A special workshop dedicated to “GPGPU: Methods, algorithms and applications” will be hosted in conjunction with the 6th International Conference On Computational Science (ICCS 2006). The primary goal of this session is to present the GPU as a powerful parallel processor. Contributions presenting novel, original work in all areas of GPGPU, e.g. from hardware abstractions to specific applications, are cordially invited. For more information, please refer to the official workshop web page.
