The aim of the GAP project is the deployment of Graphic Processing Units (GPU) in real-time applications, ranging from high-energy physics online event selection (trigger) to medical imaging reconstruction. The final goal of the project is to demonstrate that GPUs can have a positive impact in sectors different for rate, bandwidth, and computational intensity.

ALICE (A Large Heavy Ion Experiment) is one of four major experiments at the Large Hadron Collider (LHC) at CERN.
The ALICE High Level Trigger (HLT) is a cluster of 200 nodes, which reconstructs collisions as recorded by the ALICE detector in real-time.
It employs a custom online data-transport framework to distribute data and workload among the compute nodes.
ALICE employs subdetectors...

Oral presentation
Significant new challenges are continuously confronting the High Energy Physics (HEP) experiments at the Large Hadron Collider (LHC) at CERN. The quest for rare new physics phenomena leads to the evaluation of a Graphics Processing Unit (GPU) enhancement for the existing high-level trigger (HLT), made possible by the current flexibility of the trigger system, which not only provides faster and...

The LHC will collide protons in the ATLAS detector with increasing luminosity through 2016, placing stringent operational and physical requirements to the ATLAS trigger system in order to reduce the 40 MHz collision rate to a manageable event storage
rate of 1 kHz, while not rejecting interesting physics events. The Level-1 trigger is the first rate-reducing step in the ATLAS trigger system...

The LHCb trigger system consists of a hardware level, which reduces the event rate of 30 MHz of inelastic collisions to 1 MHz, at which the detector is read out. In the subsequent High Level Trigger, based on a farm of PCs, the event rate is reduced to a level that can be stored and processed offline. For Run-II, the system has been upgraded such that the output of the first stage of the HLT...
