Abstract:

A computer implemented method, apparatus, and computer program product for checkpoint and restart of a process. In one embodiment, a process shell representing a restartable process is created on an arrival server in response to identifying a process on a departure server that is a restartable process. The process shell is frozen. A name of the restartable process, an identifier of the restartable process, and an identifier of a parent process of the restartable process is assigned to the process shell. The process shell is then unfrozen and exits. A parent process restarts the restartable process when the process shell exits.
