checkpoint |
2 definitions found From WordNet r 1.6 [wn]: checkpoint n : a place (as at a frontier) where travellers are stopped for inspection and clearance From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: checkpoint Saving the current state of a program and its data, including intermediate results to disk or other {non-volatile storage}, so that if interrupted the program could be restarted at the point at which the last checkpoint occurred. This facility came into popular use in {mainframe} {operating systems}s such as {OS/360} in which programs frequently ran for longer than the mean time between system failures. If a program run fails because of some event beyond the program's control (e.g. hardware or {operating system} failure) then the processor time invested before the checkpoint will not have been wasted.
