  1. ODR development Progress in the following areas: • Data write to disk. • Tx message. • Interface to DOOCS and processing messages: a) setting up parameters, b) passing commands, c) passing messages to LDA, d) passing messages back to DOOCS

  2. Performance (continuation)‏ Improvements in performance when accessing more then one channel. The maximum performance achieved for 3-channels access. Adding additional Channel (4-channel access) does not yield improvement in transfer rate.

  3. Performance (data to disk)‏ Single channel. Data written to RAID array. Maximum bandwidth for the array: 300 MB/s. Adding active channel has no effect on the rate (remain constant). Best performance for scatter-gather scenario.

  4. Future development/work in progress • Test code stability. • Create event fragment data base (inside DOOCS ?)‏ • Test connectivity to LDA with the “real” LDA hardware • Improve/investigate data write to the disk (contiguous data buffer, stability of the rate, etc.).
