Invited students participated in a hackathon, which was a coding event in which teams of developers ported their applications to run on GPUs, or optimized their applications that already run on GPUs. Each team consisted of two or more developers who are intimately familiar with (some part of) their application, and they work alongside one mentor with GPU programming expertise.
