Some versions of a cache line demote instruction receive an address (e.g., 64 byte aligned) as an input and an uncore (or system agent) registers this address and opportunistically demotes content of the cache line associated with the address to a last level cache that is accessible by mul...
Cache partitioning is a technique to reduce interference among tasks running on the processors with shared caches. To make this technique effective, cache
Cache-Aligned Data Buffers Context: Your application/driver caches packet buffers and buffer descriptors. Problem: You need to use the cache as effectively as possible. On some systems, the descriptors might be larger than a cache line. Solution: Allocate key data on cache line boundaries. This...
