Analysis framework for GLORIA

Presentation duration: 30 minutes

Presenter: Aleksander Filip Zarnecki

Luiza analysis framework for GLORIA was based on the Marlin package developed the new High Energy Physics (HEP) project, International Linear Collider (ILC), data analysis. HEP experiments have to deal with enormous ammounts of data and distributed data analysis is a must, so the Marlin framework concept seemed to be well suited for GLORIA needs. The idea (and large parts of code) taken from Marlin is that every computing task is implemented as a processor (module) that analyzes the data stored in an internal data structure and created additional output is also added to that collection. The advantage of such a modular approach is to keep things as simple as possible. Every single step of the full analysis chain that goes eg. from raw images to light curves can be processed step by step and the output of each step is still self consistent and can be fed in to the next step without any manipulation.
