GROMACS is a molecular simulation kit, which can do all kinds of "soft matter" simulations such as nanotubes, polymer chemistry, zeolites, adsorption studies, proteins, and more. It is being used by researches worldwide and is one of the bigger bio-informatics softwares around. Until now only CUDA was being used. To make it possible to use other accelerators, Stream Computing ported GROMACS to OpenCL. The folks at Stream Computing are looking for help on this project.
