Author

Bodin, F., Boucaud, Ph., Cabibbo, N., Di Carlo, F., De Pietri, R., Di Renzo, F., Kaldass, H., Lonardo, A., Lukyanov, M., De Luca, S., Micheli, J., Morenas, V., Pene, O., Pleiter, D., Paschedag, N., Rapuano, F., Rossetti, D., Sartori, L., Schifano, F., Simma, H., Tripiccione, R., and Vicini, P.

Abstract

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.

This talk is divided in two parts. In the first part, we will summarize the status of the APEmille project that will be completed by the end of the year. We will then devote the rest of the talk to the description of a new project for a multi-TeraFlop machine, apeNEXT.

Abstract

In this talk I 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 axe 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

Abstract

APE is a family of supercomputers architecturally optimized for the numerical simulation of quantum field theories. Current generation APE systems (APEmille) have been commissioned at several European sites. When all planned systems are installed, later this year, a total peak processing power of about 2 TFlops will be available. A new generation system, apeNEXT, is under development. It adds several new features to the established APE architecture. Performance will be boosted towards the 10 Tflops range. (C) 2002 Published by Elsevier Science B.V.

Abstract

Publisher Summary This chapter discusses the apeNEXl 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). The performance for key application kernels is assessed and a comparison is made with other machines used for these kinds of simulations. A functional model of the machine design has been used for benchmarking the architecture. The chapter presents a detailed discussion of the results and showed that the actual design goals of the project have been reached. Benchmark programs indicate that it will be possible to run key lattice gauge theory kernels at a sustained performance of 50% or more. While apeNEXT is designed as a special purpose machine optimized for simulating QCD. To make efficient use of these vast resources and to push towards development of future high performance computing capabilities an initiative on scientific parallel computing (SciParC) has been launched.

Abstract

APE is a family of supercomputers architecturally optimized for the numerical simulation of quantum field theories. Current generation APE systems (APEmille) have been commissioned at several European sites. When all planned systems are installed, later this year, a total peak processing power of about 2 TFlops will be available. A new generation system, apeNEXT, is under development. It adds several new features to the established APE architecture. Performance will be boosted towards the 10 Tflops range. (C) 2002 Published by Elsevier Science B.V.

Abstract

This paper presents the status of the APEmille project, which is essentially completed, as far as machine development and construction is concerned. Several large installations of APEmille are in use for physics production runs leading to many new results presented at this conference. This paper briefly summarizes the APEmille architecture, reviews the status of the installations and presents some performance figures for physics codes., Lattice2001(algorithms), 3 pages, 1 eps figure
