Abstract: A method and apparatus for adjusting a checkpoint are provided. The method includes monitoring calls of an application program interface (API) that are called when an accelerator device executes an application, and by the monitoring, checking an API execution logic and a current API execution cycle of the application with respect to the accelerator device; and determining a next checkpoint according to a checkpoint adjustment strategy that determines the next checkpoint based on the API execution logic and based on the current API execution cycle of the application, wherein the checkpoint adjustment strategy corresponds to at least one API execution logic among plural API execution logics.
