Abstract
A computing system capable of parallelizing the operation of multiple graphics processing units (GPUs) supported on a hybrid CPU/GPU fusion-architecture chip and/or on an external graphics card, and employing a multi-mode parallel graphics rendering subsystem having software and hardware implemented components. The computing system includes (i) CPU memory space for storing one or more graphics-based applications, (ii) one or more CPUs for executing the graphics-based applications, (iii) a multi-mode parallel graphics rendering subsystem supporting multiple modes of parallel operation, (iv) a plurality of graphic processing pipelines (GPPLs), implemented using the GPUs, and (vi) an automatic mode control module. During the run-time of the graphics-based application, the automatic mode control module automatically controls the mode of parallel operation of the multi-mode parallel graphics rendering subsystem so that the GPUs are driven in a parallelized manner.
