The National Interagency Support Cache System is made up of 15 caches in strategic locations throughout the United States. Ft. Wainwright, AK; Boise, ID; Missoula, MT; Redmond, OR; Redding, CA; Ontario, CA; Denver, CO; Prescott, AZ; Silver City, NM; London, KY; Grand Rapids, MN; LaGrande, OR; Wenatchee, WA; Billings, MT & Coeur d’ Alene, ID. The caches are operated under the direction of federal and state agencies, including the US Forest Service; Bureau of Land Management and various states including Alaska, Minnesota and Idaho..

Cache hit rate = (# hits) / (# hits # misses) = (# hits) / (# accesses). Virtual Memory Use main memory as a “cache” for secondary (disk) storage Managed jointly by CPU hardware and the operating system (OS) Programs share main memory Each gets a private virtual address space holding its frequently used code and data
