Overview: Back End System
¥event building system (QUAD SMP and corresponding software supporting multiprocessor and multithreaded environment) will be upgraded; new event building will be performed in 2 stages: 7 builders at first stage (6 sectors and central detectors) and final building at second stage; QUAD- or 8-CPU-machines similar to existing one will be sufficient; software development is required to support multistage building
¥event recording system (QUAD SMP, RAID system and corresponding software) will be reused or upgraded if necessary
¥networking system: some improvements will be done to increase bandwidth and the number of clients
