Delayed Precise Invalidation - A Software Cache Coherence Scheme

: Software cache coherence schemes are very desirable in the design of scalable multiprocessors and massively parallel processors. The authors propose a software cache coherence scheme named `delayed precise invalidation' (DPI). DPI is based on compiler-time markings of references and a hardware local invalidation of stale data in parallel and selectively. With a small amount of additional hardware and a small set of cache management instructions, this scheme provides more cacheability and allows invalidation of partial elements in an array, overcoming some inefficienciesand deficiencies of previous software cache coherence schemes.
