Embodiment Construction

[0109] Specific embodiments of the present invention are given below, and the present invention is described in detail in conjunction with the accompanying drawings.

[0110] The invention discloses an optimization method for online iterative compilation, which includes the following steps:

[0111] Step 100, the control module sends the source code of the corresponding program or the form of the intermediate representation further optimized by the compiler to the working module, and predicts that the remaining data will be processed during the parallel processing of the data records stored in the working module by the program record the time required;

[0112] Step 200, the working module iteratively compiles and optimizes the program, and feeds back the optimization result data to the control module;

[0113] Step 300, storing the running time of the program and the time spent on iterative compilation and optimization operations in a performance database, and the performance ...

Abstract

The invention discloses an optimization method and an optimization system of on-line iteration compiling. The optimization method comprises the following steps that 100 a control module sends a source code or a compiler of the corresponding program in a mode of further optimized intermediate representation to a working module, and needed time of remaining data recording after processing is forecasted in a process that the program parallely processes the data recording stored in the working module; 200 the working module conducts iteration compiling optimization operation on the program and enables data of optimization results to be fed to the control module; and 300 operation time of the program and time of the iteration compiling optimization operation are stored in a performance data base which is used for storing pay expenses and income of all iteration compiling optimization operation to supply to the control module for use.

Description

technical field [0001] The invention relates to computer compilation technology, in particular to an optimization method and optimization system for online iterative compilation. Background technique [0002] Iterative compilation technique [1, 2, 3, 4, 5, 6, 7, 8, 9] is a simple but effective optimization method. It improves the performance of a given computer program in a given computer hardware and software environment by searching for the best combination of compiler optimizations. However, the best optimal combination for different computer programs or even different inputs to the same computer program may be different. Therefore, existing iterative compilation techniques are limited by the following problems and have not been widely used: [0003] 1. Finding the best combination of optimizations requires a lot of compilation and test runs. [0004] Second, iterative compilation The process of selecting the optimal combination depends on the data set of the computer ...
