摘要： A system provides efficient dispatch/completion of an N Dimensional (ND) Range command in a data processing system (DPS). The system comprises: a compiler generating one or more commands from received program instructions; ND Range work processing (WP) logic determining when a command generated by the compiler will be implemented over an ND configuration of operands, where N is greater than one (1); automatically decomposing the ND configuration of operands into a one (1) dimension (1D) work element comprising P sequentially ordered work items that each represent one of the operands; placing the 1D work element within a command queue of the DPS; enabling sequential dispatching of 1D work items in ordered sequence from to one or more processing units; and generating an ND Range output by mapping the 1D work output result to an ND position corresponding to an original location of the operand represented by the 1D work item.

摘要： A mechanism is provided for security screening image analysis simplification through object pattern identification. Popular consumer electronics and other items are scanned in a control system, which creates an electronic signature for each known object. The system may reduce the signature to a hash value and place each signature for each known object in a “known good” storage set. For example, popular mobile phones, laptop computers, digital cameras, and the like may be scanned for the known good signature database. At the time of scan, such as at an airport, objects in a bag may be rotated to a common axis alignment and transformed to the same signature or hash value to match against the known good signature database. If an item matches, the scanning system marks it as a known safe object.

摘要： A method for efficient dispatch/completion of a work element within a multi-node data processing system. The method comprises: selecting specific processing units from among the processing nodes to complete execution of a work element that has multiple individual work items that may be independently executed by different ones of the processing units; generating an allocated processor unit (APU) bit mask that identifies at least one of the processing units that has been selected; placing the work element in a first entry of a global command queue (GCQ); associating the APU mask with the work element in the GCQ; and responsive to receipt at the GCQ of work requests from each of the multiple processing nodes or the processing units, enabling only the selected specific ones of the processing nodes or the processing units to be able to retrieve work from the work element in the GCQ.

摘要： A method for managing hardware resources and threads within a data processing system is disclosed. Compilation attributes of a function are collected during and after the compilation of the function. The pre-processing attributes of the function are also collected before the execution of the function. The collected attributes of the function are then analyzed, and a runtime configuration is assigned to the function based of the result of the attribute analysis. The runtime configuration may include, for example, the designation of the function to be executed under either a single-threaded mode or a simultaneous multi-threaded mode. During the execution of the function, real-time attributes of the function are being continuously collected. If necessary, the runtime configuration under which the function is being executed can be changed based on the real-time attributes collected during the execution of the function.

摘要： Scene model data, including a scene geometry model and a plurality of pixel data describing objects arranged in a scene, is received. A primary pixel color and a primary ray are generated based on a selected first pixel data. If the primary ray intersects an object in the scene, an intersection point is determined. A surface normal is determined based on the object intersected and the intersection point. The primary pixel color is modified based on a primary hit color, determined based on the intersection point. A plurality of ambient occlusion (AO) rays each having a direction, D, are generated based on the intersection point, P and the surface normal. Each AO ray direction is reversed and the AO ray origin is set to a point outside the scene. An AO ray that does not intersect an object before reaching the intersection point is included in ambient occlusion calculations. The primary pixel color is shaded based on the ambient occlusion and the primary hit color and an image is generated based on the primary pixel color for the pixel data.

摘要： Disclosed are a method, a system and a computer program product of operating a data processing system that can include or be coupled to multiple processor cores. In one or more embodiments, each of multiple memory objects can be populated with work items and can be associated with attributes that can include information which can be used to describe data of each memory object and/or which can be used to process data of each memory object. The attributes can be used to indicate one or more of a cache policy, a cache size, and a cache line size, among others. In one or more embodiments, the attributes can be used as a history of how each memory object is used. The attributes can be used to indicate cache history statistics (e.g., a hit rate, a miss rate, etc.).
