Abstract

The Process-Oriented Dataflow System (PODS) is an execution model that combines the von Neumann and dataflow models of computation to gain the benefits of each. Central to PODS is the concept of array distribution and its effects on partitioning and mapping processes. In this paper, we present and discuss the results of executing the classic matrix multiply algorithm (with 1024 data points) on a PODS simulator. The key result is that PODS can take advantage of the parallelism in matrix multiply using a simple automated partitioning scheme.
