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)
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)
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)
BACKGROUND Acute psychiatric wards manage patients whose actions may threaten safety (conflict). Staff act to avert or minimise harm (containment). The Safewards model enabled the identification of ten interventions to reduce the frequency of both. OBJECTIVE To test the efficacy of these interventions. DESIGN A pragmatic cluster randomised controlled(More)
BACKGROUND Conflict (aggression, substance use, absconding, etc.) and containment (coerced medication, manual restraint, etc.) threaten the safety of patients and staff on psychiatric wards. Previous work has suggested that staff variables may be significant in explaining differences between wards in their rates of these behaviours, and that structure (ward(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)

BACKGROUND The purpose of this study was to explore the barriers and facilitators healthcare professionals experience when managing type 2 diabetes in people with severe mental illness (SMI). METHODS A qualitative semi-structured interview approach was employed. Questions were structured according to the Theoretical Domains Framework (TDF), which outlines(More)
BACKGROUND The collaborative care planning study (COCAPP) is a cross-national comparative study of care planning and coordination in community mental healthcare settings. The context and delivery of mental health care is diverging between the countries of England and Wales whilst retaining points of common interest, hence providing a rich geographical(More)
