Transparent Recovery from Operating System Errors

Errors that occur in operating systems usually impact all user applications and may render a computer unusable. This is unfortunately the case even when the error only affects an operating system component that is not crucial to the functioning of most applications. CuriOS is a new operating system that uses lightweight distribution, isolation and persistence of state to transparently recover from errors and continue running existing applications. Errors are detected through techniques such as virtual memory protection, watchdog timers and checksums. Errors are fixed by restarting OS components without any loss of state.
