Preface In the past decade there has been a dramatic shift from mainframe or 'host−centric' computing to a distributed 'client−server' approach. In the next few years this trend is likely to continue with further shifts towards 'network−centric' computing becoming apparent. All these trends were set in motion by the invention of the mass−reproducible(More)
This paper evaluates the High-Performance Fortran (HPF) language as a candidate for implementing scientiic, engineering and computer science software on parallel machines. The paper reviews major HPF language features and discusses general algorithmic issues common to broad classes of SPMD applications. It also discusses limitations of the current(More)
Since the deenition of the High Performance Fortran HPF standard, we have been maintaining a suite of application kernel codes with the aim of using them to evaluate the available compilers. This paper presents the results and conclusions from this study, for sixteen codes, on compilers from IBM, DEC, and the Portland Group Inc. PGI, and on three machines:(More)
We describe our InfoMall technology transfer program | a partnership of over sixty commercial, academic and federal organisations working together on HPCN technology development a s w ell as HPCN-enabled business activities. We discuss a selection of some of the project activities being undertaken by InfoMall members and focus on an \Electronic InfoMall"(More)
In October of 1997, a year-long collaborative project was started between Hitachi Europe Limited (HEL) and the Edinburgh Parallel Computing Centre (EPCC) at the University of Edinburgh. This project had the goal of producing an environment whereby Java programs may be executed on the Hitachi SR2201 distributed memory multi-processor machine. The two key(More)
The surge in the popularity of the World Wide Web (WWW) has corresponded to a decreasing market for specialised high performance computers. This paper discusses how, by making use of technology developed from the broader end of the computing pyramid, much of the past decade's work in distributed computing can be realised in the context of the larger WWW(More)
reveal biotin labelling at the injection sites. Rhodamine-labelled cells in the retina were visualized in vitro with a green filter block (excitation filter 545 nm, barrier filter 590 nm). The fluorescent label, initially confined to small bright spots in the soma and proximal dendrites, diffused throughout the entire dendritic tree after brief light(More)
Light stimuli from a 100-W tungsten source were filtered (neutral density and narrow-band interference filters;10 nm width; Oriel), gated by a shutter (Uniblitz VS35;Vincent Associates) and calibrated by a radiometer (S370, UDT Instruments). The irradiance of the unfiltered ('white') stimulus was (in photons s 21 cm 22): 4 £ 10 12 at 400 nm, 6 £ 10 13 at(More)
