System and method for managing cache access in a distributed system

A method comprising:

• receiving at a local processing unit a request for data from a remote processing unit;
• determining whether the requested data resides within a cache memory associated with a cache memory associated with the local processing unit;
• and
• reading the requested data from the cache memory and communicating it to the remote processing unit, if the requested data is determined to reside in the cache memory.

A method comprising:

• receiving at a local processing unit a request for data from a remote processing unit;
• retrieving the requested data from a system memory;
• determining whether the requested data is likely to be requested again in a short time period;
• and
• writing the requested data into a cache memory associated with the local processing unit, if it is determined that the requested data is likely to be requested again in a relatively short time period.

A method comprising:

• generating a work queue by a producer unit;
• storing the work queue in a cache memory associated with the producer functional unit;
• receiving a request or information of the work queue by a consumer functional unit;
• retrieving the requested information from the cache memory and communicating the retrieved information to the consumer functional unit;
• and
• invalidating the retrieved information within the cache memory without writing or synchronizing the retrieved information with a system memory.
