Embodiment Construction

[0032]The parallel programming model system and method for DAG data-driven application of the present invention, such as figure 1 As shown, it consists of three modules: user application module, DAG schema module and DAG runtime system module.

[0033] The user application program module is used to use some basic steps and contents set by the user as the drive of the entire parallel programming model system and method. In the design and implementation of this module, the user only needs to do some simple initialization settings and specific algorithm applications, and parallel programming can be realized automatically. The processing steps of the user application module include:

[0034] First, the user selects a DAG pattern diagram from the DAG pattern gallery according to the needs of his application (if the DAG pattern diagram provided by the system cannot meet the needs of the user application, the user can implement his own DAG pattern diagram and add it as needed. To t...

Abstract

The invention discloses a parallel programming model system of DAG oriented data driving type application and a realization method. The parallel programming model system of DAG oriented data driving type application comprises a DAG mode chart module, a user application program module and a DAG runtime system module, wherein the DAG mode chart module comprises a DAG mode chart bank; the user application program module is used for user initialization setup and confirmation of specific parallelization algorithm; and the DAG runtime system module comprises a main thread and a thread pool. The main thread is used for analyzing and updating the DAG mode chart, issuing and dispatching data block, and controlling fault-tolerance; the thread pool comprises a thread pool queue buffer zone and a work thread, wherein the thread pool queue buffer zone is a data interface for the main thread and the work thread, the work thread is used for constantly acquiring computing tasks from the queue buffer zone and carrying out computing. Compared with the prior art, the invention decreases difficulty in designing and developing a parallel computing application program for non-computer professionals, shortens development period of parallel software, and enables the completed parallel computing application program to have more reasonable structure and more optimized performance.

Description
