Resolving conflicts in a transactional execution model of a multiprocessor system

摘要

In one embodiment, the present invention includes a method for resolving conflicts, including receiving data access requests from multiple requestors at a home agent that owns the data, determining whether any of the requests are transactional requests, any of the requestors obtains the data forwarded from another agent, and a highest priority transactional requestor, and based at least in part on the determining, sending from the home agent a first message to the highest priority transactional requestor to indicate that the highest priority transactional requestor is to not abort its transaction and a second message to the other requestor to indicate that the corresponding requestor is to abort its transaction. Other embodiments are described and claimed.
