The University of Maryland are sponsoring a GPGPU programming contest. All entries will be released under version 3 of the GPL at the conclusion of the contest. Contestants are asked to submit code for sparse matrix multiplication. UMD will be evaluating entries on both vector/sparse matrix and sparse matrix/sparse matrix multiplications, using a variety of different inputs. As the contest progresses, UMD will update the LeaderBoard regularly, so contestants will have some idea of where they stand. Contestants are welcome to make as many entries as they want, so submit early and then tweak your designs. Entries can be written in either GLSL or CUDA. Prizes include NVIDIA Quadro FX 5600 GPUs, sponsored by NVIDIA. (http://scriptroute.cs.umd.edu/gpucompete/)
