A distributed cache system in distributed information access environment is discussed in this paper, which is used to increase the access efficiency and reduce the communication throughout. The cache node can store the data from multiple data sources. Different access of information can reuse the same cached data and thus improve the hit rates. The cache system adopts various methods to keep the consistency of cached data. Finally, concept of virtual cache node is proposed, which extends the original caching...

A distributed cache system in distributed information access environment is discussed in this paper, which is used to increase the access efficiency and reduce the communication throughout. The cache node can store the data from multiple data sources. Different access of information can reuse the same cached data and thus improve the hit rates. The cache system adopts various methods to keep the consistency of cached data. Finally, concept of virtual cache node is proposed, which extends the original caching system. The adoption of virtual nodes is for reducing the amount of replicated cached data and reduce the computation cost for a global optimized accessing plan computation.

CME (cache miss equations) is a kind of math framework which can accurately analyse the cache hit rate of the loops in program.
