摘要

我们描述Chromium,一个在工作站集群上操作图形API命令流的系统。Chromium的流过滤器可以被安排来创建优先排序和最后排序的并行图形架构,在许多情况下,在只使用普通图形加速器的情况下支持相同的应用程序。此外,这些流过滤器可以通过编程方式进行扩展,允许用户自定义由集群中的节点执行的流转换。因为我们的流处理机制是完全通用的,所以任何集群并行渲染算法都可以在Chromium之上实现或嵌入到Chromium中。在本文中,我们给出了使用Chromium在工作站集群上实现良好可伸缩性的实际应用示例,并描述了这种流处理技术的其他潜在用途。通过完全抽象底层图形架构、网络拓扑和API命令处理语义,我们允许各种应用程序在不同的环境中运行。

Chromium: a stream-processing framework for interactive rendering on clusters
We describe Chromium, a system for manipulating streams of graphics API commands on clusters of workstations. Chromium's stream filters can be arranged to create sort-first and sort-last parallel graphics architectures that, in many cases, support the same applications while using only commodity graphics accelerators. In addition, these stream filters can be extended programmatically, allowing the user to customize the stream transformations performed by nodes in a cluster. Because our stream processing mechanism is completely general, any cluster-parallel rendering algorithm can be either implemented on top of or embedded in Chromium. In this paper, we give examples of real-world applications that use Chromium to achieve good scalability on clusters of workstations, and describe other potential uses of this stream processing technology. By completely abstracting the underlying graphics architecture, network topology, and API command processing semantics, we allow a variety of applications to run in different environments.
