Technologies for region-biased cache management

One or more non-transitory, computer-readable storage media comprising a plurality of instructions stored thereon that in response to being executed cause a network computing device to:

• select a cache line of a cache memory for eviction, wherein the cache line is one of a plurality of cache lines of the cache memory of the network computing device;
• determine whether the cache line selected for eviction resides in a cache block of the cache memory that is presently mapped to a corresponding memory region of a main memory of the network computing device, wherein the cache block comprises one or more of the plurality of cache lines;
• retrieve, in response to a determination that the cache block is mapped to a corresponding memory region, a bias value associated with the corresponding memory region, wherein the bias value corresponds to a fractional probability;
• generate a bias comparator value for the corresponding memory region;
• compare the bias value of the corresponding memory region and the bias comparator value generated for the corresponding memory region;
• and
• evict the cache line in response to a determination that a result of the comparison indicates to evict the cache line.

A method for region-based cache management, the method comprising:

• selecting, by a network computing device, a cache line for eviction from the plurality of cache lines, wherein the cache line comprises one of a plurality of cache lines of a cache memory residing on a processor of the network computing device;
• determining, by the network computing device, whether the cache line selected for eviction resides in a cache block of the cache memory that is presently mapped to a corresponding memory region of a main memory of the network computing device externally coupled to the processor, wherein the cache block comprises one or more of the plurality of cache lines;
• retrieving, by the network computing device and in response to a determination that the cache block is mapped to a corresponding memory region, a bias value associated with the corresponding memory region, wherein the bias value corresponds to a fractional probability;
• generating, by the network computing device, a bias comparator value for the corresponding memory region;
• comparing, by the network computing device, the bias value of the corresponding memory region and the bias comparator value generated for the corresponding memory region;
• and
• evicting, by the network computing device, the cache line in response to a determination that a result of the comparison indicates to evict the cache line.

A network computing device for region-based cache management, the network computing device comprising:

• a cache memory management circuit to select a cache line for eviction from the plurality of cache lines, wherein the cache line comprises one of a plurality of cache lines of a cache memory residing on a processor of the network computing device;
• means for determining whether the cache line selected for eviction resides in a cache block of the cache memory that is presently mapped to a corresponding memory region of a main memory of the network computing device coupled to the processor, wherein the cache block comprises one or more of the plurality of cache lines;
• means for retrieving, in response to a determination that the cache block is mapped to a corresponding memory region, a bias value associated with the corresponding memory region, wherein the bias value corresponds to a fractional probability;
• means for generating a bias comparator value for the corresponding memory region;
• and
• means for comparing the bias value of the corresponding memory region and the bias comparator value generated for the corresponding memory region,
• wherein the cache memory management circuit is further to evict the cache line in response to a determination that a result of the comparison indicates to evict the cache line.
