AMD GPU Hackathon

7 Mar 2023 • 09:00 - 16 Mar 2023 • 17:00 CET


About the event

Dardel is a Swedish flagship supercomputer operated by PDC at KTH in Stockholm. It is an HPE Cray EX system with AMD EPYC™ 64 core CPUs and AMD Instinct MI250X GPUs. Compute time on Dardel is available for academic research via NAISS.

This hackathon is for teams of research software developers who want to accomplish one or more of the following goals:

  • Port their code to run on AMD Instinct™ GPUs using a GPU programming framework like HIP, OpenMP, SYCL etc.
  • Improve the performance of a code that already runs on AMD Instinct™ GPUs.
  • Scale up their codes to multiple AMD Instinct™ GPUs.

During the hackathon, project teams will be paired up with expert mentors from HPEAMDPDC and ENCCS who will guide them during the hackathon to accomplish their stated goals. Teams should have at least two members who are prepared to work full-time on their projects for the duration of the hackathon. We furthermore also strongly encourage diversity in project teams.


This hackathon will take place over four days split over two weeks. The first day of the hackathon, March 7, will be online while the main work will be hosted on-site on KTH Campus at Drottning Kristinas väg 61, 114 28 in Stockholm, Sweden, on March 14-16.


  • Teams should consist of at least two, and preferably three, members who are ready to actively participate during the event.
  • Teams should know their application well and have the programming experience to modify the code.
  • Projects should be under an open-source license.

No advanced GPU skills are required, but it is helpful for teams to know the basics of GPU programming and profiling. Team members should get familiar with aspects of the AMD ROCm™ open software and the AMD HIP programming language (https://docs.amd.com/).

Compute Resource

Teams attending the event will be given access to the Dardel system ahead of the hackathon.

Project Submission

To apply for participation in this hackathon please describe your project in detail in the registration form below. Note that all team members should register and fill the “Personal information” section, but only one person in your team needs to fill the “Project description” section. Applications will be reviewed by an expert panel according to the following requirements:

  • The project team should consist of at least two members who know the code well.
  • Diversity in the project team.
  • The project should be described in sufficient detail and have well-defined goals for efficiency or for scaling up.
  • The code should have a significant impact (or large potential for significant impact) for a specific organisation or a wide community
  • The code should be open source. A link to the source code should be included in the application.
  • Projects should have a build system based on standard tools like Make or CMake, and teams should be prepared to compile the code on the Dardel system before the hackathon.
  • Availability of expertise needed to successfully support the project.

Ahead of the hackathon, accepted teams should be prepared to:

  • Go through learning resources on the AMD ROCm™ software ecosystem recommended by the organisers.
  • Make an effort to profile their code ahead of the hackathon for relevant input decks to identify performance critical code regions and possibly performance bottlenecks.
  • Be ready to (virtually) meet at least once with their expert mentor(s) to prepare for the hackathon.
  • Install, compile, and execute their application on Dardel to ensure that nothing is missing in the Dardel environment.
  • Commit to providing feedback to PDC/KTH local support team and expert mentors.
