摘要: A performance enhancing change-to-dirty operation (CTD) is disclosed wherein contention among several processors trying to gain ownership of a block data obviated by arranging the CTD always succeed. method and system are where processor in multiprocessor having copy gains assured that may then write. The provides for possibilities conditions exist scenario requesting have wait ownership. Conditions handled memory “owner” other ownership, copies at processors. messages informing them now invalid.
