Abstract

The use of out-of-order execution and branch predictions in the design of supercomputers to increase performance means there must be some kind of repair mechanism, since situations do occur that require the computing engine to repair to a known previous state. One way to handle this is by checkpoint repair. Several properties of checkpoint repair mechanisms are derived, and algorithms for performing checkpoint repair that incur very little overhead in time and modest cost in hardware are provided. The algorithms require no additional complexity or time for use with write-back cache memory systems than they do with write-through cache memory systems.
