The study of a prototype of the second-level triggering system for operation at LHC conditions is addressed by means of a parallel machine implementation. The 16 node transputer based machine uses a fast digital signal processor acting as a coprocessor for optimizing signal processing applications. A C-language development environment is used for running all applications at ultimate speed. The ...

In this paper, a new parallel processing system for commercial applications, so called SPAX, is described. SPAX cost-effectively overcomes the SMP limitation by providing scalability of the parallel processing system and application portability of the SMP. We also describe a new system network, so called XcentNet, which interconnects hundreds of multiprocessor PC boards in SPAX. It is a hierarc...

A prototype of an online event validation system is developed for application in a high energy collider experiment The system mainly uses neural net works for extracting rare events with physics sig ni cance from a huge background noise It is based on processing the information collected from dif ferent detectors placed around the collision point Combining a feature extraction phase for each de...

This paper discusses with the feasibility and value of a parallel image computing system for analyzing remotely sensed data on a Personal Computer Local Area Network. The design and configuration of the system are presented. The scheduling methods are also described. Examples of remote sensing analysis procedures that benefit from this type of systcm are illustrated. It is concluded that the pa...

There is a growing interest in sensorymotor integration for realizing new behavior of intelligent robots and there must be some processing architectures integrated with the detection function. When viewed from the system as a whole, a parallel processing architecture is produced in which a part of the processing is distributed among the sensors. As a result of this, it is strongly required that...

Object-relational database systems are now being deployed for real use by customers. Researchers and industry users have begun to explore the performance issues that these systems raise. In this paper, we examine some of those performance issues, and evaluate them for object-relational systems in general and for INFORMIX-Universal Server in particular. We describe objectrelational query process...

This paper proposes an extension of the traditional active disk concept by applying it to parallel file systems deployed in modern clusters. Utilizing processing power of the disk controller CPU for processing of data stored on the disk has been proposed in the previous decade. We have extended and deployed this idea in context of storage servers of a parallel file system, where substantial per...

The mechanisms of eye-movement control are among the best understood in motor neurophysiology. Detailed anatomical and physiological data have paved the way for theoretical models that have unified existing knowledge and suggested further experiments. These models have generally taken the form of black-box diagrams (for example, Robinson 1981) representing the flow of hypothetical signals betwe...

With the increased performance capabilities of desktop computers, networked computing has become a popular vehicle for using parallelism to solve a variety of computationally intense problems. However, node heterogeneity and high communication costs may limit performance unless the problem space is carefully partitioned across the network in a way that considers both the capabilities of the mac...

In this paper we discuss general requirements for parallel implementations of image processing algorithms. Of special importance are the communication demands in the parallel system which are determined by the algorithm under consideration. These communication demands are decisive for determining the best way to distribute the image data to the network processors. Analysing these factors for so...
