SYSTEM, METHOD AND DEVICE FOR ERROR CORRECTION IN MULTIPROCESSOR SYSTEMS Russian patent published in 2016 - IPC G06F11/00 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. The method comprises: saving a portion of processor state data for each of a plurality of computing modules; hashing a portion of the saved processor state data for each of the plurality of computing modules; comparing the processor hashes for the processor state data; determining a majority of computing modules having the same processor state data and at least one minority of computing modules having different processor state data; re-synchronising the plurality of computing modules; sending the saved processor state data from a first majority computing module to a first minority computing module; confirming that the state data of a second majority computing module is the same as the saved state data from the first majority computing module or the saved state data of the first minority computing module after sending the saved processor state data from the first majority computing module to the minority computing module; flagging an error if the state data is not the same.

EFFECT: improved computer system security.
