1. DAQ Status Graham

2. EMU / EB status EMU framework prototype is complete. Prototype read, process and send modules are complete. XML configuration mechanism is complete. Testing underway.

3. Event Management Unit Reads data from multiple sources. Processes data Sends data to multiple destinations. Configured via XML. Controlled via Run Control. Reads data from multiple sources. Processes data Sends data to multiple destinations. Configured via XML. Controlled via Run Control.

5. EMU to EMU EMU to EMU over network, bit-bucket on same machine as second emu.

6. Single EMU to EMU Slope is 27 M word/s = 109 M byte/s, offset 190 μs Note: linear plot, rate independent of block size. Slope is 27 M word/s = 109 M byte/s, offset 190 μs Note: linear plot, rate independent of block size.

7. Six ROCs to 2x2 EB matrix to bit-bucket

8. Results Each bit-bucket reports 240 records/s at input. Each ROC reports 480 records/s at output. Since there are two bit-buckets this is exactly what you would hope. Independent of block size the block size x rate equals bandwidth of gigabit link. Network loads on all links are equal (measure packets/s).

9. Nine ROCs to 3x2 matrix to bit-bucket

10. 3x2 results Record rate same as 2x2 test, no impact from having slightly more complex system. As expected 50% of records go to each of the two bit- buckets. Network bandwidth tests show limiting factor is bandwidth of link into column B, the event building EMUs.

11. Next Have activated more nodes in DA Farm. Will test out larger arrays of EMUs. Will make processing in each EMU closer to that done in final EM. CPU does not seem to be a limiting factor. More than one interface per farm node?

12. CODA version 3 Recognized that DAQ group staffing should be 7 not 5. No funding. Identify projects to clarify priority. Get foot in door for when there is funding.
