Abstract
Method, system, and computer program product for saving and restarting discrete event simulations are provided. A discrete event simulation of a scenario is performed via a process executing on a system. The process includes one or more application threads. A checkpoint of the process is created at a point in time when a command to save the discrete event simulation of the scenario is received. The checkpoint includes data elements of the process and the one or more application threads of the process that are stored in components of the system at the point in time. These data elements reflect a state of the process and the one or more application threads of the process at the point in time. The checkpoint is saved to one or more files in the system that are usable to later restart the discrete event simulation of the scenario from the point in time.
