Framework redesign

Framework Redesign

  • Hierarchy of devices

  • Configuration of devices

  • Integration of a new device type


Hierarchy of devices

Hierarchy of devices

  • Hardware View

    • Devices organized in families

    • Dp names follows tree structure

    • Default name proposed at any level, but user can change it


Hardware view

Hardware View


Hierarchy of devices1

Hierarchy of devices

  • Logical View

    • Dp alias follows tree structure

    • Can contain:

      • Detector logical structure (subdetectors, subsystems, etc)

      • Independent Control Units made grouping devices, that will be moved afterwards.

Open issues

Open issues

  • How many views are needed?

  • Relation with the Control Hierarchy.

  • How are the children of a device specified?

    • Dpes inside every device

    • Querying with dpNames

  • Distributed systems

    • How does the hierarchy “cross the border” to another system?


Performance of query

Performance of query

  • PIV 1,8 GHz, 512 Mbytes

  • dpNames + patternMatch to find children

  • 1400 datapoints (5 crates, 16 boards/crate, 16 channels/board)

    • Children of CAEN: ~40-45 ms

    • Children of CAEN/crate001: ~10 ms

    • Children of CAEN/crate001/board01: ~1 ms

  • 14000 datapoints (50 crates)
