cache consistency meaning

• [Computer]
  <storage> (Or "cache consistency") /kash koh-heer'n-see/ The synchronisation of data in multiple caches such that reading a memory location via any cache will return the most recent data written to that location via any (other) cache.
  
  Some parallel processors do not cache accesses to shared memory to avoid the issue of cache coherency. If caches are used with shared memory then some system is required to detect when data in one processor's cache should be discarded or replaced because another processor has updated that memory location. Several such schemes have been devised.

• Slow consistency is a weaker model than PRAM and cache consistency.
• Cache consistency is weaker than process consistency and incomparable with PRAM consistency.
• Cache consistency requires that all write operations to the same memory location are performed in some sequential order.
• The fact that the only writes seen in order are writes to the same memory location limits this example to Cache Consistency.
• Processor Consistency is also stronger than Cache Consistency because Processor Consistency requires all writes by a processor to be seen in order, not just writes to the same memory location.
• The second-generation i860 "'XP "'microprocessor ( code named "'N11 "') added 4 Mbyte pages, larger on-chip caches, second level cache support, faster buses, and hardware support for bus snooping, for cache consistency in multiprocessor systems.
