Concluding Remarks

The MILC Collaboration is currently doing most of its computations on computers that have a cluster architecture. Some use commodity parts and others do not.

  • Vendor designed supercomputers
      Compaq: Terascale Computer System (PSC)

      IBM: Blue Horizon (SCSC), Seaborg (NERSC), Florida State, Indiana, Utah
       

  • Commodity Clusters
      PC/Ethernet: Colorado, Florida State, Indiana, Utah  

      PC/Myrinet: RoadRunner, Los Lobos (AHPCC); Platium (NCSA); QCD80 (FNAL); NERSC



The DOE SciDAC program will be funding software development and cluster building for lattice QCD in the next three years.

An Itanium cluster called Titan in nearing deployment at NCSA. The DTF will have two multiTeraflop clusters at NCSA and SDSC.

With exciting developments in processors (Pentium IV, Itanium, Alpha EV68) and networking (Infiniband, 10 GigE, Quadrics, Scali), there should be good opportunity to improve the cost-effectiveness and scalability of clusters for LQCD calculations.
