摘要： In a system with hardware main memory compression, the method of this invention monitors the physical memory utilization and if physical memory is near exhaustion it forces memory to be paged out, thus freeing up real memory pages. These pages are then zeroed, thus they are highly compressible and therefore reduce the physical memory utilization. Pages that have been forced out due to high physical memory utilization are not made available for allocation. In systems where operating system changes are permitted, this invention dynamically controls the minimum size of the free page pool and zeros pages upon freeing. When the physical memory utilization falls below a critical threshold the mechanism reduces the minimum size of the free pool to allow further allocation. In systems where operating system changes are not possible, pages are allocated by a module (e.g. Device driver) and then zeroed. When the physical memory utilization falls below a critical threshold this method frees some of the explicitly set aside pages.
摘要翻译：在具有硬件主存储器压缩的系统中，本发明的方法监视物理存储器利用率，并且如果物理存储器接近耗尽，则迫使存储器被分页出来，从而释放真实存储器页面。这些页面然后归零，因此它们是高度可压缩的，因此减少物理内存利用率。由于物理内存利用率高而被强制退出的页面不可用于分配。在允许操作系统更改的系统中，本发明在释放时动态地控制自由页面池和零页面的最小尺寸。当物理内存利用率低于临界阈值时，机制会降低可用池的最小大小以允许进一步分配。在不可能进行操作系统更改的系统中，页面由模块（例如，设备驱动程序）分配，然后归零。当物理内存利用率低于临界阈值时，此方法会释放某些明确设置的页面。

摘要： A computer system includes N multi-threaded processors and an operating system. The N multi-threaded processors each have O hardware threads forming a pool of P hardware threads, where N, O, and P are positive integers and P is equal to N times O. The operating system includes a scheduler which receives events for one or more computing jobs. The scheduler receives one of the events and allocates R hardware threads of the pool of P hardware threads to one of the computing jobs by optimizing a sum of priorities of the computing jobs, where each priority is based in part on the number of logical processors requested by a corresponding computing job and R is an integer that is greater than or equal to 0.

摘要： A system and method for managing a memory storage device including a physical memory having free space for storing content maintained in compressed form and organized as pages. The system includes a control device for managing performance of input and output operations of compressed content to and from the memory storage device, with output operations including a memory pageout operations for recovering free memory storage space. The control device maintains an amount of free storage space readily available for recovery to above a threshold amount so as to enable subsequent pageout operations to be performed. A novel data construct is provided that includes locations of pages which may be immediately cleared from the physical memory for a subsequent pageout operation, the control device performing a flush operation by accessing the data construct and expediently deleting one or more pages identified in the list as available for deletion. With this data construct and flush operation, the threshold amount for free storage space recovery is able to be significantly reduced.

摘要： An improved method, system, and a computer program storage device for management of compressed main memory allocation and utilization. The present invention has features which advantageously avoid system abends or inefficient operation that would otherwise result. We identify 3 types of addresses associated with a page: a virtual address, a real address, and a physical address. The OS is responsible for converting virtual addresses to real addresses, and the memory controller is responsible for converting real addresses to the physical addresses where the compressed data are actually stored. We assume that the memory controller has the capability to store a page either compressed, or uncompressed. Depending on the characteristics of the controller, this may be done either on a per page basis via an indicator bit that is settable by the OS, or on a range of real addresses.

摘要： The present invention describes lossless data compression/decompression methods and systems. A random access memory (RAM) operates as a static dictionary and includes commonly used strings/symbols/phrases/words. An input buffer operates as a dynamic dictionary and includes input strings/phrases/symbols/words. A set-associative cache memory operates as a hash table, and includes pointers pointing to the commonly used strings/symbols/phrases/words in the static dictionary and/or pointing to one or more of the input strings/phrases/symbols/words in the dynamic dictionary. Alternatively, the set-associative cache memory combines the dynamic dictionary, the static dictionary and the hash table. When encountering a symbol/phrase/string/word in the static or dynamic dictionary in an input stream, a compressor logic or module places a pointer pointing to the symbol/phrase/string/word at a current location on the output stream. The hash table may include phrases/symbols/strings/words and/or pointers pointing to phrases/symbols/strings/words.
