Computational infrastructure developed in the National Centre for Nuclear Research (NCBJ) within the framework of the CIS (Swierk Computing Centre) project will be used to process experimental data acquired at the "Large Hadron Collider beauty" (LHCb) experiment. Currently 63 teams from various laboratories all over the world, including NCBJ, comprising more than 600 scientists are involved in the experiment.
"The experiment is run at the LHC accelerator in CERN. This is just the accelerator that made possible to experimentally confirm existence of the Higgs particle - the 2013 Nobel prize in physics was awarded to theoreticians who had predicted the particle. The scientific objective is to search for physical phenomena beyond the Standard Model and to understand combined CP symmetry violation. In common speech it can be said that scientists will be trying to answer the question whether physical processes indeed run identically if all physical features are replaced by their mirror images. The commonly accepted theory of elementary interactions predicts that matter and antimatter should behave as mirror images of the sane entities",
explained Professor Wojciech Wislicki, CIS project Leader.
"The LHCb experiment ranks among the most important scientific endeavours of the present times. It should significantly help to explain the matter/antimatter asymmetry issue. Why the issue is so interesting? Without postulating such an asymmetry it is difficult to understand why the entire matter and antimatter in the early Universe did not annihilate, in other words why stars, planets and we humans do exist."
Resources and services set aside in CIS were used to organize a new Worldwide LHC Computing Grid (WLCG) centre. The centre was effectively made available to scientists working at the LHCb experiment on December 20, 2013. The set-aside infrastructure has been organized as a Tier-2D centre. Primary function of such a centre is to provide some fast and reliable storage for experimental data. Currently 100 TB of storage has been set aside for the Grid needs, the target level of 300TB is to be achieved in 6 months. Besides the storage, some CIS computing power - currently 320 nodes, about 1000 nodes in the future, some dedicated software, as well as necessary networking infrastructure - two independent fiber optic links each of 1 Gbit/s throughput - have also been set aside for the Grid.
