  • free-price-finnish-academics.
  • free-price-others.
The fee covers all materials, lunches as well as morning and afternoon coffees.
Teams can apply using the registration form. Each member of the team needs to register, and the team leader needs to fill in all fields in the registration form. Based on the applications at most six teams will be selected, with the aim of maximizing impact of the hackathon. Teams will be informed 1 week after the registration deadline if they have been accepted.
Additional Information


CSC is in collaboration with Nvidia and the E-CAM European HPC center of Excellence arranging a 3-day GPU hackathon. The GPU hackathon is a coding event in which teams of developers port their applications or kernels to run on GPUs, or optimize their applications that already run on GPUs. In particular the hackathon focuses on applications that can scale up to  multiple GPU nodes.

We are looking for teams of 3-4 developers. Collectively the team should know the application intimately. Please keep in mind that we are looking for teams with plans to develop GPU code – not to just run their code on GPUs. During the hackathon each team is supported by one mentor with in-depth GPU programming expertise.

At CSC the new Puhti-AI partition provides 80 nodes with 4 NVidia Volta GPUs each. This system provides in total more than 2 petaflops of performance.  This system is available during the course and accepted teams will also have access to the system beforehand to do some initial porting of the applications to Puhti.


This event helps the teams to jumpstart acceleration or optimization of their code on GPUs. By the end of the event each team should have their code running on GPUs, or at least have a clear roadmap of how to get there.


Basic level of GPU programming proficiency is enough. If the team members do not know GPU programming, they should attend the OpenACC course that is arranged at CSC during Monday and Tuesday the same week (  The participants should also be familiar with HPC programming in general,  and in using clusters and supercomputers.

There are a variety of tools available to program GPUs (e.g. CUDA, OpenACC, OpenMP4.5+, etc.) and we encourage you to explore the best one for your needs.
