Abstract

The invention relates to the technical field of equipment stability testing, and discloses a CPU pressure testing method and device. The method comprises the following steps: after a test starting instruction sent by a management board is received, the number of CPU cores for testing being determined according to the total number of CPU cores included in a CPU of a board card of the CPU cores andthe CPU utilization rate in a no-load state; selecting the CPU cores with the number of the CPU cores for testing from the total number of the CPU cores; adopting the selected CPU kernel to run the pressure test program within a set test duration to obtain a running result of the selected CPU kernel; and determining a first test result of the CPU of the own board card according to the obtained operation result. In the embodiment, a part of CPU cores are reserved for system operation, so that the stability of the system is maintained, a CPU high-load operation environment is constructed in a mode of enabling the other part of CPU cores to operate a pressure test program, the defect of full-load test is avoided, a plurality of board cards can be tested at the same time, and the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of equipment stability testing, in particular to a CPU stress testing method and device. Background technique [0002] The existing CPU (central processing unit, central processing unit) stress test method refers to the CPU full-load test, specifically, refers to running the stress test program to run the CPU utilization rate to full (100%), and running continuously for a long time. During the period, check whether the device has problems such as blue screen, crash and restart. The existing CPU stress test method is suitable for single-board testing of single-CPU devices. [0003] The rack-mounted device includes multiple boards, and each board includes a CPU, and each CPU senses communication to run a distributed system. In the CPU stress test process of rack-mounted equipment, if the existing CPU stress test method is used to test one board at a time, the test cycle will be longer, which seriously affects...
