2 Introduction The LCG build system Tools and core elements Test, nightly and release infrastructures Scheduler and Dashboard Summary and future plans 28/09/15Quality and Testing PH-SFT infrastructure 2 OUTLOOK

3 Development and maintenance of common scientific software for the experiments in collaboration with the PH and IT departments and external HEP institutes Areas covered by the group: Simulation: Geant4, GeantV Frameworks: ROOT Distributed systems: CERN VM, CERNVMFS 28/09/15Quality and Testing PH-SFT infrastructure 3 PH-SFT GROUP

4  Goals of the project:  Provision of consistent releases of external and LCG application PKGs to both experimental and theoretical communities  Provide daily tests and previews of incoming releases to users 28/09/15Quality and Testing PH-SFT infrastructure 4 THE PH-SFT PACKAGES AND RELEASES PROJECT WITHIN THE LHC SOFTWARE STACK Event Experiments specific Packages External packages non-HEP specific Detector Calib Simul.
