Architecture of highly parallel ap1000 computer

Systems and Computers in Japan, 1993
AbstractThis paper describes the architectural features of the AP1000 message‐passing computer. The architecture is designed to speed up barrier synchronization, data distribution and collection, broadcasting, and message handling. In recent message‐passing computers, the most significant communication overhead is that associated with interrupt ...

Le réacteur AP1000

Annales des Mines - Réalités industrielles, 2012
L’année écoulée a été difficile pour l’industrie nucléaire, notamment pour les entreprises cherchant à construire de nouvelles centrales. Il est inutile de rappeler les événements survenus à Fukushima, au Japon, en mars 2011. Ceux-ci auront un impact sur l’ensemble des projets nucléaires à travers le monde pour les années à venir, cela sous différentes

Low-Latency Message Communication Support for the AP1000

[1992] Proceedings the 19th Annual International Symposium on Computer Architecture, 1992
Low-latency communication is the key to achieving a high-performance parallel computer. In using state-of-the-art processors, we must take cache memory into account. This paper presents an architecture for low-latency message comunication and implementation, and performance evaluation.

The AP1000 reactor?the nuclear renaissance option

Nuclear Energy, 2004
The AP1000 is a two-loop, 1150 MWe pressurised water reactor (PWR) with passive safety features and extensive plant simplifications to enhance construction, operation and maintenance. The AP1000 design is derived directly from the AP600, a two-loop, 600 MWe PWR. The AP600 uses proven technology, which builds on over 30 years of operating PWR experience

QCD ON THE MASSIVELY PARALLEL COMPUTER AP1000

International Journal of Modern Physics C, 1993
We present the QCD-TARO program of calculations which uses the parallel computer AP1000 of Fujitsu. We discuss the results on scaling, correlation times and hadronic spectrum, some aspects of the implementation and the future prospects.

The parallelization of the incomplete LU factorization on AP1000

1998
Using a finite difference method to discretize a two dimensional elliptic boundary value problem, we obtain systems of linear equations Ax=b, where the coefficient matrix A is a large, sparse, and nonsingular. These systems are often solved by preconditioned iterative methods.

QCD on the highly parallel computer AP1000

Nuclear Physics B - Proceedings Supplements, 1992
Abstract We have been running quenched QCD simulations on 32 4 and 32 3 × 48 lattices using a 512 processor AP1000, which is a highly parallel computer with up to 1024 processing elements. We have developed programs for update, blocking and hadron propagator calculations.

Improvement of the Reactor Control System in AP1000

Volume 1: Operations and Maintenance, Engineering, Modifications, Life Extension, Life Cycle and Balance of Plant; I&C, Digital Controls, and Influence of Human Factors, 2017
AP1000 is a two-loop pressurized water reactor (PWR) developed by Westinghouse, which uses the forces of nature and simplicity of design to enhance plant safety and reduce construction costs. Compared to traditional reactor control strategies, the AP1000 adopts an advanced Mechanical Shim (MSHIM) core control strategy, which controls the reactivity and

Off-Site Emergency Response of AP1000

Volume 3: Nuclear Safety and Security; Codes, Standards, Licensing and Regulatory Issues; Computational Fluid Dynamics and Coupled Codes, 2013
Considering the emergency evacuation of Fukushima, special attention shall be paid on the reasonableness of the emergency evacuation area and the population distribution in the site vicinity. Based on the radioactive release source of AP1000 in the event of a severe accident, this paper proposes the classification of emergency area of AP1000 and ...
