7 summary and future prospective

7. Summary and future prospective

  • Summary

  • Lattice QCD:non-perturbative definition of QCD

    • ab initio calculations of hadronic properties

  • numerical methods intensively applied

    • => proof of QCD, determination of fundamental parameters

    • => prediction of QCD: HME's, QGP, ...

    • <=> matrix models, quantum gravity, NC, ...

      • <= theoretical developments

        • (improvement, chiral fermions, ...)

    • <= technical developments

      • (algorithms, vectorization, parallelization, ...)

  • <= progress in computer technologies

    • (super/parallel computers, clusters, grid, ...)

  • All three are important and have equally contributed!


  • 7 future dedicated computers

    7. Future: dedicated computers

    As the most intensive power user, LQCD have been crucially

    contributed the development of vector and parallel computers.

    Computers dedicated for LQCD

    • QCDOC 20TFLOPS

    • apeNEXT

      • PC clusters

    CP-PACS

    QCDSP

    APE-100

    QCDPAX

    Columbia

    APE

    APEmille


    7 future lqa and ildg

    7. Future: LQA and ILDG

    • Lattice QCD Archive

      • http://www.lqa.rccp.tsukuba.ac.jp/

    • Grid-based Archive for LQCD.

    • CP-PACS Nf=2 configurations.

    • Will open around end of Dec. 2003.

    • This Archive is a part of

    Search engine by M. Sato @ CCP, Tsukuba

    • International Lattice Data Grid

      • http://www.lqcd.org/ildg/tiki-index.php

    • Intern'l initiative to create a Data Grid for LQCD.

    • Current members: UK, USA, Japan, Germany

    • Now working on middleware and metadata formats => step by step 2004–
