WhiteArea lectures' twiki HERE

The use of accelerators, in particular of Graphic Processing Units (GPUs), in High Performance Scientific Computing is growing very fast since few years.

GPUs have brought desktop and laptop computers to the Terascale (i.e. bringing computational power beyond a Teraflop), clusters to the Petascale and, in the foreseeable future, supercomputers to the Exascale.
A brief introduction about the GPU architecture and the CUDA programming language will be given.
A review and outlooks of the applications of the GPU technology in the field of High Energy Physics will be discussed as well.
 

For participants interested in the Kalman Filter and tracking performance on accelerators (using OpenCL), Felice provided the link to a talk by Ivan Kisel at the GPU workshop in Pisa in September:
