1. Oct. 6, 1999PHENIX Comp. Mtg.1 CC-J: Progress, Prospects and PBS Shin’ya Sawada (KEK) For CCJ-WG

2. Oct. 6, 1999PHENIX Comp. Mtg.2 Current Configuration SUN E450 –2 x 400MHz CPUs –0.3GB work disk Linux farms (Alta Cluster) –32 CPUs (16 nodes) with memory of 128MB/cpu –Pentium II 450MHz: 18.5 SPECint95/cpu HPSS –100TB tape robot –5 SP2 servers Network: Gigabit ethernet and HiPPI

3. Oct. 6, 1999PHENIX Comp. Mtg.3 Performance Test PHENIX software Pftp between Linux nodes and HPSS –~50MB/s total with ~100% CPU usage of disk serers

4. Oct. 6, 1999PHENIX Comp. Mtg.4 AFS Arla vs Transarc AFS client –Arla is still very unstable from test results at CC-J. Transarc AFS 3.5 (patch2) client test –RH 5.2, kernel 2.2.10 SMP: OK –RH 5.2, kernel 2.2.10 SMP with NFSv3: NG with a CVS error –RH 6.0, kernel 2.2.10 SMP: OK –RH 6.0 kernel, 2.2.10 SMP with NFSv3: NG with a CVS error

5. Oct. 6, 1999PHENIX Comp. Mtg.5 PBS http://pbs.mrj.com Very flexible scheduling policies Very flexible queue setting Quick communication with the developing group ‘Interactive’ batch job available Current queues: see table –1 job / cpu –Negative priority leads leads to jobs more than 1 job/cpu. Pbs_server Pbs_momPbs_sched On ccjsun On each node priority# of jobs allowed hi215 pp215 gen20 short30

6. Oct. 6, 1999PHENIX Comp. Mtg.6 Prospects Installation of new hardware –SUN E450 server with four 400MHz CPUs and 1GB memory by the end of October Dedicated as a file server Login by general users will be prohibited. –1.6 TB disk by the end of October Served as working space for users Will have two 800GB partitions. –Alta Cluster boxes by the end of October 16 nodes = 32 CPUs with RH5.2 Pentium III 600MHz => 24 SPECint95/cpu Total of 1360 SPECint95 will be available by the end of October.

7. Oct. 6, 1999PHENIX Comp. Mtg.7 Schedule Hardware installation/tuning:- Nov 5 Stress test (MDCJ3?):Nov 8 – Dec 10 Hardware move:Dec 13 – Jan 14 Final test/tuning:Jan 17 – Jan 31? We are going to have a test period (MDCJ3?) in November and December for about one month. If the schedule of RCF/PHENIX MDC3(?) meets ours, CC-J may generate a part of simulation data for it.
