Task scheduling method and service system

Abstract

The embodiment of the invention provides a task scheduling method and a service system. The service system comprises a task scheduling unit, a resource management unit and a plurality of computing units. The resource management unit pre-stores the corresponding relation between the identification information of the computing unit, the algorithm type of the task executable by the computing unit and the available resource number of the computing unit; if the task is to be executed, the task scheduling unit sends a query request to the resource management unit; the resource management unit queries the number of available resources of the computing unit capable of executing the to-be-executed task according to the stored corresponding relation; and if the available resource number of the computing unit capable of executing the to-be-executed task is not less than the resource number consumed by the to-be-executed task, the task scheduling unit sends the to-be-executed task to the computing unit for execution. And when the task needs to be executed, the task scheduling unit sends the query request to the resource management unit, so that the interaction pressure of the resource management unit is reduced, and the service performance of the service system is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a task scheduling method and service system. Background technique [0002] With the development of cloud computing, big data and other technologies and the maturity of service systems such as cloud platforms, more and more tasks are migrated to the service system for execution. With the increase of tasks in the service system, how to scientifically schedule many tasks , The rational allocation of resources has become the core of the service system. [0003] Such as figure 1 As shown, the current service system includes a resource management unit and multiple computing units. The resource management unit is used to manage the resources provided by each computing unit in the service system. The computing unit is used to perform specific tasks. The computing unit actively A task execution request is sent to the resource management unit, wherein the task execution reque...

Problems solved by technology

[0004] It can be seen that as long as the computing unit has idle resources, it will send a task execution request to the resource management unit. As the number of computing units becomes larger and larger, each computing unit will actively send a task execution request to the resource management unit when there are idle resources. This undoubtedly increases the interaction pressure of the resource management unit, resulting in poor service performance of the service system
