Activity since the last review (in these 15 months)
Construction of the CC-J at phase 1,2
- Phase 1 and 1/3 of Phsae 2 hardware installed
- High Performance Storage System (HPSS) with 100 TB Tape library
- CPU farm of 128 processors (about 4000 SPECint95)
- 3.5 TB Raid Disk , Two Gigabit Ethernet Switches, etc.
- A tape drive and a workstation installed at BNL RCF for tape duplication
- Software environment for PHENIX computing : established
- AFS local mirroring, Linux software environment, LSF etc : ready to use
CC-J operation
- CC-J started operation in June 2000.
- 40 userÅfs accounts created so far.
- 100 K event simulation (130 GeV/nucleon, Au+Au min. bias) of
- (1)retracted geometry, zero filed, (2) standard geometry, zero filed,
- (3)full 2D field field, (3) full 3D field,(3) half 3D filed : in progress
- Real raw data (2TB) of PHENIX experiment transferred to CC-J via WAN
- Large ftp performance (641 KB/s = 5 Mbps) was obtained (RTT = 170 ms)
- data analysis by regional users are in progress.
