Problems solved by technology

[0004] However, the existing scheduling methods do not take into account the aging problem of the execution node support platform
Existing availability scheduling methods are mainly completed by replicating or allocating more reliable computing resources and network resources for key tasks. However, due to software aging, resources with strong computing capabilities will inevitably experience performance degradation or even crash during operation. , affecting the actual performance of the task

Abstract

The invention provides an aging perception task scheduling system. The aging perception task scheduling system comprises an aging detection module, a software regeneration module, a task scheduling module, a scheduling policy module and a resource information base module; the aging detection module and the resource information base module are in both-way connection, the resource information base module is in one-way connection with the software regeneration module and the task scheduling module, and the scheduling policy module is in one-way connection with the task scheduling module. According to the aging perception task scheduling system, in the task scheduling and running process, the aging state of resource nodes can be perceived in real time, the service capability of the resource nodes can be recovered in real time, and the task execution efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of computers, in particular to an aging-aware task scheduling system. Background technique [0002] Studies have shown that when software runs continuously for a long time, the accumulation of some internal error conditions will cause software performance to decline or even stop running. This phenomenon is called software aging. Software aging is especially common in systems that need to run for a long time, such as virtual machines and hypervisors, operating systems, cloud platform system software, and more. In order to reduce or even eliminate the risks brought by software aging, people have proposed a method called software regeneration, which can evaluate the aging status of the system in time and take restart operations in due course to improve system reliability. How to choose the timing of regeneration is the key to eliminate the risk of software aging. If regeneration is too early, the cost will be ...
