The FASER experiment is an LHC experiment located in a tunnel parallel to the LHC ring and is considerably smaller and low-budget compared to the titan LHC experiments such as ATLAS and CMS. The experiment seeks to detect new long-lived particles that have travelled half a kilometer from a LHC proton-proton collision site, escaping the major ATLAS experiment undetected. The only other proton collision “background” particles reaching FASER’s faraway location are muons and neutrinos. Evidence of a new particle, such as the hypothetical dark photon, may lead to answering our most fundamental questions of the Universe such as the origin of dark matter.

Ganga is a computational task-management tool, which allows for the specification, submission, bookkeeping and post-processing of computational tasks on a wide set of distributed resources. Ganga has been developed to solve a problem increasingly common in scientific projects, which is that researchers must regularly switch between different processing systems, each with its own command set, to complete their computational tasks. Ganga provides a homogeneous environment for processing data on heterogeneous resources.

The Patatrack project started in 2016 by a group of people with various area of expertise, such as software optimization, heterogeneous computing, track reconstruction and High Level Trigger (HLT) at the CMS experiment at CERN. The goal was to demonstrate that part of the HLT reconstruction could be efficiently offloaded on machines equipped with GPUs for parallel execution. Nowadays, Patatrack developments have been integrated into the CMS software for event reconstruction and the project focuses on the exploration of innovative software and hardware technologies to bring smart software closer to the detector read-out at CERN experiments.
