Low-Power Reconfigurable Architectures for High-Performance Mobile Nodes

Modern embedded systems have an emerging demand on high performance and low power circuits. Traditionally special functional units for each application are developed separately. These are plugged to a general purpose processors to extend its instruction set making it an application specific instruction set processor. As this strategy reaches its boundaries in area and complexity reconfigurable architectures propose to be more flexible. Thus combining both approaches to a reconfigurable application specific processor is going to be the upcoming solution for future embedded systems

EuroEXA - D2.6: Final ported application software

This document describes the ported software of the EuroEXA applications to the single CRDB testbed and it discusses the experiences extracted from porting and optimization activities that should be actively taken into account in future redesign and optimization. This document accompanies the ported application software, found in the EuroEXA private repository (https://github.com/euroexa). In particular, this document describes the status of the software for each of the EuroEXA applications, sketches the redesign and optimization strategy for each application, discusses issues and difficulties faced during the porting activities and the relative lesson learned. A few preliminary evaluation results have been presented, however the full evaluation will be discussed in deliverable 2.8

Psychometric Properties of the Greek Version of the Medical Office on Patient Safety Culture in Primary Care Settings.

BACKGROUND: Safety culture is considered one of the most crucial premises for further development of patient care in healthcare. During the eight-year economic crisis (2010-2018), Greece made significant reforms in the way the primary health care system operates, aiming at the more efficient operation of the system without degrading issues of safety and quality of the provided health services. In this context, this study aims to validate a specialized tool-the Medical Office Survey on Patient Safety Culture (MOSPSC)-developed by the Agency for Healthcare Research and Quality (AHRQ) to evaluate primary care settings in terms of safety culture and quality. METHODS: Factor analysis determined the correlation of the factor structure in Greek data with the original questionnaire. The relation of the factor analysis with the Cronbach’s coefficient alpha was also determined, including the construct validity. RESULTS: Eight composites with 34 items were extracted by exploratory factor analysis, with acceptable Cronbach’s alpha coefficients and good construct validity. Consequently, the composites jointly explained 62% of the variance in the responses. Five items were removed from the original version of the questionnaire. As a result, three out of the eight composites were a mixture of items from different compounds of the original tool. The composition of the five factors was similar to that in the original questionnaire. CONCLUSIONS: The MOSPSC tool in Greek primary healthcare settings can be used to assess patient safety culture in facilities across the country. From the study, the patient safety culture in Greece was positive, although few composites showed a negative correlation and needed improvement

Using MML to Simulate Multiple Dual-Ported SRAMs: Parallel Routing Lookups in an ATM Switch Controller

The need for fast parallel table lookups is evident in many modern hardware applications, such as network switches, hard disk controllers, and encryption devices. Typically, most of these table lookups are performed in fast and expensive on-board SRAMs in order to reduce latency. These SRAMs frequently provide dual-ported access at speeds of up to 20 ns. However, for applications demanding many large look-up tables, SRAM’s physical size, density, power requirements, and cost are prohibitive. In this paper, we address this problem through one particularly demanding example: the routing control in a sophisticated ATM switch. We present a design that uses merged memory and logic (MML, a modified form of DRAM) to simulate dual-ported SRAM in performing tens of table lookups in parallel. Our solution fits on one chip instead of over 300 required by an existing design, providing an integrated, low-power solution while still meeting the rigorous timing constraints of the application.

Co-designed Innovation and System for Resilient Exascale Computing in Europe: From Applications to Silicon (EuroEXA)

EuroEXA targets to provide the template for an upcoming exascale system by co-designing and implementing a petascale-level prototype with ground-breaking characteristics. To accomplish this, the project takes a holistic approach innovating both across the technology and the application/system software pillars. EuroEXA proposes a balanced architecture for compute and data-intensive applications, that builds on top of cost-efficient, modular-integration enabled by novel inter-die links, utilises a novel processing unit and embraces FPGA acceleration for computational, networking and storage operations. EuroEXA hardware designers work together with system software experts optimising the entire stack from language runtimes to low-level kernel drivers, and application developers that bring in a rich mix of key HPC applications from across climate/weather, physical/energy and life-science/bioinformatics domains to enable efficient system co-design and maximise the impact of the project
