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.
