Embodiment Construction

[0045] A method for troubleshooting the CPU failure of a multi-channel many-core server according to the present invention will be described in detail below in conjunction with the accompanying drawings.

[0046] like figure 1 As shown, a kind of method for troubleshooting multi-channel many-core server CPU failure of the present invention is by analyzing the mcelog record file and the cpuinfo file that comes with the linux system, and resolves the logic cpu of the failure recorded in the mcelog to the physical cpu, and then passes Swap the location of the faulty CPU, and at the same time perform a stress test on the CPU and memory to locate the fault.

[0047] An enterprise purchased Inspur TS850 fully configured server, which is configured with 8 physical CPUs, each with 8 cores, and without hyper-threading technology, its logical CPUs can reach 64 cores.

[0048] A crash occurs in the application, and an error message appears in / var / log / mcelog at the same time, but the cp...

Abstract

The invention provides a method for checking a multi-path many-core server CPU (Central Processing Unit) fault. The method is characterized in that through resolving a mcelog record file and a cpuinfo file in a linux system, a logic CPU of the fault recorded in mcelog is resolved into a physical CPU; then, through the CPU position exchanging and the great-pressure test on the CPU and a memory, the fault is located. Compared with the prior art, the method for checking the multi-path many-core server CPU fault has the advantage that the fault problem of the CPU can be timely and fast discovered. The method also has the characteristics that the design is reasonable; the structure is simple; the processing is easy; and the use is convenient, and the like. Therefore the method has good application values.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for troubleshooting CPU faults of multi-channel many-core servers. Background technique [0002] At present, with the popularity of multi-channel servers, a large number of servers composed of multiple physical CPUs, such as four-way servers and eight-way multi-core servers, have appeared in enterprise-level applications, and the troubleshooting of communication between CPUs and memory is a complicated technology. question. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a method for troubleshooting the CPU failure of a multi-channel many-core server. [0004] The technical solution of the present invention is realized in the following manner, in its structure, by parsing the mcelog record file and the cpuinfo file that comes with the linux system, the logical cpu of the fault recor...
