Advanced Resource Connector Soft- ware for ATLAS and LHC computing

Coordinating university or institute

Lund University,



Project description

ATLAS is the biggest instrument at the biggest machine on Earth, the Large Hadron Collider (LHC). It is 46 meters long and weighs 7000 tonnes, working like a huge camera, taking very detailed “pictures” of particle collisions. With a spacial resolution of microns, the raw size of one “picture” is 1.6 Mbytes, and with data taking rates of Megahertzs, it collects several Petabytes of raw data a year. The challenge is to store this data, process it to create samples ready for analysis, and to make it available to physicists around
the world in real-time. No single supercomputer exists meet this challenge, so the solution is to use the global network of supercomputers, for which our team develops software.
