“Physics Lists”

First Working Group Meeting


Mandate
Mandate

  • Communicate with physics working groups to maintain the physics lists etc and their parameter settings updated to current

  • Communicate with kernel working groups to make sure physics lists etc should be compatible with multithreading and other new features

  • Maintain the documentation, user guide, etc.

  • Communicate with example working groups to promote the proper use of updated physics lists etc.

  • Conduct physics performance monitoring and notice issues to relevant (physics) developers

  • Develop and maintain common tools for physics validation

  • Maintain the public web page of physics validation

  • Source: Proposal of creating Physics List Working Group


Working group name
Working group name

  • We may choose our name, original proposal ‘Physics List’ reflects not all activities

  • Mandate also includes

    • Physics performance monitoring

    • Validation tools

  • Proposals?

    • Physics Lists and Validation Tools

    • Physics Lists and Tools


Regular meetings frequency
Regular Meetings frequency

  • Frequency

    • bi-monthly

    • regular

      • Which day, when in month


Plan of work
Plan of Work

  • See draft at http://edupad.ch/QmnikkyVKD

    • Finalize plan

    • Schedule work items per release or quaterly

  • Remarks:

    • How do we track progress

      • Geant4 Jira?

    • Consolidate code, less new or repetiton

      • E.g. two physics lists factories, no need for yaplf

      • Modular builds of G4

    • Documentation and web: user centric


Prioritize work items
Prioritize Work Items

  • Development

    • Documentation, create & improve

      • User documents: create doc

      • Web pages, complete, consolidate, ….

    • Public web page for physics validation

      • Review web

      • Enhance tool used

    • References (histograms) for physics verification and regression testing

  • Ongoing activities

    • Physics performance monitoring


Web p ages
Web Pages

  • Merge existing pages at Geant4 – Twiki

    • Linked from geant4->Validation

  • Validation(twiki)

  • Physics lists (link)

    • Including processes and cross sections catalogs

  • Into new page

    • Using this twiki?


  • Reference histograms
    Reference histograms

    • Wish to compare results to reference results

    • Reference results will change with time

      • Developer decides on new set of reference data

      • Keep references for some time, maybe variable

        • References of releases will be kept for years

    • Reference data may be binary, like root files

      • Svn (@cern) explicitely forbids binary (root) files.

    • Use indirection, svn only keeps ‘link’ to binary data accessible e.g. via URL
