Abstract
A system, method, and computer program product are provided for conditionally sending a request for data to a home node. In operation, a first request for data is sent to a first cache of a node. Additionally, if the data does not exist in the first cache, a second request for the data is sent to a second cache of the node. Furthermore, a third request for the data is conditionally sent to a home node.
Claims20
A method of querying a plurality of nodes for data requested by a processor, comprising:
- determining that the requested data does not exist in a first cache;
- determining that the requested data does not exist in a second cache;
- sending a request for the requested data to a node determined to be a home node for a particular memory address associated with the requested data.
A system capable of querying a plurality of nodes for requested data, comprising,
- a home node associated with a particular memory address associated with the requested data;
- and
- a processor configured to:
- determine that the requested data does not exist in a first cache;
- determine that the requested data does not exist in a second cache;
- send a request for the requested data to the home node.
