随着图形处理器(GPU)从仅用来进行图形图像渲染,脱离成为并行计算平台通用图形处理器(GPGPU),其计算能力越来越强,本文在研究GPGPU体系结构的基础上对GPGPU并行计算线程调度进行深入研究,阐述了GPU线程调度原理,揭示了SIMT调度模式的不足.通过公式推导阐述了系统功耗与系统运行频率的关系.%The Graphics Processing Unit (GPU) only is been used to the graphics image rendering,so it becomes a parallel computing platform General Purpose GPU(GPGPU),the parallel computing power is growing,and the application is more and more widely.Based on the study of GPGPU architecture,the GPGPU parallel computing thread scheduling is studies,and the principle of GPU thread scheduling and the deficiency of SIMT scheduling mode are introduced.The relationship between system power consumption and system operating frequency is expounded by formula.
