One embodiment of the present invention provides a system for recovering a process that is multi-threaded from checkpoint information that was previously stored for the process. During a recovery operation, the system first retrieves the checkpoint information for the process. Next, the system extracts an identifier for a program being run by the process as well as parameters of the program from the checkpoint information. The system also extracts thread identifiers for threads associated with the process from the checkpoint information. Next, the system modifies the program so that executing the program will cause threads associated with the process to be restored. The system then creates a replacement process to replace the process, and causes the replacement process to execute the modified program so that the threads are reconstituted within the replacement process.
