Abstract
Parallel processing is ubiquitous with modern computer systems. This has been supported by two major hardware advances: on the one hand, computer CPUs nowadays include several processing cores, even mobile devices CPUs. On the other hand, the adoption of parallel processing has been bolstered in recent years thanks to the parallel processing capacities of graphics processing units (GPUs). General-purpose computing on graphics processing units (GPGPU) is one example. Relying on the DirectX 12 framework, we propose in this paper a novel approach to enable parallel processing for graphical rendering on both the CPU and GPU for the popular Racket functional programming language (formerly PLT Scheme), and importantly without compromising the usability and programmer-friendliness of Racket. Our performance evaluations show significant improvements with respect to execution time (x3 speed-up in some cases), CPU utilisation time (reduced by as much as 80% in some scenarios) and the frame rate when using animated graphics.
