Abstract
A system for conditional memory ordering implemented in a multiprocessor environment. A conditional memory ordering instruction executes locally using a release vector containing release numbers for each processor in the system. The instruction first determines whether a processor identifier of the release number is associated with the current processor. Where it is not, a conditional registered is examined and appropriate remote synchronization operations are commanded where necessary.
