    摘要: A method and apparatus for reducing the effect of soft errors in a computer system is provided. Soft errors are detected by combining software redundant threading and instruction duplication. Upon detection of a soft error, errors are recovered through the use of software check pointing/rollback technology. Reliable regions are identified by vulnerability profiling and redundant multi-threading is applied to the identified reliable regions.
