In this paper we study the resource requirements of electrooptical organizations in performing digital computing tasks. We define a generic model of parallel computation using optical interconnects, called the optical model of computation (OMC). In this model, computation is performed in digital electronics and communication is performed using free space(More)
In this paper, we study tools for design and mapping of portable parallel programs. An essential component of such a tool is a mapping algorithm which can map arbitrary program tasks onto arbitrary computer systems. A generic fast recursive mapping algorithm, which is part of the Cluster-M parallel programming tool, is presented. This algorithm is suitable(More)
We have presented architectural and communication issues in designing large-scale heterogeneous parallel systems using passive star-coupled optical interconnection. It has been shown that the no-code-migration task scheduling strategy generally performs better than the subtask-code-migration strategy. This shows that increases in the capacity and the I/O(More)
In this paper, we introduce the Systolic Reconngurable Mesh (SRM), which combines aspects of the reconngurable mesh with that of systolic arrays. Every processor controls a local switch that can be reconngured during every clock cycle in order to control the physical connections between its four bi-directional bus lines. Data is input from one side of the(More)
1 A preliminary version of this paper appeared in the edited volume entitled "Parallel Architectures and Algorithms for Image Understanding" by V. ABSTRACT In this paper we present an overview of the impact of optical technology on parallel image computing. We study a few eecient and simple optical organizations for a set of preprocess-ing tasks such as(More)
