Paul Scherrer Institut 5232 Villigen PSI CHEP 2006 in Mumbay / / Matthias Schneebeli Generating Frameworks

Paul Scherrer Institut 5232 Villigen PSI CHEP 2006 in Mumbay / / Matthias Schneebeli Writing an Analysis Software Different approaches for writing an analysis software for an experiment Writing an analysis software specifically for the experiment Writing an analysis software for all HEP experiments - Generating an analysis framework - Adding experiment specific analysis code by hand  Limited use, only usable for 1 experiment  No help from other experiments  Impossible  Presented in this talk

Paul Scherrer Institut 5232 Villigen PSI CHEP 2006 in Mumbay / / Matthias Schneebeli Framework Composition of an Analysis Software Experiment independent part of the Framework Analysis Code Code is part of the distribution Code generated by a translation program Code implemented by the experimenter  Experiment dependent code which can be summarized in a experiment description Data structure Task structure Database access, DAQ access  Experiment dependent code which can not be summarized Physical Calculations Event Loop Support functions

Paul Scherrer Institut 5232 Villigen PSI CHEP 2006 in Mumbay / / Matthias Schneebeli Benefits of a generated Framework Saves Manpower Leads to better analysis frameworks Leads to better analysis software Clear separation between Framework and Analysis Code Consistent Program Structure -> Easy to read Less Handwritten Code Improvements are shared to other experiments

Paul Scherrer Institut 5232 Villigen PSI CHEP 2006 in Mumbay / / Matthias Schneebeli Conclusion  It’s possible to generate analysis frameworks  Generating frameworks has a lot of benefits  ROME is such a framework generator   Currently used at PSI (Switzerland) Los Alamos National Laboratory (USA) Triumf (Canada)  Try it out

Paul Scherrer Institut 5232 Villigen PSI CHEP 2006 in Mumbay / / Matthias Schneebeli Modularity ROME is based on Tasks and Folders. Tasks are independent calculation modules. The interface to the tasks are folders. Tasks can be combined or exchanged arbitrarily, as long as the interface matches. E.g. one can execute different calibration tasks without re-linking.
