The 8th AICS International Symposium 7 Feb,2018
"Invited talk: Toward Exabyte ~ A Challenge of Energy Frontier Particle Physics Experiments"
The world largest particle accelerator LHC (Large Hadron Collider) has been in operation since 2009 and ATLAS and other three experiments have been accumulating unpreceded amount of experimental data, which is now approaching the Exabyte scale. In order to process the data, a globally distributed computing infrastructure, the worldwide LHC computing grid (WLCG), has been developed and deployed among more than 150 sites from 35 countries. Even only for the ATLAS experiment, 300PB of data are recorded and 500,000 CPU cores are used for their processing, on the WLCG infrastructure. The University of Tokyo has been contributing to the WLCG infrastructure from the beginning as a key site in the Asia-Pacific region. In the upgrade program of LHC, expected amount of data to be generated will be 100 times more than now and a substantial evolution is required to satisfy the requirement. Many R&D programs have been started to achieve the evolution. In this presentation, the overview of the LHC experiments and WLCG, the contribution of Tokyo, and the upgrade plan will be discussed.
