Monitoring cache usage in a distributed shared cache

A method, comprising:

• receiving a request for a cache line occupancy count of a process identification (ID) in a cache memory, wherein the cache memory comprises a total number of sets, each set including a plurality of cache lines;
• reading a cache line occupancy count value at the process ID location in at least one process resource table associated with the cache memory, wherein the at least one process resource table stores the occupancy count of cache lines for a subset of less than the total number of cache lines in the cache memory.

The system of claim 20, wherein the multi-core processor is further operable to:

• update the at least one process resource table when the processor core swaps a utilization of a cache line of the plurality of cache lines from a first process to a second process.

The system of claim 20, further comprising:

• an interval timer,
• wherein the multi-core processor is further operable to update the at least one process resource table with current cache line occupancy counts when the interval timer expires.
