ABSTRACT:
A system and method for automatically checkpointing a primary computer process to a backup computer process is disclosed. The system and method automatically convert a non-fault tolerant computer program into a fault tolerant computer program. The system includes multiple CPUs, a communications link between the CPUs and a user interface device, such as a terminal, workstation, or PC. A special layer of code forms an interface between the operating system for each CPU and the application programs running on the CPUs. For each process, running on one of the CPUs, the interface automatically creates a duplicate backup process on another CPU. The interface handles synchronizing communications between the original or primary process and the backup process, and suppresses or otherwise prevents or inhibits output from the backup process.
