Embodiment Construction

[0015] Such as figure 1 As shown, the following definition is made:

[0016] JobTracker: check the overall task scheduling center

[0017] TaskTracker1: check the executor of subtask 1

[0018] TaskTracker2: check the executor of subtask 2

[0019] :

[0020] :

[0021] :

[0022] TaskTrackerN: check subtask N executor

[0023] When the check starts, define a unique check ID for each check, and divide the check task into different subtasks according to certain rules. These subtasks are relatively independent during execution and have the same checkmark. The JobTracker mastered in Hadoop distributes these subtasks to idle TaskTrackers (divided into TaskTracker1 for checking subtasks, TaskTracker2 for checking subtasks for checking...TaskTrackerN for checking subtasks), allowing these tasks to run in parallel. After the parallel calculation is completed, the results with the same verification flag are integrated together as the final result. The process of data integrat...

Abstract

The invention discloses an online checking method of parallel computing in an electrical power system. The method comprises the following steps of (1) building a Hadoop environment; (2) initializing Hadoop-based online check tasks; (3) deposing the online check tasks; (4) executing the online check tasks in parallel; (5) combining and computing each online check task. Due to the fact that Hadoop, i.e. a software frame which can process a large amount of data in a distributing way, is applied to online check of parallel computing in the electrical power system, the problem that too much time is used for large data numerical computing is solved, and the speed of online check computing is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to an online checking method for parallel computing in the power system. Background technique [0002] With the continuous development of the power industry, the scale of the power system is expanding day by day, the structure of the power grid is becoming more and more complex, and the amount of calculation and the complexity of calculation are increasing sharply. The traditional calculation method can no longer meet the requirements of the power system in terms of calculation speed and space. In traditional parallel computing, HPC (High Performance Computing, high-performance computing) clusters transmit data from data nodes to computing nodes through data buses or networks, which can easily cause I / O bottlenecks. [0003] Hadoop (The name Hadoop is not an acronym, it is a made-up name. Doug Cutting, the project's creator, explained how Hadoop got its ...
