example

[0034] During the operation of the computer system, the first program is first called, and the first program is executed after a response is obtained. During the execution of the first program, the second program needs to be executed preferentially. At this time, the first program is interrupted, and then the process information related to the first program in the memory is stored in the hard disk by using the BLCR library, and the interrupt is responded to, and the above-mentioned interrupted breakpoint is loaded into the stack of the computer system, and then generated Interrupt vector address. Then, after the execution of the second program is completed, it is necessary to continue to execute the first program. At this time, restore the process information from the hard disk to the memory, and continue to execute from the place where the first program was interrupted according to the interrupt vector address generated above. Thus, the recovery process of the first program...

Abstract

The invention provides a method for recovering a process of a computer system. The method comprises the following steps of: S1, interrupting a first program; S2, storing the process information of the first program in a memory into a hard disk in a Berkeley lab checkpoint / restart (BLCR) mode, and filling an interrupted breakpoint into a stack; and S3, recovering the process information in the hard disk to the memory. According to the method for recovering the process of the computer system, the program process of the computer system can be timely stored and recovered, and the running stability and the running security of the computer system are ensured.

Description

technical field [0001] The present invention basically relates to the computer field, and more specifically, relates to a computer system process recovery method. Background technique [0002] In a high-performance computing environment, many user jobs need to run for a long time. In this case, the longer the user job runs, the greater the risk of job failure and the greater the loss. In the event of a job crash, the user can only resubmit the job to run. Utilizing the process on-site storage and recovery technology, it can ensure that the user's job information exists in the physical medium in the form of a mirror image after the node fails, and the job process can be quickly restored after the operating environment is restored. [0003] The prior art provides a data backup method, which is applied to a device management system, the device management system includes a device terminal and a device management server, and the device management server is used to maintain and m...
