{{further|Fault-tolerant computer system}}
Parallel computing can also be applied to the design of [[fault-tolerant computer system]]s, particularly via [[Lockstep (computing)|lockstep]] systems performing the same operation in parallel. This provides [[Redundancy (engineering)|redundancy]] in case one component fails, and also allows automatic [[error detection]] and [[error correction]] if the results differ. These methods can be used to help prevent single-event upsets caused by transient errors.<ref>Dobel, B., Hartig, H., & Engel, M. (2012) "Operating system support for redundant multithreading". ''Proceedings of the Tenth ACM International Conference on Embedded Software'', 83–92. {{doi|10.1145/2380356.2380375}}</ref> Although additional measures may be required in embedded or specialized systems, this method can provide a cost-effective approach to achieve n-modular redundancy in commercial off-the-shelf systems.
