Computing GRID

Beside the analysis of the data from experiments at Large Hadron Collider in CERN, it is most important what is the access to these data. At the present time is the access to the experimental data from LHC possible only in the framework of the computing grid WLCG (World LHC Computer Grid).

Due to Slovak Republic collaboration with CERN, the Slovak LHC Computing Grid SLCG was developed and successfully composed to the world computing grig WLCG hierarchy. There are two centers in Slovakia: one at the Faculty of Mathematics, Physics and Informatics, Comenius University in Bratislava and the second at the Institute of Experimental Physics, Slovak Academy of Sciences in Košice. These are most powerful computer farms at slovak scientific institutes, which have access to the huge computing capacity of the WLCG. Both centers are used on the same way by the ATLAS experiment and the ALICE experiment too.

The building up of the computing center at the Institute of Experimental Physics, Slovak Academy of Sciences in Košice and at the Faculty of Science, Pavol Jozef Šafárik University in Košice has been covered by: Ladislav Šándor, Dušan Bruncko, Pavol Stríženec and by technical experts: Miloš Straka, Ingrid Kuľková, Martin Vaľa, Richard Bílek, Marián Babik, Marián Zvada a Janka Vrláková.

The slovak computing centers SLCG are every year enlared and modernized. In the 2013 had the center in Košice 408 cores and 212 TB of memory. Since starting up in March 2013 it has computed 1.68 milion tasks. In present time to the Košice computing cluster also Technical University in Košice is contributing by 20 cores and 2 TB disc memory.
