Overview: Back End System
levent building system (QUAD Opteron-based machine 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
levent recording system (SUN Sparc SMP, RAID system and
corresponding software) will be replaced
by faster machine and disks to process increased data rate
lnetworking system: some improvements will be done to
increase bandwidth and the number of clients
