Meeting on a Common Analysis Framework between ATLAS and CMS (30 March 2012)
Attendees
- CERN: Maria Girone, Paul Nilsson, Fernando Barreiro Megino, Simone Campana, Domenico Giordano, Alexei Klimentov, Maarten Litmaath, Stephen Gowdy, Daniel van der Ster, Nicolo Magini, Mattia Cinquilli, Daniele Spiga, Tadashi Maeno, Alessandro di Girolamo
- Remote: Rodney Walker, Torre Wenaus, Hans von der Schmitt, Daniele Bonacorsi, Kaushik De
Daniele S. presented the status of the investigation on the feasibility of having a common analysis framework between ATLAS and CMS. The slides are uploaded to the agenda page. There is a google document where the progress is tracked: https://docs.google.com/document/d/1PJDBuH4gd5w5CzUJ5n2i7uOaFrhcYo5-5YErQdpzjvo/edit.
Currently the basic workflows of both experiments have been analyzed and building blocks have been identified. For a more detailed view of some components the experts will be contacted and discussions will be held in the beginning of next week.
Comments on the presentation:
- Daniele B. pointed out that we have to include in the study the possibility for users of troubleshooting, clean-up and resuming jobs from the point where they failed etc.
- Maarten asked about the GlideInWMS effort in ATLAS. This is being investigated by Rod and is currently under testing phase. There are concerns about the way that the connections are kept between elements and the possibility of loosing jobs in case the connection breaks. Maarten offered his help and will be kept in the loop in the emails to Igor in order to speed up the process.
- Simone asked to add the access to input files to the table and evaluate the differences between CMS and ATLAS.
- Alexei asked for a report or status update at the TIM
- There was confusion about the bullet "Data Management & Workload Management coupling" in slide 9. It was clarified that - at least in the scope of this evaluation - there is no intention of creating a common Data Mangement system. The bullet just refers to the fact that the interactions between the WM and DM systems have to be studied and make sure that there are no show-stoppers in a possible common approach.
- Daniele B. recommended that tasks are prioritized, so that the feasibility study investigates urgent tasks before CHEP and less important tasks could hypothetically left for after the deadline.
- Next meeting will be on Thursday April 5 at 14:00
