Embodiment Construction

[0033] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the present invention, but are not intended to limit the present invention.

[0034] The big data system can collect and analyze data, which is mainly reflected in the acquisition and comprehensive analysis of various data of the basic application system. For the acquisition, analysis and synthesis of these data, tasks need to be created and reasonably scheduled. For the diverse tasks and computing nodes whose status changes at any time in the big data system, how to perform task scheduling is crucial; computing nodes are located in the same and different hardware devices, and are connected to each other by bus, internal line or network connection; scheduling The node is used to create a task based on the task creation request submitted by the terminal device, and schedule...

Abstract

The invention relates to a task scheduling method and system based on a big data system. The method comprises the following steps: creating a task based on a task creation request; calculating a task feature matrix, and putting the tasks into a task pool; obtaining an available computing node set; selecting a target task set from a task pool based on the available computing node set; and assigning tasks in the target task set to the available computing node set. According to the method, task scheduling is performed based on matching of the sets, so that the task scheduling flexibility is improved, the task scheduling can be locally optimal under the condition that real-time performance is allowed, complex feature description becomes possible under the condition that the calculated amount is limited, and the task scheduling efficiency is improved. And the task scheduling efficiency in the big data system environment is greatly improved.

Description

【Technical field】 [0001] The invention belongs to the field of big data, and in particular relates to a task scheduling method and system based on a big data system. 【Background technique】 [0002] With the advancement of science and technology, the development of information has entered the era of big data, and data medical care is an important field of big data. With the rapid development of medical information technology, more and more medical institutions in China are accelerating the implementation of information-based platforms. Overall construction to improve the service level and core competitiveness of the hospital. With the launch of the new medical reform, the application of big data has exploded. When the rapidly growing and diverse hospital data encounters big data technology, medical big data applications are quickly welcomed by medical institutions. Large hospitals basically have hundreds of systems running online, so when the hospital informatization center...
