Embodiment Construction

[0084] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0085] 1) Implementation of Algorithm Framework

[0086] In a multi-scale discrete system, in principle, the upper-level unit will have constraints and influences on the lower-level units that make it up, making it different from completely independent individual behaviors. and regulatory constraints. So any simulation that reflects this reality naturally needs to establish a feedback-constraint mechanism with the upper units. At the same time, there will also be adjacent interactions among upper-level units, such as cooperation and competition between units and countries, and between countries in human society. Furthermore, this kind of relationship can be nested, that is, there are multi-level upper and lower unit rel...

Abstract

The invention relates to the technical field of high-performance computers, and discloses a concurrent computational system for multi-scale discrete simulation. In respect to the multi-scale structure and discrete characteristics of the complex system in the real world, the system maintains the consistency and similarity among simulation object, computation model, frame of algorithm and computer architecture. The system describes the local behavior of the systems in different layers with a large number of adjacent discrete units and describes the collective behavior of the systems in different layers with long-range restraint and correlation, and two-way feedback is applied between the upper layer unit and the lower layer unit. Correspondingly, the special reconfigurable vectorized accelerator group is used as the bottom layer computation hardware, the universal processor array is used as the upper layer computation hardware, and the adjacent processors or accelerators in the same layer can directly communicate or share memory with the processors or accelerators in the part of adjacent layers. Therefore, the system can efficiently and truly simulate complex process and system.

Description

technical field [0001] The invention relates to the technical field of high-performance computer numerical simulation, in particular to a parallel computing system oriented to multi-scale discrete simulation. Background technique [0002] Computer simulation has become the third basic method of scientific research and technology development alongside theory and experiment, and it is also the main application direction of high-performance computing. Mechanistically realistic and practical models; the accuracy of calculation methods is increasingly incompatible with the complexity of simulated objects; the gap between the peak speed of computers and actual computing power is getting bigger and bigger; the popularity of high-performance computing and The demand gap for high performance computing is widening. [0003] In order to deal with the above challenges, it is first necessary to propose a mechanistic model that can reflect the basic characteristics of the complex system,...
