We describe the FPGA HPC Alliance's Parallel Toolkit (PTK), an initial step towards the standardization of high-level configuration and APIs for high-performance reconfigurable computing (HPRC). We discuss the motivation and challenges of reaping the performance benefits of FPGAs for memory-bound HPC codes and describe the approach we have taken on the(More)
This paper reviews the current state of the art in high-performance reconfigurable computing (HPRC) from the perspective of EPCC, the high-performance computing centre at the University of Edinburgh. We look at architectural and programming trends and assess some of the challenges that HPRC needs to address in order to drive itself across the chasm from the(More)
We present the initial results from the FHPCA Supercomputer project at the University of Edinburgh. The project has successfully built a general-purpose 64 FPGA computer and ported to it three demonstration applications from the oil, medical and finance sectors. This paper describes in brief the machine itself – Maxwell – its hardware and software(More)
The aim of this study was to investigate upper body muscle activity during a 30 s Wingate test. Eighteen physically active participants performed a Wingate test while muscle activity was recorded from the brachioradialis (BR), biceps brachii (BB), triceps brachii (TB) and upper trapezius (UT). Measurements were obtained at rest, during a function maximal(More)
Production Grid infrastructure requires end-to- end guarantees on the Quality of Service from the underlying networks. In this paper, we present use cases for advance network resource reservation and then describe a multi-layered architecture that can support them. The architecture presents a single bandwidth broker, called BAR, which sits at the Grid(More)
This document contains an analysis of a major survey of HPC systems and applications across the PRACE 1 partners (see [1]). The survey data was used to produce an overall utilisation matrix characterised by scientific area and algorithm. This matrix represents one of the best snapshots of HPC utilisation produced, and could be an invaluable basis to predict(More)
Information on the health status and physical activity of Scottish adolescents is limited. This study examines the prevalence of cardiovascular disease (CVD) risk in Scottish adolescents by socioeconomic status (SES). Participants were recruited from two high schools that differed in the SES of the students in attendance. The sample included 73 boys and 34(More)
Grid application performance is inherently dependent on the performance and reliability of the underlying network. In a production Grid infrastructure, network performance monitoring (NPM) information is required both for middleware resource-brokering decisions and operational monitoring. A variety of NPM frameworks are available which can provide such(More)
