Presentation

Making HPC software easy to install on multiple supercomputers or different architectures is a difficult task: different systems have different compilers, libraries, system commands etc. This task can be helped by tools like CMake and GNU Autotools.

In this Hackathon, we will help code developers better understand how to use these build systems to improve the portability of their applications. In addition, well-done configuration scripts facilitate the packaging of the software, and presentations will be given to propose different packaging possibilities to distribute the software.

This Hackathon is a multi-day virtual event targeting students, engineers and researchers developing HPC open-source software. It aims at helping teams of one to six developers improve the build scripts of codes they develop. The supported build systems for this Hackathon are Autotools and CMake.

You can now look again at the plenary presentations.

Prerequisites

Participants are expected to come with a code they develop. They should agree to share their source code with all the other participants. Therefore an open-source license (GPL, BSD, MIT, …) is required. This event will take place with Zoom, and a Slack space will be used for communicating between teams.

Event format

The TREX Build System Hackathon will be hosted online with all times Central European Summer Time (CEST). Teams will be assigned to virtual breakout rooms to work on their codes and will present their progress to all participants in the main virtual meeting space.

Registration

Registration is free. All team members should register for the event.

Application deadline: 28 October 2021 - CLOSED.

If you couldn't attend the event, or if you want to rewatch it, below you can find the recordings.
