License information

The cotainr package is disributed under the European Union Public License 1.2, a copy of which can be found in the LICENSE file in the cotainr GitHub repository.

User documentation

Extensive user documentation for cotainr is available on ReadTheDocs. There is also some LUMI-specific information on the Singularity page in the main LUMI documentation.

The cotainr package is developed by the LUMI consortium member DeiC (Denmark).

Several modules are available on LUMI, depending on the environment that you're using:

  • In CrayEnv the cotainr modules will use whatever version of cray-python is the default, which depends on other modules you may have loaded and can also change after system updates.
  • In LUMI software stacks the version of cray-python that matches the version of the software stack will be used. This is also reflected in the version part of the name of the module.

Pre-installed modules (and EasyConfigs)

To access module help and find out for which stacks and partitions the module is installed, use module spider cotainr/<version>.
