A System for Parallel Media Processing
John A. Watlington and V. Michael Bove, Jr.
We describe a parallel computer system for processing media: audio,
video, and graphics, among others. The system supports medium to
coarse grain parallelism, using a dataflow model of execution, on a
range of machine architectures scaling from a single von Neumann or
general purpose processor (GPP) up to networks of several hundred
heterogeneous processors. A distributed resource manager, extending
subsuming the functionality of a traditional operating system, is an
integral and necessary part of the system. While we are building a
system for processing a variety of media, in this paper we concentrate
on video because it provides an extreme case in terms of both data
rates and available parallelism.
