Summary
The construction of the PHENIX Computing Center in Japan (CC-J) at RIKEN Wako campus, which will extend over a three years period, began in April 1999.
The CC-J is intended as the principal site of computing for PHENIX simulation, a regional PHENIX Asian computing center, and a center for the analysis of RHIC spin Physics.
The CC-J will handle the data of about 220 TB/year and the total CPU performance is planned to be 10,000 SPECint95 in 2002.
CPU farm of 64 processors (RH5.2, kernel 2.2.11 with nfsv3 patch) is stable.
About 50 MB/s pftp performance was obtained for HPSS access.
Large ftp performance (641 KB/s = 5 Mbps) was obtained for a single ftp connection using a large TCP window-size (512 kB) over the Pacific Ocean (RTT = 170 ms)
Stress tests for the entire system were carried out successfully.
Replication of the Objectivity/DB over the WAN will be tested soon.
The CC-J operation will be started in April 2000.
