Aurora ESP: Simulating and Learning in the ATLAS Detector at the Exascale

A candidate event in which a Higgs boson is produced in conjunction with top and anti-top quarks which decay to jets of particles. The challenge is to identify and reconstruct this type of event in the presence of background processes with similar signatures which are thousands of times more likely. (Image: CERN)

Project Description

The ATLAS experiment at the Large Hadron Collider measures particles produced in proton-proton collision as if it were an extraordinarily rapid camera. These measurements led to the discovery of the Higgs boson, but hundreds of petabytes of data still remain unexamined, and the experiment’s computational needs will grow by an order of magnitude or more over the next decade. This project deploys necessary workflows and updates algorithms for exascale machines, preparing Aurora for effective use in the search for new physics.

Note: The original project PI Jimmy Proudfoot has retired.
