Second Place at SBAC-PAD/WSCAD Marathon of Parallel Programming 2017

25/10/2017 20:34

The LaPeSD/UFSC team (Alyson Pereira, Emmanuel Podestá Jr. and Bruno Marques) is the 2nd-place Winner of the Marathon of Parallel Programming, which was held in conjunction with International Symposium on Computer Architecture and High Performance Computing (SBAC-PAD) and Simpósio em Sistemas Computacionais de Alto Desempenho (WSCAD) in Campinas/SP.

Each team consists of three students members and a coach. They have about 5 hours to solve up to 9 problems. For Local Contest, the teams can also bring printed hard copy material (e.g. books, manuals, notes, papers). Judgment is strict. In the beginning of the contest, teams receive problem descriptions and sequential (serial) solutions. Resolution involves not only the correct problem solution but also performance speedup for parallel (or distributed) version, measured according to criteria defined by committee for current contest.
