Abstract

The invention discloses a method for automatically parallelizing a program. The method comprises the following steps of: (1) acquiring a source program and acquiring a parallel part comprising a cyclic part and a branch part by analyzing the source program; (2) dividing the parallel part in the source program into a plurality of parallel modules, wherein the parallel modules are allocated to different processors for processing through threads; and (3) compiling the source program subjected to parallel extension into an executable code. The method has the advantages of providing a simple program parallelizing environment, fully designing the unique advantages in aspects of simplicity, safety and portability, achieving extremely high operating safety and reusability during development, greatly reducing multi-platform development cost, fully utilizing hardware resource, improving program performance and quickening a computation process.

Description

technical field

[0001] The invention relates to the field of parallel program design and compiler design, in particular to a method for automatic parallelization of programs. Background technique

[0002] At present, the number of computer cores is increasing continuously. To reflect the advantages of multi-core, it is necessary to make full use of multi-core hardware resources, so it is necessary to realize multi-core parallel computing. Parallel programming is a good implementation method, but parallel programming is difficult, which makes it difficult for programmers who are accustomed to serial programming to adapt to parallel programming mode. The difficulty of parallel programming is that it is difficult for programmers to determine where to implement parallelism in the program, and the height of multi-threaded parallel programs is very troublesome. The processing of data dependencies between threads and the choice of parallel level all affect parallel programming. If...
