摘要
A first processing element is configured to execute a first thread and one or more second processing elements are configured to execute one or more second threads that are redundant to the first thread. The first thread and the one or more second threads are to selectively bypass one or more comparisons of results of operations performed by the first thread and the one or more second threads depending on whether an event trigger for the comparison has occurred a configurable number of times since a previous comparison of previously encoded values of the results. In some cases the comparison can be performed based on hashed (or encoded) values of the results of a current operation and one or more previous operations.
