Embodiment Construction

[0029] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0030] The method for realizing the heartbeat detection in the SMP system of the invention is used for detecting the state of the CPU in the SMP system. Heartbeat detection refers to a method in which two or more independent units send agreed heartbeat messages through some means of communication to monitor the survival status of each unit. In the present invention, a certain CPU is designated as a collector of heartbeat messages among multiple CPUs in the SMP system, which is called the collecting CPU; other CPUs in the SMP system except the collecting CPU are called monitored CPUs. The monitored CPU sends a heartbeat message to the collecting CPU, and the collecting CPU collects and analyzes the heartbeat message according to actual needs, and generates a heartbeat detection result.

Abstract

The invention discloses a method for testing heartbeat which comprises the following processes: an idle task is arranged to be used for sending heartbeat messages; the idle task is called to send the heartbeat messages to a collection center processor unit (CPU). The invention also provides a heartbeat testing system and the CPU to be applied in a symmetrical multi-processing (SMP) system to realize the state detection of the CPU in the SMP system. The initial priority of the idle task adopted by the invention is low priority and the priority of the idle task can be adjusted according to actual requirements, thus ensuring that the heartbeat testing has a relatively high real-time performance under the situation that the utilization rate of internet resources in the SMP system is guaranteed.

Description

technical field [0001] The invention relates to equipment state detection technology, in particular to a heartbeat detection method, system and central processing unit. Background technique [0002] With the continuous development of computer technology, the requirements for computer processing capabilities in practical applications are also getting higher and higher. At present, more and more computers adopt the composition structure based on Symmetric Multiprocessing (SMP, Symmetric MultiProcessing) system to achieve High processing power requirements. The SMP system is composed of multiple central processing units (CPU, Central Processing Units) coupled and connected to a high-speed bus, which can perform concurrent processing of multiple tasks, which is beneficial to improve the performance of the computer. [0003] Since the SMP system is composed of multiple CPUs, in practical applications, the SMP system needs to monitor the living status of each CPU in real time, bu...
