Description
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.
In the field of high energy physics, several groups are pursuing the use of GPUs for data analysis ( such as Maximum Likelihood fit inside the RooFit) and for Monte Carlo simulations of particle interactions inside the Geant4 framework.
The use of GPUs presented in this seminar is different: GPUs are employed for taking decisions in a trigger system, both as coprocessors in high level software trigger or "embedded" in real-time, fixed-latency hardware trigger.
