云中的分布式图形仿真

Distributed Graphical Simulation in the Cloud

Omid Mashayekhi, Chinmayee Shah, Hang Qu, Andrew Lim, Philip Levis

摘要:

图形模拟是现代媒体和电影的基石。但是现有的软件包被设计为在HPC节点上运行,并且在计算云中表现不佳。这些模拟在复杂的数据结构上具有复杂的数据访问模式,并且任意地改变数据,因此不适合现有的云计算系统。我们描述了一种软件架构,用于在云中运行图形仿真,该架构可以简化控制逻辑、计算和数据交换。这允许中央控制器通过重新分配计算来平衡负载,并从故障中恢复。评估表明,该架构可以在存在落伍者和故障的情况下运行现有的最先进的模拟,从而使这一大类应用程序能够首次使用计算云。

英文摘要:

Graphical simulations are a cornerstone of modern media and films. But existing software packages are designed to run on HPC nodes, and perform poorly in the computing cloud. These simulations have complex data access patterns over complex data structures, and mutate data arbitrarily, and so are a poor fit for existing cloud computing systems. We describe a software architecture for running graphical simulations in the cloud that decouples control logic, computations and data exchanges. This allows a central controller to balance load by redistributing computations, and recover from failures. Evaluations show that the architecture can run existing, state-of-the-art simulations in the presence of stragglers and failures, thereby enabling this large class of applications to use the computing cloud for the first time.
