computer engineering, directory-based cache coherence is a type of cache coherence mechanism, where directories are used to manage caches in place of bus snooping...

mismatched. A cache coherence protocol is used to maintain cache coherency. The two main types are snooping and directory-based protocols. Cache coherence is of...

achieved through a distributed directory-based cache coherence model. (The other popular models for cache coherency are based on system-wide eavesdropping...

Directory-based coherence is a mechanism to handle cache coherence problem in distributed shared memory (DSM) a.k.a. non-uniform memory access (NUMA)....

Routing Chip. The boards designed at Stanford implemented a directory-based cache coherence protocol allowing Stanford DASH to support distributed shared...

directory-based or snooping-based (also called sniffing). Specific protocols include the MSI protocol and its derivatives MESI, MOSI and MOESI. Cache...

aspect. It combines both snoopy cache and point-to-point directory-based models to give a two-level cache coherence model. Snoopy buses are used primarily...

schemes can be classified based on: Snoopy scheme vs Directory scheme and vs Shared caches Write through vs Write-back (ownership-based) protocol Update vs...

coherence mechanisms are typically used to implement the migration. A huge body of research has explored these issues. Various forms of directories,...

Hardware examples include cache coherence circuits and network interface controllers. There are three ways of implementing DSM: Page-based approach using virtual...

non-shared memory known as cache to exploit locality of reference in memory accesses. With NUMA, maintaining cache coherence across shared memory has a...

larger cache coherent NUMA (ccNUMA) systems tend to use directory-based coherence protocols. When a bus transaction occurs to a specific cache block,...

computing, the MSI protocol - a basic cache-coherence protocol - operates in multiprocessor systems. As with other cache coherency protocols, the letters of...
