João Pina is a computing researcher at LIP. He has a Ph.D. in Physics with research work in the ATLAS detector at the CERN Large Hadron Collider (LHC). He joined the LIP computing group as a post-doc researcher, to work on grid computing technologies acting as a contact point for the Portuguese LHC community. In 2013 joined the European Grid Infrastructure (EGI) and currently, he is responsible for the coordination of the EGI software stack and liaising between the several international development teams. He also is the Regional Contact Point for the EGI Spanish federation and National Infrastructure Liaison for Portugal. He participated in major e-infrastructure projects like EGI-Inspire and EOSC-Hub as well as in the WLCG and IBERGRID infrastructures. He is currently collaborating with the Portuguese National Distributed Computing Infrastructure (INCD) acting as a technical advisor.

Title: WLCG Computing and Big Data

Abstract: The Large Hadron Collider (LHC) experiments are located at CERN in Geneva Switzerland and are producing around 90 petabytes of data per year since the beginning of 2010. The data needs to be stored and made available for analysis to more than 12000 researchers spread across the globe. In order to achieve this, the Worldwide LHC Computing Grid (WLCG) project was created which aimed to develop, build, and maintain a global computing facility of more than 170 computing centers spread over 40 countries, linking up national and international grid infrastructures. Even though WLCG has been operating a distributed computing infrastructure for the past 15 years and currently most of the LHC computing resources are being provided by the classical grid sites, over the last years the LHC experiments have been using more and more public clouds and High-Performance Centers. Till talk will present the past, current, and future challenges of WLCG computing and how to handle one of the most emblematic Big Data challenges of today.
