A computing system capable of parallelizing the operation of multiple graphics processing units (GPUs) supported on external graphics cards, employing a multi-mode parallel graphics rendering subsystem having software and hardware implemented components, with image recomposition being carried out within or across two or more of the GPUs. 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, and (iii) a bridge circuit operably connecting one or more CPUs and the CPU memory space. The computing system also includes (iv) one or more graphics cards supporting multiple GPUs and being connected to the bridge circuit by way of a data communication interface, (v) a multi-mode parallel graphics rendering subsystem supporting multiple modes of parallel operation, (vi) a plurality of graphic processing pipelines (GPPLs), implemented using the GPUs, and (vii) 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.
