Documentation, best practices, and tutorials that are focused on making the most out of HPC resources via ECP CI enhancements. As such, information presented here is centred on those HPC focused enhancements made to to GitLab. We will make ample reference to GitLab’s official documentation and strongly encourage you to look there for details not covered in these pages. For any questions on runner or server deployment please see the administrator documentation.

Continuous Integration

Understanding the GitLab Runner is the key to making full use of the GitLab CI ecosystem. These sections are targeted not just at those unfamiliar with using the GitLab runner but anyone who wishes to understand how the ECP CI enhancements will affect their CI jobs.
