PAT - Physics Analysis Toolkit: Developer's area

Complete:

This page collects information on the so called "Layer 1" of the Physics Analysis Toolkit. This Layer-1 has evolved in the meantime into a Layer-0 and a Layer-1, both are covered here.

About the PAT group

The Physics Analysis Toolkit (PAT) effort is part of the Analysis Tools group. This is not a closed group, anyone willing to collaborate is very welcome - as the effort is big and the time is short; comments and criticisms are also welcome, but if someone writes that some functionality is "absolutely needed" he might be considered a volunteer to implement it

For further information on the Physics Analysis Toolkit and related task force, you can look at the meetings on indico http://indico.cern.ch/categoryDisplay.py?categId=1402 in particular in the minutes of the first meeting there is attached the full mandate of the task force.

Note that information on these pages, and especially in the minutes of the "chats" on PAT is not considered "official" or "to be released to the public", it's mostly meant for the use of those work on implementing this PAT.

Recipe for the impatient user

Recipes have been moved to SWGuidePATRecipes.

Developers corner

To-do list

• WORK : list of items we're working on, or on which work should start soon; feel free to add items, and to pick some of the "pending" ones to work on.

Location of the code

• DataFormats are in DataFormats/PatCandidates
• The code is in CMS.PhysicsTools under PatAlgos (EDProducers & such) and in PatUtils (standalone algorithms, should have no CMSSW dependency)
• Code which is not PAT specific should go in standard PhysicsTools packages and not in Pat ones

Algorithms, tools and modules

• Algorithms implemented
• Tools and Helpers non physics tools utilities and helpers (e.g. to work with Refs)
• Modules that you can use directly from cfg

Features awaiting to be ported

See SWGuidePatBackports for a list of items that might need to be backported to an older release, or ported forward from and old release to the HEAD.

Archive of information

Here is the information I could collect, please add whatever you will find missing. Note that these documents are often full of jargon which might not be too informative for people who misses the background from other talks

• Proposed list of algorithms for PAT layer 1 (HN thread started by Giovanni Petrucciani)
• Summary of discussion on PAT layer 1 + proposal Summary of many info from HN, meetings and chats among people involved in PAT; sent by private email to a large list of people that had expressed interest in layer 1, not on the HN as it's too much "draft". (see also the slides at PAT meeting, especially those by Colin where the "top projection" is introduced)
  • Follow up some discussion on "top projection", and possible interpretations of it in CMSSW
• Part 1 of minutes of the 11/01/08 chat on PAT layer 1: "what we think layer 1 should deliver"; sent by email to the same large group of people
• Part 1 of minutes of the 11/01/08 chat + proposed action items for PAT layer 1, not sent by email, it's just attached here.
