cache consistency การใช้

• 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.
