System and method for providing a fault tolerant computer program runtime support environment

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