We describe the use of a reconngurable interface board based on FPGAs and a UNIX workstation to implement a correlation tracker with 3.8ms latency. The correlation tracker is part of an active mirror system in use at the The reconngurable interface is used to leverage the workstation CPU, relieving it of tasks that it performs poorly such as rapid context switching and low-level bit manipulatio...

The design of a transfer line is considered. This line is used for a repetitive execution of a given set of operations to produce identical items. The line is composed of a sequence of workstations equipped with processing modules (blocks). Each block performs specific operations. The machined items move along the workstations in the same direction. There is the same cost associated with each w...

We describe our experiences with a very high-level parallel composition language (called GLU) that enables rapid construction of parallel applications using sequential building blocks (extracted from existing sequential applications) and their execution on diverse parallel computer systems. GLU is suuciently rich to succinctly express diierent forms of parallelism | from function parallelism to...

Data parallel programming languages offer ease of programming and debugging and scalability of parallel programs to increasing numbers of processors. Unfortunately, the usefulness of these languages for non-scientific programmers and loosely coupled parallel machines is currently limited. In this paper, we present the composite tree model which seeks to provide greater flexibility via parallel ...

Many image processing tasks exhibit a high degree of data locality and parallelism and map quite readily to specialized massively parallel computing hardware. However, as distributed memory machines are becoming a viable and economical parallel computing resource, it is important to understand how to use these environments for parallel image processing as well. In this paper we discuss our impl...

JJPF (the Java/Jini Parallel Framework) is a framework that can run stream parallel applications on several parallel-distributed architectures. JJPF is actually a distributed execution server. It uses JINI to recruit the computational resources needed to compute parallel applications. Parallel applications can be run on JJPF provided they exploit parallelism accordingly to an arbitrary nesting ...

Graphics Processing Units (GPUs) are being heavily used in various graphics and non-graphics applications. Many practical problems in computing can be represented as graphs to arrive at a particular solution. These graphs contains very large number, up to millions pairs of vertices and edges. In this paper, we present performance analysis of Dijkstra’s single source shortest path algorithm over...

The computational and compositional features are very important while constructing parallel software for the workstation clusters. However, lack of suitable supporting environment for parallel software development makes most existing distributed parallel software systems very weak in these two aspects, especially in the compositional feature. In this paper, a distributed object based framework ...
