ATLAS+CMS discussion of “Computers in the search for the Higgs Boson”for JCSS

Ian Fisk (FNAL) + Norman McCubbin (RAL)


Quick summary

Quick summary

  • ATLAS + CMS have been invited to producea “special issue” forthe Journal for Computer and System Science (JCSS) on “Computing in the search for the Higgs boson”.

  • This is supported at spokesperson level and has been discussed since ~start of year within the experiments, and jointly (mainly Ian and Norman).

  • We are agreed that:

    • Although ‘Higgs’ is in title, this special issue is about computing+software (C+S) in general, and is not restricted to Higgs;

    • It is roughly analogous to the big papers (written separately by ATLAS and CMS) describing the detectors ‘as built’;

    • ‘Performance plots’ will be used by way of illustration, but this is NOT the comprehensive “Run 1 Performance” paper(s).

    • Noting the JCSS readership, we aim for sections/chapters to be ‘joint ATLAS/CMS’ where that is sensible and feasible. (eg Introduction.)

Outline

Outline

  • The most recent version (1st April) of the outline has headings:

    • Introduction (physics; computing ‘challenge’)

    • Overview (from collisions to publication)

    • On-line

    • Off-line processing

    • Distributed data-processing (but this is not the WLCG paper!)

    • Distributed analysis

    • Computing Project Management and Tools

    • Outlook

  • Interspersed with possible “Technology Themes”:

    • Databases

    • Algorithmic code

    • Grid

    • Visualisation

    • Multi-threading

Aim of today s meeting

Aim of today’s meeting

  • Discuss:

    • General approach (in terms of content);

    • Discussion of draft outline, including technology themes;

    • Modus operandi (scribendi??)

    • Time table

  • We (Ian and Norman) would like to suggest a “write something fast” approach:

    • Next week: capture outcome of this meeting, update outline, identify author groups of the various sections etc

    • Ask authorsto discuss among themselves, and come back with “~500 words per person” for a (half-day) meeting on July 16th (before Snowmass, EPS, vacations) to assess what works, what doesn’t, and adjust scope, contents etc accordingly.

    • Aim for first, very rough, assembly of text for early September.

    • (Delay will not make this easier to write .. )
