The GPU Science page is always pretty popular so I thought I'd thought I'd mention an upcoming event.

OLCF’s second OpenACC hackathon will take place the week of October 19th, 2015

The goal of each hackathon is for current or prospective user groups of large hybrid CPU-GPU systems to send teams of 3-6 developers along with either (1) a (potentially) scalable application that needs to be ported to GPU accelerators, or (2) an application running on accelerators which needs optimization. There will be intensive mentoring during this 5-day hands-on workshop, with the goal that the teams leave with applications running on GPUs, or at least with a clear roadmap of how to get there. Our mentors come from national laboratories, universities and vendors, and besides having extensive experience in programming with OpenACC, many of them develop the OpenACC-capable compilers and help define the OpenACC standard.

The application period is now open and closes on 3 July, 2015. Space will be limited to a maximum of eight teams, with two mentors for each team. Groups will be notified about acceptance or rejection of their application by Friday, July 31, 2015. See below how to apply. Prior GPU experience is not required! Those groups whose application successfully passes the selection process will receive further information regarding registration.
