Abstract
In one embodiment, the present invention includes a method for receiving a request for data in a home agent of a system from a first agent, prefetching the data from a memory and accessing a directory entry to determine whether a copy of the data is cached in any system agent, and forwarding the data to the first agent without waiting for snoop responses from other system agents if the directory entry indicates that the data is not cached. Other embodiments are described and claimed.
