摘要： A technique 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： A mechanism is provided in a multi-core environment for assigning a globally unique core identifier. A Power PC® processor unit (PPU) determines an index alias corresponding to a natural index to a location in local storage (LS) memory. A synergistic processor unit (SPU) corresponding to the PPU translates the natural index to a first address in a core's memory, as well as translates the index alias to a second address in the core's memory. Responsive to the second address exceeding a physical memory size, the load store unit of the SPU truncates the second address to a usable range of address space in systems that do not map an address space. The second address and the first address point to the same physical location in the core's memory. In addition, the aliasing using index aliases also preserves the ability to combine persistent indices with relative indices without creating holes in a relative index map.

摘要： A method provides efficient dispatch/completion of an N Dimensional (ND) Range command in a data processing system (DPS). The method 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 method efficiently dispatches/completes a work element within a multi-node, data processing system that has a global command queue (GCQ) and at least one high latency node. The method comprises: at the high latency processor node, work scheduling logic establishing a local command/work queue (LCQ) in which multiple work items for execution by local processing units can be staged prior to execution; a first local processing unit retrieving via a work request a larger chunk size of work than can be completed in a normal work completion/execution cycle by the local processing unit; storing the larger chunk size of work retrieved in a local command/work queue (LCQ); enabling the first local processing unit to locally schedule and complete portions of the work stored within the LCQ; and transmitting a next work request to the GCQ only when all the work within the LCQ has been dispatched by the local processing units.

摘要： A method comprises receiving scene model data including a scene geometry model and a plurality of pixel data describing objects arranged in a scene. The method generates a primary ray based on a selected first pixel data. In the event the primary ray intersects an object in the scene, the method determines primary hit color data and generates a plurality of secondary rays. The method groups the secondary packets and arranges the packets in a queue based on the octant of each direction vector in the secondary ray packet. The method generates secondary color data based on the secondary ray packets in the queue and generates a pixel color based on the primary hit color data, and the secondary color data. The method generates an image based on the pixel color for the pixel data.
