Version 1.17

Updates

Modified on: 2025-05-16

Summary

This release consists mostly of updated and new software being added to the eRN. Other important changes are related to autocomplete of included utilities and projects. Autocomplete for bat, rclone, and pet is enabled if bash completions is available. A hierarchy of projects can be created in a directory tree. This allows for subdirectories to use a parent project's configuration but use different environment variables, modules, and scripts. Prefixing module names with a - in the project configuration unloads the modules. The project hierarchy is always mirrored when running a job using the scratch.

Version 1.18

Updates

Modified on: 2025-06-13

The CUDA_VISIBLE_DEVICES environment variable may not always be set by the queue manager or the user.

Version 1.16

Updates

Modified on: 2025-05-16

Summary

The modules for BBTools, RAxML, Roary, and Salmon package updated versions of the software. Added grex to aid in the creation of regular expressions.

Documented new features and included more examples. Use a custom prompt in the shell, the features to be documented. ern jobs submit prevents submitting new jobs, using --inplace, if jobs have been previously submitted, in the working directory. The warnings when running software in interactive sessions, are now less intrusive, and is only shown if the resources are less than the recommended minimum.

Version 1.10

Updates

Modified on: 2025-04-03

Summary

All default settings have been moved to a configuration file, ~/ern/environments/deploy/config/ern.yaml. Users can override the defaults using the provided ern commands or editing ~/ern/var/config/ern.yaml.

Creating project configuration often displayed errors that could be safely ignored. The ern project commands have been improved to force a direnv reload only when:

  • the project configuration changes.
  • the project is enabled.

The original submit command no longer functions, please follow the instructions provided to make use of ern jobs submit. While loading a PBS cluster configuration, the existence of the host key in the known_hosts file is checked, and the key is added if it does not exists.

Two tools that could be generally useful are:

  • just is a handy way to save and run project-specific commands.
  • sd is similar to sed with performance and usability improvements.

Version 1.5

Updates

Modified on: 2025-03-04

Summary

The optional dependencies pyvista and pyg4ometry of GATE is included in gate/1.1_0d55cd4. A new conda environment is created when the module is loaded.

Shell integration is enabled for several utilities, such as: fzf, procs, btm, and hyperfine. The fzf integration is notable since Ctrl+R enables fuzzy searches of the history. Many of the included utilities were updated, the impact to users should be limited since most are used during development.

Several utilities were added to improve the user experience:

  • To calculate code metrics see scc.
  • To list files much like ls but with improvements, see eza.
  • To search for files, similar to find but faster, see fd.
  • To search through the content of files, similar to grep but faster, see rg.
  • For advanced users, to navigate directories, find files and launch commands, see broot
  • For advanced users, to edit files, see nvim.

In preparation for future improvements, several utilities were added, namely: duckdb, fq, yq, and rush. The kitty terminal and a collection of monospaced fonts were added. Eventually, the configuration should support graphics in broot, icons in for example broot and eza, mathematics glyphs, and coding fonts.

Summary

Two applications are added as modules chopper and NanoFilt. Updated versions of BEAST 1 and 2 are available. Previously created PBS cluster configurations are automatically updated to detect and gracefully handle network and authentication errors.

Version 1.1

Updates

Modified on: 2024-12-11

Summary

Packaged version 0.8.3 of dorado, and added version 4.1.7p1 of repeatmasker for testing. Many improvements, fixes, and documentation updates related to the ern command. Run ern changelog read for the details.

Migration and update notes

Changes to the submit command requires user actions.

OpenMPI

MPI should work out of the box when eRN software is run under mpirun. The environment variable ERN_ENABLE_MPI is no longer used.

Submitting jobs

The submit command is replaced by ern jobs submit, the old command remains available for the time being. Most arguments remain the same. The --profile argument is removed, instead create a cluster configuration by running:

1
ern cluster create --name=hpc --head-node=login.hpc.ufs.ac.za --node-select=ern         --email-address=<replace with your email address>

Creating a cluster configuration only needs to be done once. Load the cluster configuration before running ern jobs submit, or add the --cluster=hpc argument to the ern jobs submit command.

1
module load cluster/hpc

To submit GPU jobs load the cluster configuration as shown below:

1
module load cluster/hpc node_select=ern_gpu

An --mpi argument is added to submit MPI jobs, the generated script runs the command under mpirun, for example:

1
ern jobs submit --mpi --name=18SBayes --threads=24 --memory=64gb --hours=100         --input=aligned.nex --module=mrbayes --command=mb-mpi -- aligned.nex

Therefore, a separate script is no longer needed simply to run commands under MPI.
