    摘要： In a computer system supporting memory compression, wherein memory compressed data is managed in units of memory sectors of size S, wherein data is stored on disk in a different compressed format, and wherein data on said disk is managed in units of disk sectors of size D, a method for storing memory compressed data on a compressed disk includes combining at least one of compressed memory directory information, a system header, compressed data controls, and pads into a data structure having a same size S as a memory sector, grouping the data structure and the data contained in the desired memory sectors into groups of D/S items, and storing each of the groups in a separate disk sector.

    摘要： A computing system and method employing a processor device for generating real addresses associated with memory locations of a real memory system for reading and writing of data thereto, the system comprising: a plurality of memory blocks in the real memory system for storing data, a physical memory storage for storing the pages of data comprising one or more real memory blocks, each real memory block partitioned into one or more sectors, each comprising contiguous bytes of physical memory; a translation table structure in the physical memory storage having entries for associating a real address with sectors of the physical memory, each translation table entry including one or more pointers for pointing to a corresponding sector in its associated real memory block, the table accessed for storing data in one or more allocated sectors for memory read and write operations initiated by the processor; and, a control device for directly manipulating entries in the translation table structure for performing page operations without actually accessing physical memory data contents. In this system, the actual data of the pages involved in the operation are never accessed by the processor and therefore is never required in the memory cache hierarchy, thus eliminating the cache damage normally associated with these block operations. Further the manipulation of the translation table will involve reading and writing a few bytes to perform the operation as opposed to reading and writing the hundreds or thousands of bytes in the pages being manipulated.

    摘要： Systems and methods are provided that schedule task requests within a computing system based upon the history of task requests. The history of task requests can be represented by a historical log that monitors the receipt of high priority task request submissions over time. This historical log in combination with other user defined scheduling rules is used to schedule the task requests. Task requests in the computer system are maintained in a list that can be divided into a hierarchy of queues differentiated by the level of priority associated with the task requests contained within that queue. The user-defined scheduling rules give scheduling priority to the higher priority task requests, and the historical log is used to predict subsequent submissions of high priority task requests so that lower priority task requests that would interfere with the higher priority task requests will be delayed or will not be scheduled for processing.

    摘要： In a computer system supporting memory compression and wherein data is stored on a disk in a different compressed format, and wherein an IOA (input/output adaptor)/IOP (input/output processor) selectively reads from and writes to a main memory through a direct memory access (DMA) operation, a method for transmitting compressed data from the IOA/IOP to the main memory includes reserving a set of free memory sectors to contain the data in said main memory, sending to the IOA/IOP addresses of said memory sectors, copying the data from the IOA/IOP to said memory sectors using said DMA operation, constructing at the IOA/IOP compressed memory directory information defining how and where the data is stored in memory, sending the memory directory information to a memory controller, and storing the memory directory information in the compressed memory directory structure.

    摘要： We present a “directory extension” (hereinafter “DX”) to aid in prefetching between proximate levels in a cache hierarchy. The DX may maintain (1) a list of pages which contains recently ejected lines from a given level in the cache hierarchy, and (2) for each page in this list, the identity of a set of ejected lines, provided these lines are prefetchable from, for example, the next level of the cache hierarchy. Given a cache fault to a line within a page in this list, other lines from this page may then be prefetched without the substantial overhead to directory lookup which would otherwise be required.
