Numerical weather prediction on the one hand needs a very large number of floating point calculations, but on the other hand is very time-critical. Therefore, the largest computers available, i.e., the'supercomputers', have usually been acquired by t

Antiviruses are designed to inhibit virus replication and arrest infections. A particular antivirus derives from a specific virus, on which it depends for propagation. Antiviruses have a natural equivalent in defective interfering particles (DIPs). T

The Manchester Data-Flow Machine, MDFM, has evolved continuously during the past decade. By the time the prototype uniprocessor hardware system was decommissioned, in 1989, the putative multi-processor architecture comprised separate Processing Eleme

As the number of parallel processors in massively parallel systems increases, the need for concurrent tasks or processes also increases. In this study the author investigates the total parallelism inherent in NWP algorithms. The technique employed is

The shallow water equations have been used to test the behaviour of a variety of parallel computer systems in numerical weather prediction. The algorithm is fully vectorisable, but in its parallel form, requires a high degree of synchronisation and d

Several libraries for parallel processing on supercomputers are analyzed in terms of their parallel processing facilities, complexity, use, and how they reflect the hardware for which they were designed. A proposal for an objective measure of a libra

There have been many attempts to use FORTRAN as a language environment for parallel processing. In each case either the standard has been violated or some facilities have been left lacking and in most cases both. This paper briefly examines some of t
