Abstract

In this paper we present the initial development of a streaming environment based on a programming model and machine description. The stream programming model consists of an extension to the C language and it's translation towards a streaming machine. The extensions will be a set of OpenMP-like directives. We show how a serial application can be converted into a streaming parallel application using the proposed annotations. We also show how the machine description can be used to parametrize a cost-model simulator to predict the performance of the stream program. The cost model allows the compiler to determine the best task partitioning and scheduling for each architecture.
