Abstract
This disclosure provides apparatus, methods and systems for error correction in multi processor systems. Some implementations include a plurality of computing modules, each computing module including a processor. Each processor may include processing state. In some other implementations, each computing module may also include a memory. Upon receiving a signal to perform a partial re-synchronization, a hash of each processor's state data may be performed. In some embodiments, a hash of at least a portion of each computing module's memory data may also be performed. The hashes for each processor are then compared to determine majority hashes and possible minority hashes. Upon identifying a minority hash, the computing module that produced the minority hash may receive new processing state data from one of the computing modules that produced a majority hash.
