Embodiment Construction

[0061] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0062] Secondly, the present invention is described in detail by means of schematic diagrams. When describing the embodiments of the present invention in detail, for convenience of explanation, the schematic diagrams are only examples, which should not limit the protection scope of the present invention.

[0063] The inventor found in practice that there are some variables, namely: thread invariants, which are consistent in each parallel thread executed by merging, and data expansion may not be performed on such variables, s...

Abstract

The invention discloses a data expanding optimization method of merging execution large-scale parallel thread. The data expanding optimization method of merging execution large-scale parallel thread comprises that a thread invariant in a parallel thread is distinguished in the process of merging execution; the thread invariant is stayed the same in each parallel thread in the process of merging execution; in the compilation process, a non-thread variant is data expanded. The data expanding optimization method of merging execution large-scale parallel thread reduces unnecessary thread private data expansion, is capable of remitting severely expanding of stack space after the process of merging and improves execution efficiency of a program.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data expansion optimization method for merging and executing large-scale parallel threads. Background technique [0002] In recent years, multi-core and many-core architectures have developed rapidly, providing application developers with increasingly powerful computing capabilities. Developers of commercial software are keen to use various mature parallel processors on the market to develop high-parallel applications. software. However, an application program with a specific parallel granularity and implementation method cannot be well adapted to various parallel processing platforms, so a powerful parallel programming model and compilation tool support are needed to effectively utilize the characteristics and capabilities of each parallel processor . A lot of research work has been carried out based on this, for example, Hybrid Multicore Parallel Programming workbench (HMPP, Hybrid...
