Failure-oblivious computing is a technique that enables computer programs to continue executing despite memory errors. The technique handles attempts to read invalid memory by returning a manufactured value to the program, and it ignores invalid writes. This is a great contrast to typical memory checkers, which inform the program of the error or abort the program. In failure-oblivious computing, no attempt is made to inform the program that an error occurred.[1]
The approach has performance costs: because the technique rewrites code to insert dynamic checks for address validity, execution time will increase by 80% to 500%.[2]
