A processing unit (PU) retrieves a file from system memory and loads it into its internal memory. The PU extracts a processor type from the file's header which identifies whether the file should execute on the PU or a synergistic processing unit (SPU). If an SPU should execute the file, the PU DMA's the file to the SPU for execution. In one embodiment, the file is a combined file which includes both PU and SPU code. In this embodiment, the PU identifies one or more section headers included in the file which indicates embedded SPU code within the combined file. In this embodiment, the PU extracts the SPU code from the combined file and DMA's the extracted code to an SPU for execution.

A method for managing multiple processors in the execution of one or more processes in a task-based library platform. The one or more processes are partitioned into highly granulized sub-tasks from a library calling process, whereby each sub-task has a protection attribute associated with it. The protection attribute designates processing resources that a processor may use in the execution of the sub-task. The sub-tasks are placed in a central task queue, whereby idling processors in the multiple processor system obtain consecutive sub-tasks in the queue until all the processes have been executed. Each processor executes a sub-task using only those processing resources that have been designated as being available by the protection attribute of the sub-task. The atomic execution results of the one more sub-tasks may then be combined into an execution result for the process. Also provided is a task-based library for processor management.

Loading software on a plurality of processors is presented. A processing unit (PU) retrieves a file from system memory and loads it into its internal memory. The PU extracts a processor type from the file's header which identifies whether the file should execute on the PU or a synergistic processing unit (SPU). If an SPU should execute the file, the PU DMA's the file to the SPU for execution. In one embodiment, the file is a combined file which includes both PU and SPU code.

A task-based library framework for load balancing using a system task queue in a tightly-coupled multiprocessor system. The system memory holds a queue of system tasks. The library processors fetch tasks from the queue for execution. The library processors fetch the tasks when they have a light load. A library processor can fetch a task while executing another task.

The present invention provides for rendering photorealistic 3D viewing angles. Lighting values are approximated across selected viewing angles. In fixed lighting situations, approximating across viewing angles allows rendering of a high order lighting detail with complex surfaces. A polynomial equation representing the surfaces will be solved for the coefficients to be used in the formula of the fixed viewing angle. If the number of light sources is too high only specular and diffusion surfaces can be efficiently calculated in the polynomial equation.

The present invention is a method for integrating multiple object codes from heterogeneous architectures. For a program on a first processor to reference a program from the name space of a second processor, the object code for the second-processor program is enclosed in a wrapper to create object code in the first-processor name space. The header of the wrapped object code defines a new symbol in the name space of the first processor, and the symbol points to the second-processor object code contained in the wrapped object code. Instead of directly referencing the second-processor object code, the referencing program on the first processor references the wrapped object code. A system tool can be used to wrap the object code which runs on the second processor.

Systems and methods are provided for deploying new software application features as a dynamically-loadable executable package including one or more dynamically-linked shared dependent libraries. The dynamically-loadable executable package may be capable of being loaded into volatile memory and executed in an information handling system environment with or without the dependent shared libraries, and without duplicating the presence or use of redundant shared libraries that may be already present on the existing software stack.
