Parallel-processing experiences on the denelcor HEP computer

A collection of parallel linear equations routines for the Denelcor HEP

This paper describes the implementation and performance results for a few standard linear algebra routines on the Denelcor HEP computer. The algorithms used here are based on high-level modules that facilitate portability and perform efficiently in a xvide range of environments:The modules are chosen to be of a large enough computational granularity so that reasonably optimum performance may be...

Computer architecture and parallel processing

The HEP Parallel Processor

A lthough there is an abundance of concepts for parallel computing, there is a dearth of experimental data delineating their strengths and weaknesses. Consequently, for the past three years personnel in the Laboratory’s Computing Division have been conducting experiments on a few parallel computing systems. The data thus far are uniformly positive in supporting the idea that parallel processing...

Bulk Processing of Text on a Massively Parallel Computer

Dictionary lookup is a computational activity that can be greatly accelerated when performed on large amounts of text by a parallel computer such as the Connection Machine T M Computer (CM). Several algorithms for parallel dictionary lookup are discussed, including one that allows the CM to lookup words at a rate 450 times that of lookup on a Symbolics 3600 Lisp Machine. 1 An Overv iew of the D...

Parallel image and video processing on distributed computer systems

The aim of the paper is to validate architectures that allow an image processing researcher to develop parallel applications. A comparative analysis of the possible software and hardware solutions for real-time image and video processing was presented, with emphasis on distributed computing. The challenge was to develop algorithms that perform real-time low level operations on digital images ab...
