Title: CHECKPOINT CREATION METHOD, DEVICE AND SYSTEM
Abstract:
An embodiment of the present invention provides a method, device and system for creating a checkpoint, wherein the method comprises: reading a T1 process number recorded by a process number register at a first time, determining that a process indicated by the T1 process number is used for executing a checking program, wherein the process number register holds a process number of a process currently being run by a function simulator, and at least one basic block resulting after running the function simulator is sent to a performance simulator for execution; reading a T2 process number recorded by the process number register at a second time, determining that a process indicated by the T2 process number is used for executing a checking program; creating a checkpoint and recording checkpoint data, wherein the checkpoint data comprises a snapshot of the function simulator and state information of the performance simulator. The technical solution disclosed by the embodiment of the present invention can increase the accuracy of the checkpoint data, thereby improving the checking accuracy of the simulator.
