Forty some people from various groups gathered in the control room and the room next to it and attempted to take a run, using the primary data path. We had about 8 stations available in the control room for the workshop.
|Dan is studying at the Level 1 Framework screen in the room next to the control room. There were 8 pc's available in this room for various groups of people.|
|Due to some unresolved issues in MFC boards and the lack of Level 2 accept transfer, we could not use muon crates for this workshop. Instead we used two calorimeter crates (4a and 4b) in the rack M310. Luckly Dave Cutts brought another Run II VBD card so that we could take a single detector multi-crate run.|
|These two large machines which look like ventilation towers are two of the three online host machines. These are DEC unix machines which holds various online applications, databases, controls informations, etc.|
|Online host GIGA bit switch racks on the 2nd floor of DAB. We shipped the data over to the SAM system on the 2nd floor Feynmann Computing Center and logged them onto tapes in the robot to be used in RunII data taking.|
|The L3/DAQ guys, from left to right Sean, Dave, and Genna, are computing the expected data size. We expected fixed 37kB of events but the size were varying in event-by-event basis. This was due to some compression applied in the L3 event assembly. Gordon Watts' L3 Super did not participated in the workshop due to some minor bugs.|
|At around 10:10am, Michael Begel started the first run with all available components participating in the run. Level 1 framework was configured by the COOR, level 3 components assembles the data, combining both the cal crates in one events, online/DAQ applications functioned as expected, and two calorimeter examines were getting the events, making histograms. The event display ran sort of an offline mode, producing the displays.|
|Overall the integration workshop was an extremely successful one. The process went very smoothly. We found lots of issues and solved on the spot to the level we could take data, could monitor them, and could even make event displays out of them. This exercise demonstrates that our primary DAQ path and single detector multi-crate unpacking works. We just need to see the real cosmic ray, using muon system.|
