Partitioning

Partitioning. Assumptions: Subdetectors are the natural units for partitions The smallest sensible unit for a partition is a TTC zone (~40) A subdetector is hierarchically organized in a tree-like structure DCS can act on each branch and leave of this tree (down to individual channels).

  1. Partitioning Assumptions: • Subdetectors are the natural units for partitions • The smallest sensible unit for a partition is a TTC zone (~40) • A subdetector is hierarchically organized in a tree-like structure • DCS can act on each branch and leave of this tree (down to individual channels) TDAQ WS: Global Issues, 24/4/2002, H.J.Burckhart

  2. Partitioning Questions (and suggestions): • Partitions have to be defined at one single place (suggest: DAQ) • From this place coherent booking of • (Part of ) subdetector(s) • read-out chain • environment conditions and services • Can partition units be statically defined, e.g. the 40 TTC zones? If yes: • DCS can arrange its state model accordingly • Should it be possible to dynamically (re-)define partitions? Suggest: yes. Example: • (part of) a subdetectors trips HV: • take this part out of the read out • recover • take it back into the read out TDAQ WS: Global Issues, 24/4/2002, H.J.Burckhart
