Témata: HIGH performance computing, DATA compression, SCIENTIFIC computing, SOFTWARE frameworks, ELECTRONIC data processing
Abstrakt: Due to the increase of data volumes expected for the LHC Run 3 and Run 4, the ALICE Collaboration designed and deployed a new, energy efficient, computing model to run Online and Offline O 2 data processing within a single software framework. The ALICE O 2 Event Processing Nodes (EPN) project performs online data reconstruction using GPUs (Graphic Processing Units) instead of CPUs and applies an efficient, entropy-based, online data compression to cope with Pb–Pb collision data at a 50 kHz hadronic interaction rate. Also, the O 2 EPN farm infrastructure features an energy efficient, environmentally friendly, adiabatic cooling system which allows for operational and capital cost savings. [ABSTRACT FROM AUTHOR]
