This workshop will first focus on an entry-level GPGPU introduction by Robert Strzodka, followed by a discussion of hardware-efficient PDE solvers with applications in Image Processing. After a brief review of the current state-of-the-art of FEM codes on the CPU side, algorithmic design patterns for efficient GPU implementations will be experimentally evaluated. (Note: talks will be given in German.) http://www.mathematik.uni-dortmund.de/~goeddeke/workshop/index.html
