Abstract

The invention discloses a method and a device for server task scheduling. According to the type of tasks, the tasks are distributed to a pre-bound task group, and a preset task scheduling algorithm corresponding to the pre-bound task group is used for scheduling the tasks, wherein the pre-bound task group comprises a first preset quantity of CPUs (Central Processing Units), and is bound with a memory bank which contains a preset second quantity of memory nodes. Different types of tasks are distributed to different task groups, the task group contains a corresponding quantity of CPUs and memory nodes, and the CPUs and the memory nodes are grouped to execute of different types of tasks; and when task scheduling is carried out, the characteristics of the task are considered, and the hardware characteristics of the CPU and the memory node of the server are also considered. During task scheduling, the hardware characteristics of the server are considered, and performance loss brought by task switching can be reduced so as to improve the resource use ratio of the server and improve server performance. Obviously, the method is favorable for improving the server performance.

Description

technical field [0001] The present invention relates to the technical field of server RAS, in particular to a method and device for server task scheduling. Background technique [0002] With the development and progress of computer technology, new requirements are put forward for the performance of servers. [0003] In terms of server hardware, multi-channel multi-core CPU is the continuous development direction of CPU technology, while non-uniform memory access architecture (NUMA) technology is the mainstream for memory. Servers can perform a variety of tasks, tasks can be divided into computing-intensive tasks and I / O-intensive tasks. Computing-intensive tasks can refer to tasks with high CPU usage, such as calculation and logic judgment. Frequent switching of computing-intensive tasks will reduce CPU utilization. I / O-intensive tasks can refer to tasks such as frequent network transmission, reading hard disks, and other I / O devices. Since the CPU is in a waiting state mo...
