摘要： A system and method for a distributed directory cache in a computing system. A system comprises a plurality of nodes including at least a source node, home node, and one or more target nodes. The source node is configured to convey a request to a home node for a coherency unit, wherein the coherency unit corresponds to a super line which comprises a plurality of coherency units including the requested coherency unit. Prior to conveying the request, the source node is configured to indicate that the request is a non-probing request responsive to determining that none of the plurality of coherency units of the super line are cached in any of the other nodes. In response to receiving the request, the home node is configured to initiate the conveyance of one or more probes to one or more target nodes, if the response does not indicate it is a non-probing request, and inhibit the conveyance of the probes if the request indicates it is a non-probing request.
