The flash memory is being used to an everincreasing extent in consumer electronics for the purpose of the dominant secondary storage device. Aiming at the buffer replacement policy for flash-based storage devices in efficiency, a new efficient flash-aware buffer replacement algorithm based on probability is proposed, where three LRU linked lists are used to(More)
Map Reduce has emerged as a popular computing model for parallel processing of cloud computing. Map Reduce performance analysis and modeling is needed to guide performance optimization and job scheduling. However, we observed that it is difficult to build a performance model due to various aspects of workload behavior and heterogeneity among cluster nodes(More)
