cerulean 1.0.0

A Python library for talking to HPC clusters and supercomputers

Cerulean

Cerulean is a Python 3 library for talking to HPC clusters and supercomputers. It lets you copy files between local and SFTP filesystems using a pathlib-like API, it lets you start processes locally and remotely via SSH, and it lets you submit jobs to schedulers such as Slurm and Torque/PBS.

Documentation and Help

Cerulean can be installed as usual using pip:

pip install cerulean

Instructions on how to use Cerulean can be found in the Cerulean documentation.

Code of Conduct

Before we get to asking questions and reporting bugs, we’d like to point out that this project is governed by a code of conduct, as described in CODE_OF_CONDUCT.rst, and we expect you to adhere to it. Please be nice to your fellow humans.

Questions

If you have a question that the documentation does not answer for you, then you have found a bug in the documentation. We’d love to fix it, but we need a bit of help from you to do so. Please do the following:

1. use the search functionality here to see if someone already filed the same issue;

2. if your issue search did not yield any relevant results, make a new issue;

3. apply the “Question” label; apply other labels when relevant.

We’ll answer your question, and improve the documentation where necessary. Thanks!

Bugs

Like most software, Cerulean is made by humans, and we make mistakes. If you think you’ve found a bug in Cerulean, please let us know! Reporting bugs goes as follows.

1. Use the search functionality here to see if someone already filed the same issue.

2. If your issue search did not yield any relevant results, make a new issue. Please explain: - what you were trying to achieve, - what you did to make that happen, - what you expected the result to be, - what happened instead. It really helps to have the actual code for a simple example that demonstrates the issue, but excerpts and error messages and a description are welcome too.

3. Finally, apply any relevant labels to the newly created issue.

With that, we should be able to fix the problem, but we may ask for some more information if we can’t figure it out right away.
