained as fall-backs for backward compatibility.

• Fix Python 2.7 Unicode/str issue in Mercurial version control revision and status recording. See https://github.com/SalishSeaCast/NEMO-Cmd/issues/16.

• Add option to provide in the run description YAML file a list of PBS resource key-value pairs to produce #PBS -l directives for in the run shell script. See https://nemo-cmd.readthedocs.io/en/latest/run_description_file/3.6_yaml_file.html#pbs-resources-section, and https://github.com/SalishSeaCast/NEMO-Cmd/issues/10.

• Add option to provide in the run description YAML file a list of HPC environment modules to include module load commands for in the run shell script. See https://nemo-cmd.readthedocs.io/en/latest/run_description_file/3.6_yaml_file.html#modules-to-load-section, and https://github.com/SalishSeaCast/NEMO-Cmd/issues/11.

• Add the option to use absolute paths for coordinates and bathymetry files in the run description YAML file. See https://nemo-cmd.readthedocs.io/en/latest/run_description_file/3.6_yaml_file.html#grid-section, and https://github.com/SalishSeaCast/NEMO-Cmd/issues/5.

• Add nemo_cmd.fspath(), nemo_cmd.expanded_path(), and nemo_cmd.resolved_path() functions for working with file system paths. See https://nemo-cmd.readthedocs.io/en/latest/api.html#functions-for-working-with-file-system-paths.

• Port in the SalishSeaCmd run plug-in in a minimal form sufficient for use on TORQUE/PBS systems that don’t require special PBS feature (-l) directives, or loading of environment modules.

• Add optional recording of revision and status of Mercurial version control repositories via a new vcs revisions section in the run description YAML file.

• For NEMO-3.6 only, enable the use of ref namelists from directories other than from CONFIG/SHARED/. The default is to symlink to CONFIG/SHARED/namelist*_ref when there are no namelist*_ref keys in the namelists section of the run description YAML file.

• Change from using pathlib to pathlib2 package for Python 2.7 because the latter is the backport from the Python 3 stdlib that is being kept up to date.

• Refactor the combine plug-in to only run rebuild_nemo to combine per-processor results and/or restart files.

• Add deflate plug-in to deflate variables in netCDF files using Lempel-Ziv compression.

• Fix a bug whereby results directories were gathered with a redundant directory layer; e.g. the files in runs/9e5958d4-cb95-11e6-a99b-00259059edac/restart/ were gathered to results/25dec16/restart/restart/ instead of results/25dec16/restart/.

0.9 (2016-12-30)

• Use tox for unified Python 2.7 and 3.5 testing.

• Refactor the gather plug-in in a minimal form sufficient for use by the GoMSS_Nowcast package.

• Refactor the prepare plug-in as the first nemo subcommand.

• Add token-based Fortran namelist parser from gist.github.com/krischer/4943658. That module also exists in the tools/SalishSeaTools package. It was brought into this package to avoid making this package depend on SalishSeaTools.

• Adopt yapf for code style management. Project-specific style rules are set in .style.yapf.

• Initialize project from the SalishSeaCmd/ directory of the tools repo with:

  hg convert --filemap tools/NEMO-Cmd_filemap.txt tools NEMO-Cmd
  

  A copy of NEMO-Cmd_filemap.txt is included in this repo.
