Abstract
A multiprocessor computing apparatus that includes a mechanism for favoring at least one processor over another processor to achieve more equitable access to cached data. Logic for detecting when, for example, a remote and a local processor are attempting to access data from the cache of another local processor is disclosed. Logic that provides an advantage to the remote processor in a manner that achieves fairer access among the various processors is also disclosed.
