    摘要: A buffer cache interposed between a non-volatile memory and a host may be partitioned into segments that may operate with different policies. Cache policies include write-through, wire and read-look-ahead. Write-through and write back policies may improve speed. Read-look-ahead cache allows more efficient use of the bus between the buffer cache and non-volatile memory. A session command allows data to be maintained in volatile memory by guaranteeing against power loss.

    摘要: Embodiments of the present invention provide a memory resource optimization method and apparatus, relate to the computer field, solve a problem that existing multi-level memory resources affect each other, and optimize an existing single partitioning mechanism. A specific solution is: obtaining performance data of each program in a working set by using a page coloring technology, obtaining a category of each program in light of a memory access frequency, selecting, according to the category of each program, a page coloring-based partitioning policy corresponding to the working set, and writing the page coloring-based partitioning policy to an operating system kernel, to complete corresponding coloring-based partitioning processing. The present invention is used to eliminate or reduce mutual interference of processes or threads on a storage resource in light of a feature of the working set, thereby improving overall performance of a computer.

    摘要: The present invention extends to methods, systems, and computer program products for implementing a cache using multiple page replacement algorithms. An exemplary cache can include two logical portions where the first portion implements the least recently used (LRU) algorithm and the second portion implements the least recently used two (LRU2) algorithm to perform page replacement within the respective portion. By implementing multiple algorithms, a more efficient cache can be implemented where the pages most likely to be accessed again are retained in the cache. Multiple page replacement algorithms can be used in any cache including an operating system cache for caching pages accessed via buffered I/O, as well as a cache for caching pages accessed via unbuffered I/O such as accesses to virtual disks made by virtual machines.
