Detailed Description

Global Cellular Automaton-based HLT tracker for TPC detector The class reconstructs tracks in the whole TPC It calls the AliHLTTPCCATracker slice tracker and constructs the global TPC tracks by merging the slice tracks

The tracker is designed stand-alone. It will be integrated to the HLT framework via AliHLTTPCCAGBTrackerComponent interface, and to off-line framework via TPC/AliTPCtrackerCA class The class is under construction.

void AliHLTTPCCAGBTracker::FindTracks ( )

The necessary data is transfered to the track-finder

The necessary data is transfered to the track-finder Data is structured and saved by track-finders for each sector. To speed up the process in each row 2D-grid with the bin size inversely proportional to the number of hits in the row is introduced. Hits are sorted by grid bins and for each grid bin 1st hit is found and saved. Such data structure allows to quickly find closest hits to the point with given coordinates, which is required while neighbours hits are searched and additional hits are attached to segments.

USE_TIMERS

give the data to the slice tracker

USE_TIMERS

Read hits, row by row

Run the slice trackers in parallel. The mutex is only necessary for storing the timings after the reconstruction.
