Abstract

The invention discloses a multi-level parallel programming method and relates to the field of parallel programming model, mode and method. The method fully combines the characteristics of a mixed hardware architecture, has obvious effect of improving the utilization rate of a group hardware environment, helps developers simplify the parallel programming and multiplex the existing parallel codes, reduces the programming complexity and the error rate through inter-process and intra-process processing and further reduces the error rate by taking fault tolerance into full consideration.

Description

technical field [0001] The invention relates to the field of parallel programming models, patterns and methods, in particular to a multi-level parallel programming method. Background technique [0002] With the continuous expansion and improvement of the application range and application level of computers, people's requirements for computing and processing capabilities of computers have also increased. In the field of scientific and engineering computing such as exploration and mathematics, due to the increase in the amount of data calculation and the increase in computational complexity, the solution process of many practical application problems constantly puts forward new requirements in terms of computing power and computing speed. The need is more and more urgent. Most of these practical applications are data-based, and time-consuming calculations are mainly numerical calculations. [0003] At present, in terms of hardware, with the emergence of multi-core processors...
