What is JUBE?

The JUBE benchmarking environment provides a script-based framework for easily creating benchmark and workflow sets, running those sets on different computer systems, and evaluating the results. It is actively developed by the Juelich Supercomputing Centre. It focuses on managing the complexity of combinatorial benchmarks and ensuring reproducibility of the benchmarks. JUBE provides support for different workflows and the ability to use vendor-supplied platform configurations. The benchmark configuration and scripts can be specified in either YAML or XML format. JUBE is primarily designed for use on supercomputers with scheduding systems like Slurm or PBS, but also works on laptops running Linux or MacOS operating systems.

Documentation

JUBE is not (yet) available on pypi (it is work in progress). The source code can be downloaded from any of the following places:

• GitHub
• JSC JUBE Webpage

JUBE can be installed using pip or setup.py and needs python 3.2 or higher. You will also need SQLite version 3.35.0 (or higher) to use the database as a result output. Installation instructions can be found here.

The documentation for JUBE is split into Beginner Tutorial, Advanced Tutorial, FAQ, CLI, and Glossary and can be found in the User Guide.

In addition to the documentation, there are also tutorial examples which are described in the tutorials of the user guide and benchmark examples, which are curated examples of JUBE benchmarks (the latter will be either replaced or updated/extended soon).

For more information on the design and architecture of JUBE, please refer to this paper.

Community and Contributing

JUBE is an open-source project and we welcome your questions, discussions and contributions. Questions can be asked directly to the JSC JUBE developers via mail to jube.jsc@fz-juelich.de and issues can be reported in the issue tracker. We also welcome contributions in the form of pull requests. Contributions can include anything from bug fixes and documentation to new features.

JUBE development is currently still taking place on an internal GitLab instance. However, we are in a transition phase to move development to GitHub. The complete move will take some time. In the meantime, we will decide individually how to proceed with Pull Requests opened on GitHub. Before you start implementing new features, we would recommended to contact us, as we still have several open branches in GitLab.
