ALICE experiment is one of four experiments involved in the study of processes of hadrons and nuclei collisions at the highest energies of the modern accelerator.
Timely and statistically sufficient analysis of data recorded in such collisions is possible only under the processing of real and simulated data in a heterogeneous and geographically distributed computing environment.
Back in 2004, during mass generating of physical events and transferring the data to CERN and other computing centers, the JINR CICC took part in the debugging of basic ideas of ALICE distributed computing in the frames of ALICE grid Environment (AliEn).
From 2004 to the present days CICC took and currently takes part in installation and support of a specific package for managing the recording and reading of xrootd data necessary for the successful and stable operation of the ALICE experiment. Stable and reliable operation of the CICC provides a constant and significant contribution in the total number of analyzed and simulated events throughout the ALICE experiment.
At the CICC were tested repeatedly both new packages under development and the middleware, adopted for the use at ALICE(CREAM-CE and testing of the interface between the application software and VO-box-middleware )
Besides providing ALICE grid activities, the CICC is actively involved in supporting of a local small test cluster to analyze LHC data in the PROOF parallel computing system.

The results of the use of the CICC in the ALICE experiment were reported in all international conferences
“Distributed Computing and Grid Technologies in Science and Education” held at JINR from 2006 every two years, at international conferences,
ACAT (Advanced Computing and Analysis Techniques in Physics Research),
CHEP (Computing in High Energy and Nuclear Physics) and the
Conferences of Young Scientists and Specialists at JINR.
