Abstract

The invention provides a multi-node system kernel code reading method and system. The system comprises a first node working as a main node, and further comprises at least one second node. The method comprises steps that the first node reads a kernel code segment in a kernel image from a first memory address; the first memory address is a preset address of a local memory of the first node; the first node sends the kernel code segment to the local memory of the second node; and when the second node needs to operate the kernel code, the second node reads the kernel code from the local memory of the second node. According to the technical scheme, kernel code reading speed can be improved and multi-node system performance can be enhanced.

Description

technical field [0001] The invention relates to computer technology, in particular to a method and system for reading kernel codes of a multi-node system. Background technique [0002] With the continuous improvement of computer performance requirements for scientific computing and transaction processing, Symmetric Multiprocessor (Symmetric Multi Processor, referred to as SMP) system is more and more widely used, and its scale is also increasing. [0003] A Non Uniform Memory Access (NUMA for short) system consists of multiple nodes connected through a high-speed interconnection network, and each node can access all system memory with different delays. In addition to local memory, the NUMA system also has remote memory, which is distributed among other nodes. The latency of the CPU accessing local memory and accessing remote memory is different, and accessing remote memory is slower than local memory. [0004] Each node of the NUMA server is composed of multiple central pr...
