Abstract: A spin counter updating system and method for updating spin counters for spi n latches in a multiprocessor computing system. The updating system includes main spin counter value storage for storing spin counter data correlated to at least one spin counter value, and a master agent. The master agent includes agent spin counter value storage for storing spin counter data correlated to at least one spin counter value; and a spin counter signal handler, wherein the spin counter signal handler is adapted to read spin counter data from the main spin counter valu e storage and to store the read spin counter data to the agent spin counter value storage.
