GPU hackathons offer a unique opportunity for domain scientists and research software engineers to accelerate and optimize their applications on GPUs. Teams of researchers are paired with experienced GPU mentors to learn and apply the accelerated and parallel computing skills needed by the scientific community. Both current or prospective users of large hybrid CPU/GPU HPC clusters who develop applications that could benefit from GPU acceleration are encouraged to participate!

The ENCCS hackathon will be designed for teams to work in productive sprint sessions with expert mentors for a full week. A wide variety of different projects are possible, for example:

  • Accelerating applications written in common languages - C/C++, Fortran, Python
  • Using OpenACC to gradually offload work to GPUs and incrementally improving the performance
  • Identifying expensive kernels and porting them to CUDA
  • Profiling already GPU accelerated applications to find hotspots for further acceleration


Teams are expected to bring their own code or project to the event and be motivated to make progress during the hackathon. 
No advanced GPU skills required, but teams are expected to know the basics of GPU programming and profiling at the event. A collection of GPU lectures, tutorials, and labs are available for all participants at no fee. Please contact organizers for more information to help you prepare for the hackathon. 

GPU Compute Resource

Teams attending the event will be given access to a GPU cluster for the duration of the hackathon. If participants prefer they can use their own GPU resource at the event.

Event Format

The ENCCS GPU Hackathon will be hosted in Stockholm, Sweden with all times Central European Time (CET). 


Teams submit project proposals which are evaluated based on quality and feasibility. A call for proposals will be announced closer to the event. Invited teams are asked to register all participating team members and start preparing for the hackathon.

Attending the Hackathon

If your team is accepted for the hackathon, registration information will be provided along with mentor introductions and computational resource access. Accepted teams should:

  • Register all team members for the event.
  • Review the attendee guide.
