GPU Compute

The Visualization and Computation group has a long history of working with cutting edge GPU compute. From the early beginnings with register combiners, through OpenGL shaders, to becoming a certified CUDA Research Center.


In the SCORE project we were responsible for GPU acceleration of the SPH simulations. In addition to this, we were heavily involved in the general SCORE code design and code development. The end result was an efficient GPU implementation supporting many complex simulations.

Simulation on GPU

Shallow water simulation is performed by solving a hyperbolic conservation law. These kind of simulations are perticularly suitable for GPU-based implementation, because they can be solved by using explisite schemes. We have therefore developed a highly optimized Cuda implementation.

Medical Ultrasound

Medical ultrasound machines use advanced signal and image processing to produce the best possible image quality. GPUs is the prefferred computational resource due to their flexibility and floating point performance. We help our industrial partner to make good design choises and optimize their algorithms.
