Collaboration Meeting

    We discussed the agenda for the offline session at the up-coming
    collaboration meeting. A tentative agenda:
      * Overview: Mark
      * CCDB: Dmitry
      * Tracking: Simon
      * TBD: David

Data Challenge Status

    Curtis has started writing a [28]report on the recently completed data
    challenge. There are still a lot of sections to be filled in.

CCDB Status

    Dmitry gave a report:
      * The DANA library of sim-recon now requires CCDB to build. CCDB is
        still optional however.
      * David has updated HDGeant and mcsmear use the new DANA (the
        DApplication class in particular).
      * The code has been tested on MacOs
      * It has also been tested with the clang compiler.
      * The next release, ccdb-0.07, is in preparation.
           + It will include the use of Resources to handle large files
             like the magnetic field.
      * There is still a problem on CentOS 5 that Mark and Dmitry are
        chasing down.

New CPU architecture from Intel

    David gave us an introduction to a new technology from Intel, the Xeon
    Phi MIC. This is Intel's answer to the recent popularity of GPU's for
    large-scale computations. See [29]his talk for details. The outline:
      * Terminology
      * Some System Details
      * Performance using JANA TestSpeed Plugin
      * Results
      * Summary

    Study of the board is just starting.

JANA Resources update

    David gave us and update on the work he presented [30]last November.
    See [31]his slides for details. He has incorporated features that we
    discussed at the initial presentation.
