HiPEC: high performance external virtual memory caching

摘要: Traditional operating systems use a fixed LRU-like page replacement policy and centralized frame pool that cannot properly serve all types of memory access patterns various applications As result many memory-intensive such as databases multimedia scientific simulators induce excessive faults when running on top existing systems.This paper presents High Performance External virtual Caching mechanism (HiPEC) to provide with their own specific management. The user programmed in the HiPEC command set is stored address space. When fault occurs kernel fetches interprets corresponding commands perform Experimental results show induces little overhead can significantly improve performance for applications.
