Algorithm Acceleration from GPGPUs for the ATLAS Upgrade

Mostrar otras versiones (1)

Feasibility studies into the use of GPUs have been performed on two key algorithms in the ATLAS High Level Trigger. A GPU-based version of the Z-finder routine was found to give up to 35 times speedup in the best case scenario, while a speed-up of over 5 times was observed in a GPU-based Kalman Filte...

description Feasibility studies into the use of GPUs have been performed on two key algorithms in the ATLAS High Level Trigger. A GPU-based version of the Z-finder routine was found to give up to 35 times speedup in the best case scenario, while a speed-up of over 5 times was observed in a GPU-based Kalman Filter routine. The potential acceleration gained from using GPUs should be considered in order to handle the much higher data rates anticipated in future operation of the ATLAS detector.
