Open simulation tasks or tasks with simulation involvement

Implementation of alternative formats for MC data

Lead (tools, or other) group Software/Computing
Other relevant groups (if any) Simulation, All physics WGs interested in large statistics MC simulations
Task name Implementation of alternative formats for MC data
Task description Currently the full DST is written for MC events (~400kB/event). It should be possible to achieve a factor 10 reduction by removing not needed information (e.g. HepMC event) and adopting tricks used for the real data microDST to save only relevant MC truth info. Since the relevant info may be analysis dependent, rather than a single format one should provide tools that allow to customise the format for each production.
Estimated total effort required (FTE) ~ 1 FTE for a few months for programming, plus dedicated contacts in each WG to provide requirements and feedback
Deadline ASAP
People/groups currently involved B2OC WG, Chris Jones, Gloria Corti, Marco Cattaneo
New effort required? Yes, particularly for testing the various options
Other comments This could be an extremely useful tool for simulation, where usable statistics are currently limited by storage.
