Apparatus, method, and system for enhanced data prefetching based on non-uniform memory access (numa) characteristics

A method implemented in a computer processor, the method comprising:

• storing data in a system memory, wherein the system memory comprises a plurality of memory regions, each of the plurality of memory regions is associated with a respective set of prefetch parameters, at least one of the plurality of memory regions having a prefetch parameter value that is different than a corresponding prefetch parameter value of another one of the plurality of memory regions;
• monitoring data accesses to a cache;
• and
• generating one or more prefetch requests to fetch data from the system memory to the cache, wherein the one or more prefetch requests are generated based on the monitored data accesses to the cache and the set of prefetch parameters associated with the memory region from which data is to be fetched.

A system comprising:

• one or more processor cores;
• a system memory to store data, the system memory comprising a plurality of memory regions each of the plurality of memory regions is associated with a respective set of prefetch parameters, at least one of the plurality of memory regions having a prefetch parameter value that is different than a corresponding prefetch parameter value of another one of the plurality of memory regions;
• a cache to store data received from the system memory, the cache shared by the one or more processor cores;
• and
• a prefetcher to monitor data accesses from the one or more processor cores to the cache and to generate one or more prefetch requests to fetch data from the system memory to the cache, wherein the one or more prefetch requests are generated based on the monitored data accesses and the set of prefetch parameters associated with the memory region from which data is to be fetched.
