Serial program parallelization method based on marks

Abstract

The invention relates to a serial program parallelization method based on marks. The serial program parallelization method comprises the following steps that (1) serial programs are marked; (2) analyzing the mark by a code analysis system, and recording mark clause parameters; (3) enabling the code parsing system to extract parallel code segments from a basic parallel code library and filling theparallel code segments with marked clause parameters; (4) splicing the filled parallel code segments to obtain a parallel program corresponding to the final serial program. According to the method, the parallel programming development cost is reduced, and the burden of developers is reduced; the parallelization capability of a plurality of platforms is provided, and the parallel APIs of a plurality of parallel platforms can be obtained by one serial API; a special compiler does not need to be developed independently, a mature compiler can be directly adopted, and the parallel compiling efficiency is high. According to the method based on marking, an original program is not rewritten, a serial program does not need to be deeply understood, the reliability of parallel programs is improved through the standardized marking analysis process, and the error probability is reduced.

Description

technical field [0001] The invention relates to a parallel program generation method, in particular to a serial program parallelization method. Background technique [0002] With the development and popularization of parallel computing technology, there are a large number of serial applications in the industry that urgently need to be transformed into parallel programs to improve data processing capabilities. The parallelization of serial programs faces two basic problems: (1) The high cost of parallel programming. Parallel programming requires professional parallel programming capabilities and rich engineering experience, and the development of parallel programs requires a lot of engineering costs and time. (2) Diversity of parallel platforms. With the increase and diversification of various parallel hardware platforms and parallel programming models, it is necessary to have the ability to quickly generate parallel programs for the desired target parallel platform. In vi...
