Running the full reconstruction Ron Cassell

Objective Make a list of ReconstructedParticles. Use full tracking with the UI pfa algorithm. Write out the lcio file: should have no null pointers.(All objects reachable starting with the ReconstructedParticles need to be output)

Problems There were many, both in details of the output and errors degrading performance. Due to a heroic effort from Mat, Tae Jeong and Rich all the identified problems have been solved. Some performance issues still remain, with no obvious quick solutions.

Tag it? Suggest we create a tagged version and start the reconstruction.

Details to make it happen For a small cost in disk space, we could add LumiCalHits, BeamCalHits and MCParticleEndPointEnergy collections to the output, preserving the full slic output in the recon files. Do we want to rename the ReconstructedParticle collection?(currently FlushedDTreeReclusteredParticles) What do we name the output file? (Currently inputfilename_UIT.slcio) Where do we put the output file? (Currently inputfiledir/../reco/UI/) Should we put the Driver in a try/catch loop, and if so what information should be logged about skipped events?

Resources: current estimate SM sample at 500GeV: /evt~21sec, ~180kb/evt. 500GeV: /evt~80sec, ~280kb/evt.
