Cluster task resource allocation method for multi-core processor

Abstract

The invention relates to a cluster task resource allocation method for a multi-core processor. In the method, CPU resource nodes are used as basic allocation units for task allocation according to operation tasks submitted by receiving users to a cluster, and a task resource allocator is formed. The task resource allocator maps resources on the cluster to an M*N matrix AR. When idle resource positions are searched for the tasks, in the method, the tasks are uniformly dispersed and required resources are allocated to the nodes, so that the resource node positions occupied by all tasks are spaced. The method avoids the problem that tasks are excessively concentrated in one certain area, a large amount of heat energy is concentrated in the area as time goes by, the temperature of a local chip is too high, and the normal operating efficiency of a computer is influenced in the traditional task allocation algorithm. The task scheduling algorithm adopted by the method is an online real-time task scheduling algorithm and has good application prospects in the operation and task management of a multi-core processor cluster system.

Description

technical field [0001] The invention relates to a multi-core processor cluster task resource allocation method, which belongs to the technical field of high-performance computing and computer clusters. Background technique [0002] As integrated circuits enter deep submicron and nanometer processes, the design of multi-core processors faces a series of new problems, among which power consumption is a crucial aspect. The power consumption of the processor not only affects the packaging, testing and system reliability of the chip to a large extent, but also determines the development of the system on chip and mobile devices to a large extent. The heat generated by the CPU has begun to seriously affect the CPU Increase in frequency. [0003] On a cluster system composed of multi-core processors as computing nodes, the problem of heat dissipation has always been a big problem. Traditional heat dissipation technologies mainly include CPU fans, air conditioners, and liquid cooli...
