CC-J Status

• Number of Users Accounts– CC-J Adimin … 7

– PHENIX-J … 28 (regional use)

– PWG MC … 2• CPU usage (right figure)• but, no CPU factor applied, ...

• Regional use– DST production

• trial version: phs5+TOF projection

– post DST analysis

• MC production– (2+1) x 100 K events ONLY PISA processed

• Problems due to PRDF writing• Response and MC reconstruction chain maintenance required!

CC-J Status II

• 100 K MC– So far only PISA code works– Run00a and run00b finished– Second round of run00b under process

• With new MVD geometry

– A couple of troubles• Root library changed during production• Root has 2x109 bytes limit

– Split to 1000 events/run (run00b)

• Objectivity/DB– Dead copy of 10/2, 10/26 version worked at CC-J– New proposal: NFS version, World wide Time stamp

Nov. 8, 2000 RIKEN CC-J

New Hardware

• Same as S.Yokkaichi reported last September• New Fiber channel RAID:

– 2.85TB soon, another one later

• New Alta Cluster and upgrade– Dual 1 GHz CPU x 16 nodes, soon. Another 16 nodes l

ater.

– Slower 450MHz (32 CPU) and smaller Disks will be replaced (933MHz, 18 GB SCSI)

– ECC memory

• Sun E450 for another NFS server (or Data mining)
