Abstract

The invention provides an algorithm conversion method and system in a heterogeneous many-core processor, and the technical scheme of the method comprises the steps: predefining a data structure of a C + + algorithm recognition library in a main core of the heterogeneous many-core processor, predefining a statement recognition rule and a grammar mapping rule for converting a C + + algorithm into a C language, and carrying out the grammar analysis of a C + + source code through an ANTLR technology, forming an abstract syntax tree; traversing the abstract syntax tree, analyzing a C + + algorithm definition file, and constructing an algorithm recognition library according to a data structure of a predefined C + + algorithm recognition library; traversing the abstract syntax tree again, and mapping a C + + source code algorithm statement to a libcstl based on a C language according to a syntax mapping rule; and reconstructing the C + + source code algorithm statement according to the grammar rule of the libcstl, and converting the C + + algorithm into the libcstl of the C language. The problems that an existing STL algorithm is complex in implementation and complex and time-consuming in reconstruction, and a manual writing mode is low in efficiency and high in cost are solved.

Description

technical field [0001] The invention belongs to the field of ANTLR grammar analysis, and in particular relates to an algorithm conversion method and system in a heterogeneous many-core processor. Background technique [0002] The "Sunway*Light of Taihu Lake" supercomputer uses domestic SW26010 heterogeneous many-core processors, such as figure 2 As shown, the processor adopts a master-slave core architecture. A processor contains 4 core groups (CGs), and each core group contains 1 master core (MPE), 1 8*8 slave core array (CPE) and 1 memory controller (MC), the peak computing power of a single processor is 3TFlops, and the memory access bandwidth is 130GB / s. The main core compiler supports three programming languages: C, C++ and Fortran, while the slave core compiler only supports two programming languages: C and Fortran. Compiler incompatibilities make scientific computing programs written in C++ unable to run directly on the slave core, thus making it impossible to effec...
