  8. Wendelstein 7-X TTE System OverviewJ.Schacht, IPP Greifswald CMS TTC System ImplementationJ.Troska, CERN Feedback and High Speed Synchronous Control • feedback-systems are the backbone of fusion experiments • less FPGA • domain of DSPs • high-speed synchronized control systems • accelerator controls • experiment controls • fusion experiments A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva

  9. see at ICALEPCS 2005: Embedded PCs for Electronics Control in LHCb(WE1.2-4O) Control, Monitoring, GUIs, and Online Databases • real-time systems need controls • “a condensed version of ICALEPCS” • tendencies • SCADA systems • larger frameworks • load-balancing • databases A see at ICALEPCS 2005: The JCOP Framework (WE2.1-6O) Tools for the Automation of Large Physics Experiments (FR1.4-5O) A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva

  10. 2-D Hough Histogram Simulation for CBMJ.Gläß, Mannheim Univ. Algorithm Implementation • almost all presentations in the other tracks contained ideas on algorithms and their implementation • this track focused on novel ideas • tendency to implement more complex algorithms in FPGAs A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva

  11. The ATLAS DetectorATLAS Collaboration, CERN RatCAPM.Purschke, BNL PAMELAF.Sebastiani, INFN Rome II Data Acquisition Systems • central real-time application in most experiments • full range • small • space and weight-constrained • highly complex architectures A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva

  12. BTev 3-level TriggerM.Wang, FNAL Trigger • this track mostly presented implementations of complex systems • typical idea:use of commodityhardware A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva

  13. Fast Networks and Event Building • use of fast networks in readout-systems and event building solves many problems of the past • most implementations shift from custom solutions or ATM to Gbit-Ethernet A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva

  14. Online Processing Farms and High Level Triggers • in the last generation of experiments, computing farms were only used offline • most experiments run higher level trigger algorithms on computing farms as part of the online system • some experiments investigate the possibility of using remote computing farms in real-time for trigger and data acquisition • online computing farms are a challenge for infrastructure in terms of cooling and cabling A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva

  15. Student Awards • Lana Abadie, LHCb:Representing Dataflow and Routing Tables using a Database • seen at ICALEPCS 2005MO4A.2-7O • Petter Hofverberg, KTH:The Data Acquisition System of the Stockholm Educational Air Shower Array A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva

  16. Conclusions and Outlook • two main directions in 2005 • placing more complex algorithms into hardware • FPGA • change of mind • less sophisticated real-time trigger • complete read-out at higher rates • Real Time 20xx • combine the trends? • complete read-out in hardware • low-level trigger • high-level trigger • DAQ A Summary of the IEEE Real Time 2005 Conference Sascha Marc Schmeling, CERN • ICALEPCS 2005, Geneva
