Modal parallel computing method and system for heterogeneous many-core parallel computer

Abstract

The invention provides a modal parallel computing method and system for a heterogeneous many-core parallel computer. The method comprises the following steps: the step S1: generating a finite elementmodel rigidity matrix and quality matrix data through a finite element program, dividing the generated finite element model rigidity matrix and quality matrix data into N subareas, and independentlystoring the finite element model rigidity matrix and quality matrix data of each area in a file, wherein N is an integral multiple of a single core group; and the step S2, enabling the main cores of the core groups which are subjected to parallel computing to synchronously read the finite element model rigidity matrix and the quality matrix data corresponding to the sub-regions, enabling the coregroups to have no data communication exchange, and enabling the slave cores in the core groups to have no data communication exchange. Layering of the calculation process and data communication is achieved through a layering strategy, a large amount of data communication is limited in each core group, and the advantage that the communication rate in the domestic heterogeneous many-core parallel computer core group is high is fully played.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a modal parallel computing method and system for heterogeneous many-core parallel computers. Background technique [0002] With the development of the transportation industry, energy exploration and development industry, and aerospace industry, there is an increasing demand for large and extra-large equipment, such as: high-speed EMUs, 3000m ultra-deep drilling rigs, large aircraft, cross-river tunnels, etc. . The development of these special equipment systems often involves the calculation of large-scale complex dynamic systems, and modal analysis is the most time-consuming calculation link, and it is also the basis of the rest of the calculation links. Large-scale finite element models are needed for high-performance calculations. Therefore, it poses a challenge to the traditional serial finite element calculation methods and tools. Traditional serial computing is to simpli...
