The 1 Teraflops QCDSP computer
The QCDSP computer (Quantum Chromodynamics on Digital Signal Processors) is an inexpensive, massively parallel computer intended primarily for simulations in lattice gauge theory. Currently, two large QCDSP machines are in full-time use: an 8,192 processor, 0.4 Teraflops machine at Columbia University and an 12,288 processor, 0.6 Teraflops machine at the RIKEN-BNL Research Center at Brookhaven ...
متن کاملStatus of the QCDSP project
We describe the completed 8,192-node, 0.4Tflops machine at Columbia as well as the 12,288-node, 0.6Tflops machine assembled at the RIKEN Brookhaven Research Center. Present performance as well as our experience in commissioning these large machines is presented. We outline our on-going physics program and explain how the configuration of the machine is varied to support a wide range of lattice ...
متن کاملQCDOC: A lo-teraflops scale computer for lattice QCD *
The architecture of a new claw of computem, optimised for lattice QCD calculations, is described. An individual node is based on a single integrated circuit containing a PowerPC 3> bit integer processor with a 1 Gflops 64-bit IEEE floating point unit, 4 Mbyte of memory, 8 Gbit/eec nearest-neighbor communications end additional control and diagnostic circuitry. The machine’s name, QCDOC, derives...

متن کاملBuilding the Teraflops/Petabytes Production Supercomputing Center
In just one decade, the 1990s, supercomputer centers have undergone two fundamental transitions which require rethinking their operation and their role in high performance computing. The first transition in the early to mid-1990s resulted from a technology change in high performance computing architecture. Highly parallel distributed memory machines built from commodity parts increased the oper...
