HLT Farm
— Sector1 —
— Sector2 —
6 July 2006 DAQ, ECS for TPC commissioning 3
Changing from one sector to another
• Equipment Ids must be changed– Equipment Ids == data origin (i.e. from which sector)– Table of equipment Ids agreed (TPC, Offline, DAQ, HLT)
6 July 2006 DAQ, ECS for TPC commissioning 4
Working with HLT mode A+
• A+ – Data sent to HLT farm (splitters on and ‘forced’)– DAQ does not receive data from HLT (no HLT LDCs)
6 July 2006 DAQ, ECS for TPC commissioning 5
LTU-proxy
• A component of the ECS/TRIGGER interface– A process running on the VME crate where the TPC trigger
partition (LTU, TTCvi, TTCex) is located (lnxpool13)
• Is configurable– Two run modes (BC and pulser/edge)– In BC mode allows the selection of the event frequency– SOD and EOD events can be enabled/disabled
• Not a debugging tool– Does not offer all the feature of the ‘vmecrate ltu’ interactive
program (A.Jusko)
• Gives to the ECS the control of the LTU– Connected to the DAQ network (ethernet over fiber)
• Under the ECS control, it allows the generation of sequences of events starting with a SOD event and ending with an EOD event
6 July 2006 DAQ, ECS for TPC commissioning 6
HLT-proxy
• A component of the ECS/HLT interface
• Will run on the HLT farm
• For the time being we can use for test purposes a dummy version or (better) the HLT-proxy with TaskManager emulation provided by S.Bablok
• The HLT-proxy with TaskManager emulation runs on the same machine as the Detector Control Agent
6 July 2006 DAQ, ECS for TPC commissioning 7
ECS: TPC Detector Control Agent
• Controls standalone runs – Starts / stops DAQ and Trigger (LTU)– Dummy DCS for the time being
• Detector always ready– Dummy HLT-proxy or HLT-pxoxy with taskManager
emulator provided by S.Bablok• Receive the right sequence of commands
• It is a good starting point for the required development
6 July 2006 DAQ, ECS for TPC commissioning 11
To do
• DAQ:– Installation of DATE V5.19 (Monday 10 July 2006)
• Main difference TDSM (migration of files to CASTOR)• Probably the last version supported on SLC3
• ECS:– Interaction with a real DCS– Interaction with a real HLT-proxy– Implementation of various types of runs
• Pedestal runs (in progress)– Implemented in ECS– Roland preparing the required scripts– To be tested this week
• Datapath Test runs• Calibration Pulser runs• Physics runs
– Require a close collaboration with Luciano, Uli, Roland, ….
