apeNEXT: A multi-TFlops Computer for Simulations in Lattice Gauge Theory

We present the APE (Array Processor Experiment) project for the development of dedicated parallel computers for numerical simulations in lattice gauge theories. While APEmille is a production machine in today's physics simulations at various sites in Europe, a new machine, apeNEXT, is currently being developed to provide multi-Tflops computing performance. Like previous APE machines, the new supercomputer is largely custom designed and specifically optimized for simulations of Lattice QCD.Comment: Poster at the XXIII Physics in Collisions Conference (PIC03), Zeuthen, Germany, June 2003, 3 pages, Latex.

The apeNEXT project (Status report)

We present the current status of the apeNEXT project. Aim of this project is the development of the next generation of APE machines which will provide multi-teraflop computing power. Like previous machines, apeNEXT is based on a custom designed processor, which is specifically optimized for simulating QCD. We discuss the machine design, report on benchmarks, and give an overview on the status of the software development.Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 8 pages, LaTeX, 12 eps figures.

apeNEXT: A Multi-Tflops LQCD Computing Project

This paper is a slightly modified and reduced version of the proposal of the {\bf apeNEXT} project, which was submitted to DESY and INFN in spring 2000. .It presents the basic motivations and ideas of a next generation lattice QCD (LQCD) computing project, whose goal is the construction and operation of several large scale Multi-TFlops LQCD engines, providing an integrated peak performance of tens of TFlops, and a sustained (double precision) performance on key LQCD kernels of about 50% of peak speed

Computing for LQCD: apeNEXT

The apeNEXT system is the latest in the APE collaboration's series of parallel computers for computationally intensive calculations such as quantum chromodynamics on the lattice. The authors describe the computer architectural choices that have been shaped by almost two decades of collaboration activity

The apeNEXT project

In this talk we report on the status of the apeNEXT project. apeNEXT is the last of a family of parallel computers designed, in a research environment, to provide multi-teraflops computing power to scientists involved in heavy numerical simulations. The architecture and the custom chip are optimized for Lattice QCD (LQCD) calculations but the favourable price performance ratio and the good efficiency for other kind of calculations make it a quite interesting tool for a large class of scientific problems

apeNEXT: a multi-TFlops computer for elementary particle physics

We present the apeNEXT project which is currently developing a massively parallel computer with a multi-TFlops performance. Like previous APE machines. the new supercomputer is completely custom designed and is specifically optimized for simulating the theory of strong interactions, quantum chromodynamics (QCD). We assess the performance for key application kernels and make a comparison with other machines used for these kind of simulations. Finally, we give an outlook on future developments
