Distributed informational systems, HPCC

More than one thousand staff members of JINR and other research centres are the HPCC users. JINR HPCC (Fig. 3) is one of the ten largest Russian centres. It actively cooperates with other leading centres - Intergovernmental Supercomputer Centre, Institute of High-Performance Computations and Data Bases (St. Petersburg). In collaboration with the leading nuclear physics centres of Russia, JINR HPCC participates in creating the Russian Regional Centre for LHC Data Handling.

In 2001, the creation of the GRID segment in Russia was in progress. Ten more institutes of the Russian Federation take part in the project. The main LIT activity consists in the installation of GLOBUS toolkit, creation of common information server GRIS (Grid Resource Information Service) and GIIS (Grid Index Information Service), certification server creation, testing of metadispatcher, development of monitoring tools, data management, physical event mass generation and creation of a distributed database at the LIT PC-farm and HPCC servers.

During the year, SPP2000 server was used by 81 of 142 registered users. The CPU usage was 96 % and the total CPU time was 58500 hours. Table 3 shows the percentage of CPU time used by JINR Laboratories.

The Convex 220 computer was used as the computing, e-mail, and http-server by 1215 users, 1031 were active e-mail users. Table 4 shows the registered users distribution over the JINR Laboratories.

There is a plan to replace the old Convex computers with a cluster of Intel-based servers.
