The sound of the virtual room conference proved to be so bad that it was necessary to switch to a telephone conference.
1. Paper modelling: New results, based on new information concerning detector layout, ROB mapping, event sizes, trigger menus, execution times, have to be produced. A problem is that this input to the model is not complete. The original date for the availability of the results is 1 March, but earlier availability is desirable. Concerning the presentation of the results J.Vermeulen has proposed in a meeting of the "brainstorming" group to present results for the high pT and B-physics triggers separately at the nominal LVL1 rate and no longer to present results for a 80 or 75 kHz LVL1 rate. The motivation for this is that the high LVL1 rates are about twice the nominal LVL1 rates, so that results for high LVL1 rate can be obtained by multiplying the corresponding results for the nominal LVL1 rate by a factor of 2. As the results for the B-physics trigger are to be presented separately the effect of scaling or not scaling its rate can immediately be judged from the results.
2. ROS modelling: Models based on the UML description have been implemented and are being debugged, it is intended to present results in the ROS workshop (first week of February).
3. Data Collection modelling and 4. HLT modelling: First UML diagrams have been produced, see also the email message from 14 January from K. Korcyl. The "strawman architecture" model is not yet running, work is going on with respect to the Ethernet models. The TCP model has been checked in into the at2sim repository. S. Wheeler is looking into modelling of the DFM and SFI and hopes to produce on a short time scale a draft document with UML diagrams. One subject to be addressed is traffic shaping.Ê
5. Ptolemy:Ê R. Cranfield reported that Ptolemy II does not seem to be a replacement for the previous version used for at2sim.
6. Simdaq: J.Vermeulen had no news other than that the program is now also running under MacOSX (the GUI has been "Carbonized").
7. "Chiba City": Although no longer an offical agenda item, R. Blair reported that the maximum number of outstanding events seemed to be responsible for the problems experienced. An attempt will be made to run the new data collection software on the system.
8. Workplan and status in relation to workplan: An updated task list is available .
9. Next meeting: The next meeting is planned for Wednesday 13 February, 16.00 h CERN time, via ISDN again,
