ATLAS Offline Computing Review

Review of ATLAS Computing: Scope and Agenda  html (15kB), pdf (35kB) or doc (48kB)
The objective of this review is to assess the status of the strategic planning and progress of ATLAS computing and to
recommend actions that will help achieve the collaboration’s goals in this important area.

Supporting Documents

The ATLAS Offline Computing is documented on the web here.
In order to facilitate the task of the review committee, in the following a few key links from the web have been collected. This page will grow as need arises.
  • ATLAS Computing a presentation at CHEP97, Berlin
  • The Computing Technical Proposal or (ps) includes a description of how the ATLAS software will evolve from its current state to a more modern Object Oriented system.
  • Introduction to Atlas softwareThis document does not address the new software maintained under cvs with srt.

    • Computing planning and project management

    Basics and major milestones are contained in the Computing technical proposal. Recently more detailed milestones have been presented at the ATLAS plenary (Slides of J. Knobloch are here).

    ATLAS Database Strategy

    The ATLAS Database Strategy is sketched in the Computing Technical Proposal. Latest developments have been presented by RD Schaffer at CHEP and at a recent ATLAS plenary.
    Please find here the Slides from CHEP98 and the Slides from Plenary as well as the writeup of the CHEP presentation as pdf  (49kB).

    ATLAS Software Process 
    Title  What  Formats  Who 
    Introduction to the Atlas Software Process This is intended to be quite light reading html and ps R. Candlin
    User's Guide to Software Development for ATLAS This is the first version of an introduction for new people to the intricacies of the ATLAS software. It summarises parts of the CTP and of the ASP and explains how to get started. various R. Candlin
    The Atlas Software Process The definitive document, which is still undergoing revisions. Sections on testing and on evaluating external software have recently been added. various S.M.Fisher (as contact person)
    Rules for requirements documents This describes what a requirements document should contain. various S.M.Fisher
    OO design standards for ATLAS These are the standards to be followed when doing OO design for C++. various R.Candlin and S.M.Fisher
    C++ Coding Standards for ATLAS These are the standards to be followed when writing C++. various S.M.Fisher and L.A.Tuura
    Questionnaire on External Software This is a questionnaire referred which is to be completed as part of the proecedurte for accepting a piece of external software. various J.Hrivnac

    Software release and documentation tools

    The ATLAS offline software is maintained in a cvs repository using software release tools SRT.
    An introduction to SRT can be found at L. Tuura's presentation at CHEP98.
    The software is documented using the LIGHT system. The software documentation based on LIGHT is available here.

    Common tools shared with other experiments

    We develop tools together with other experiments, institutes and the CERN computing division tools that represent esential ingredients to our computing strategy:
    GEANT 4 - simulation toolset
    RD45 - Object-oriented database for event storage
    LHC++ - successor of the CERN library for OO developments
    MONARC - simulation and study of regional centres
