Title: GPULib: Accelerating Scientific Applications with Graphics Processing Units (GPUs)

Time: Tue, Mar 16, 2010, 2:00pm

Place: GFZ, Telegrafenberg, building H, lecture hall

The increasing temporal, spatial and spectral resolution of imaging sensors and the complexity of data analysis algorithms requires an unprecedented amount of processing power. The demand for highly realistic 3D graphics in computer games has resulted in the development of high-performance processors, so called graphics processing units (GPUs). These chips are fully programmable floating-point processors with a tremendous processing performance and huge memory bandwidth. Being a mass market product, these processors come at a fairly low price, which makes them attractive as floating-point accelerators for scientific computing and data analysis tasks. Unfortunately, exploitation of the processing performance requires fairly low-level software development. Luckily, software tools like GPULib ( provide an environment that enables scientists and researchers to take advantage of GPUs from within very high-level languages like IDL or MATLAB. In this presentation, I will review the basics of GPU computing and then introduce GPULib as a tool to accelerate GPU development. Using examples from remote sensing and signal processing, we will see the potential benefit of GPUs for a broad range of applications.
