摘要:

随着云游戏和云虚拟现实(VR)的日益普及,交互式3D应用程序已成为云的主要工作负载类型。然而,尽管它们的重要性越来越大,但由于缺乏开放和可靠的研究基础设施,包括基准测试和性能分析工具,关于如何设计云系统以有效支持这些应用程序的公共研究有限。在各种系统/应用程序随机性下生成类似人类的输入以及剖析复杂图形系统的性能的挑战使得设计这样的基础设施非常困难。在本文中,我们提出了一种新的云图形绘制研究基础设施,Pictor的设计。Pictor使用人工智能来模拟人类与复杂3D应用程序的交互。它还可以为用于云3D图形渲染的复杂软件和硬件堆栈提供深入的性能测量。使用Pictor,我们设计了一个包含六个交互式3D应用程序的基准套件。使用这些基准进行性能分析,以描述云中的3D应用程序并揭示新的性能瓶颈。为了证明Pictor的有效性,我们还实现了两个优化,以解决在最先进的云3D图形渲染系统中发现的两个性能瓶颈,这将帧速率平均提高了57.7%。

英文摘要:

With the growing popularity of cloud gaming and cloud virtual reality (VR), interactive 3D applications have become a major type of workloads for the cloud. However, despite their growing importance, there is limited public research on how to design cloud systems to efficiently support these applications, due to the lack of an open and reliable research infrastructure, including benchmarks and performance analysis tools. The challenges of generating human-like inputs under various system/application randomness and dissecting the performance of complex graphics systems make it very difficult to design such an infrastructure. In this paper, we present the design of a novel cloud graphics rendering research infrastructure, Pictor. Pictor employs AI to mimic human interactions with complex 3D applications. It can also provide in-depth performance measurements for the complex software and hardware stack used for cloud 3D graphics rendering. With Pictor, we designed a benchmark suite with six interactive 3D applications. Performance analyses were conducted with these benchmarks to characterize 3D applications in the cloud and reveal new performance bottlenecks. To demonstrate the effectiveness of Pictor, we also implemented two optimizations to address two performance bottlenecks discovered in a state-of-the-art cloud 3D-graphics rendering system, which improved the frame rate by 57.7% on average.
