The need for increased computing power for rendering computer imagery is motivated and the sources from which it might de derived surveyed. Increased power can come from parallelism, as well as faster technology, implying new machine architectures and new algorithms. Surveys sketch early att~mpts at using available parallel architectures and look at the limitations and strengths of some existin...

A new type of STEM detector has been developed and tested. This detector consists of 30 rings which are split in quadrants (= 120 channels) and it allows to take further advantage of the image formation principle of STEM: the scattered electrons can be recorded separately according to their scattering angles and eight images can be acquired in parallel. Because of its electron counting capabili...

It is becoming increasingly apparent that some aspects of intelligent behavior require enormous computational power and that some sort of massively parallel computing architecture is the most plausible way to deliver sueh power. Parallelism, rather than raw speed of the computing elements. seems to be the way that the brain gets such jobs done. But even if the need for massive parallelism is ad...

With the shift in general purpose computing to increasingly parallel architectures comes a need for clever architectures to achieve high parallelism on previously sequential or poorly parallelized code. In order to fully utilize the many-core systems of the present and future, a shift must occur in architecture design philosophy to understanding how the parallel programming process affects desi...

The development of radar systems on general-purpose off-the-shelf parallel hardware represents an effective means of providing efficient implementations with reasonable realization costs. However, the fulfillment of the required real-time constraints poses serious problems of performance and efficiency: parallel architectures need to be exploited at best, providing scalable parallelizations abl...

OpenMP is emerging as a quasi-standard for shared memory parallel programming on small SMP-systems. To serve as a common programming interface in shared memory parallel programming, scalability to a larger number of nodes and support for different shared memory architectures has to be proven. In this paper we investigate how well the basic constructs of OpenMP are implemented on different paral...

The variety of parallel architectures nowadays available implies that models for parallel software development should deliver acceptable performance on a range of architectures with minimal development effort. One approach is to use languages with very high level, and substantially architecture-independent, specification of parallel coordination. This paper presents a novel profiling-based meth...
