System development/improvement

J-PARC

60MeV LINAC was commissioned with EPICS based control system.

Setting up EPICS 3.14 envrionment.

Channe Archiver performance test

IOC network performance evaluation.

Force Pcore6750 had shown poor network perforamance. -->New BSP solved this problem.

Stable opeartion under Fast Ethenet

Stil show poor performance for file transfer.

Preliminary test in KEKB control system shows that Force Pcore695 has reasonalbe network performance.

11MByte/sec with GbE to copy file from NFS server

System development/improvement

KEKB/PF-AR

Improvement fro KEKBLogger system.

Data chache on users directory

Distributed retrieve engine.

Share files over NFS

Each hosts run data retreival progam

Data retreival program (kblogrd) runs both big- -and little- endian machines.
