摘要： A cache module (26) at a client computer (12) controls a cache portion (28) on a storage device (24). The cache module communicates with other cache modules at other clients to form a cache community (15). The cache modules store World Wide Web or other content in the cache portions for retrieval in response to requests (32) for content from browsers (30) in the cache community. When the requested content is not available in the cache community, the requested content may be retrieved from an origin server (19) using the Internet.

摘要： A system and method for automatically migrating the execution of work units between multiple heterogeneous cores. A computing system includes a first processor core with a single instruction multiple data micro-architecture and a second processor core with a general-purpose micro-architecture. A compiler predicts execution of a function call in a program migrates at a given location to a different processor core. The compiler creates a data structure to support moving live values associated with the execution of the function call at the given location. An operating system (OS) scheduler schedules at least code before the given location in program order to the first processor core. In response to receiving an indication that a condition for migration is satisfied, the OS scheduler moves the live values to a location indicated by the data structure for access by the second processor core and schedules code after the given location to the second processor core.

摘要： A system and method for automatically optimizing parallel execution of multiple work units in a processor by reducing a number of branch instructions. A computing system includes a first processor core with a general-purpose micro-architecture and a second processor core with a same instruction multiple data (SIMD) micro-architecture. A compiler detects and evaluates branches within function calls with one or more records of data used to determine one or more outcomes. Multiple compute sub-kernels are generated, each comprising code from the function corresponding to a unique outcome of the branch. Multiple work units are produced by assigning one or more records of data corresponding to a given outcome of the branch to one of the multiple compute sub-kernels associated with the given outcome. The branch is removed. An operating system scheduler schedules each of the one or more compute sub-kernels to the first processor core or to the second processor core.

摘要： A system and method for allocating memory to multi-threaded programs on a Non-Uniform Memory Access (NUMA) computer system using a NUMA-aware memory heap manager is disclosed. In embodiments, a NUMA-aware memory heap manager may attempt to maximize the locality of memory allocations in a NUMA system by allocating memory blocks that are near, or on the same node, as the thread that requested the memory allocation. A heap manager may keep track of each memory block's location and satisfy allocation requests by determining an allocation node dependent, at least in part, on its locality to that of the requesting thread. When possible, a heap manger may attempt to allocate memory on the same node as the requesting thread. The heap manager may be non-application-specific, may employ multiple levels of free block caching, and/or may employ various listings that associate given memory blocks with each NUMA node.
