AI Technical Summary

Problems solved by technology

However it can be very expensive for low priority tasks
This termination-based preemptive scheduling method not only increases the response time of low-priority tasks, especially low-priority tasks that need to run for a long time, but also consumes a lot of resources and greatly weakens the performance of the entire cloud.
[0005] Aiming at the problems of long response time, high resource consumption, and low cloud work efficiency of low-priority tasks in the existing technology, no effective technical solutions have been proposed yet

Abstract

The invention discloses a task scheduling method and device for shared clusters. The method comprises the steps that resources and scheduling parameters in the shared clusters are determined; whether a check point needs to be set or not is checked in a timed mode; when the check point needs to be set, a task for setting the check point is determined, and the check point is set; when a new task is reached, a running task and mixed waiting queue is updated; when the resource using condition of the shared clusters changes, the running task and mixed waiting queue is updated. The low-priority task responding time can be shortened, the resource utilization rate can be increased, and then the overall cloud performance is improved.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a task scheduling method and device for a shared cluster. Background technique [0002] With the development of modern data centers, cloud computing technology is becoming more convenient and influential. Multiple commercial cloud platforms can provide consumers with a pay-as-you-go method, and consumers can directly deploy programs on the cloud platform without considering the cloud architecture. This approach is indeed very convenient for consumers, but it also brings some management challenges for cloud service providers. [0003] Shared clusters make cloud computing platforms a reality. It is worth noting that most commercial cloud platforms, including Google and Microsoft, use a preemptive task scheduling method to solve the problem of insufficient resources occurring in the cluster. Generally speaking, the priority of the task is included in the attached attributes ...
