Embodiment Construction

[0017] This pipeline method for implementing concurrent programming in P language includes the following steps:

[0018] 1) Determine the functional unit of the code based on the self-made P programming language framework of concurrent programming;

[0019] 2) Estimate the number of cycles spent in the core;

[0020] 3) The code executes a section of initial code that fills the pipeline;

[0021] 4) The core executes most of the iterations of the loop in an interleaved fashion;

[0022] 5) If the process fails, increase the size of the core by 1 and try again;

[0023] 6) After the loop kernel is completed, execute the corresponding epilogue code to complete the last iteration.

Abstract

The invention discloses a streamline method realizing P language concurrent programming; the method comprises the following steps: determining a code function unit according to a concurrent programming self made P programming language framework; estimating period numbers consumed in a core; the code executes an initial code filling the streamline; the core executes most cycling iterations in a staggering mode; if the processing fails, adding 1 on the core and retry; executing corresponding ending code so as to complete the final iteration after cycle core finishes.

Description

technical field [0001] The invention relates to a pipeline method for realizing concurrent programming of P language Background technique [0002] Programming language develops from assembly language, to procedural language, to object language, and to higher-level languages. The higher the degree of abstraction, the lower the operating efficiency will be. The processing of big data, especially the processing of multimedia data, requires more and more calculations, which requires the abstraction of programming languages ​​and higher requirements for the efficiency of programming languages. [0003] Parallel computing refers to the existence of more than one computing task being executed at the same time. Due to the upper limit of the increased processor frequency, the use of multi-core processors for parallel computing has become the mainstream. API (Application Programming Interface) are predefined functions designed to provide applications and developers the ability to ac...
