Abstract

The Large Hadron Collider (LHC) is one of the largest and most complicated scientific apparata ever constructed. The detectors at the LHC ring see as many as 800 million proton-proton collisions per second. An event in 10 to the 11th power is new physics and there is a hierarchical series of steps to extract a tiny signal from an enormous background. High energy physics (HEP) has long been a driver in managing and processing enormous scientific datasets and the largest scale high throughput computing centers. HEP developed one of the first scientific computing grids that now regularly operates 750k processor cores and half of an exabyte of disk storage located on 5 continents including hundred of connected facilities. In this talk, I will discuss the challenges of capturing, storing and processing the large volumes of data generated at CERN. I will also discuss how these challenges will evolve towards the High-Luminosity Large Hadron Collider (HL-LHC), the upgrade programme scheduled to begin taking data in 2026 and to run into the 2030s, generating some 30 times more data than the LHC has currently produced.

Speaker: Maria Girone

CTO @CERNopenlab

Maria has a PhD in particle physics. She also has extensive knowledge in computing for high-energy physics experiments, having worked in scientific computing since 2002. 

Maria has worked for many years on the development and deployment of services and tools for the Worldwide LHC Computing Grid (WLCG), the global grid computing system used to store, distribute, and analyse the data produced by the experiments on the Large Hadron Collider (LHC). 

Maria was the founder of the WLCG operations coordination team, which she also previously led. This team is responsible for overseeing core operations and commissioning new services.

Throughout 2014 and 2015, Maria was the software and computing coordinator for one of the four main LHC experiments, called CMS. She was responsible for about seventy computing centres on five continents, and managed a distributed team of several hundred people.
