In this paper we report our experiences in porting the FEASTFLOW software infrastructure to the Intel Xeon Phi coprocessor. Our efforts involved both the evaluation of programming models including OpenCL, POSIX threads and OpenMP and typical optimization strategies like parallelization and vectorization. Since the straightforward porting process of the(More)

The High-Performance Computing ecosystem consists of a large variety of execution platforms that demonstrate a wide diversity in hardware characteristics such as CPU architecture, memory organization, interconnection network, accelerators, etc. This environment also presents a number of hard boundaries (walls) for applications which limit software(More)
Aggressive therapy with statins to lower the low density lipoprotein cholesterol decreases cardiovascular events. Nevertheless, administration of the highest approved statin dose only offers limited additional benefit at the expense of an increased incidence of side effects. Therefore, novel compounds that further reduce the low-density lipoprotein(More)
INTRODUCTION we analysed the clinical profile of patients with an ST-elevation myocardial infarction (STEMI) who arrived in hospital within 12 hrs from pain onset and either received reperfusion therapy (PCI or fibrinolytic therapy) or remained without reperfusion. METHODS the Hellenic Infarction Observation Study (HELIOS) was a countrywide registry of(More)
This paper provides an overview of the state of the art technologies for software development in cloud environments. The surveyed systems cover the whole spectrum of cloud-based development including integrated programming environments, code repositories, software modeling, composition and documentation tools, and application management and orchestration.(More)
BACKGROUND Although atrial fibrillation (AF) is a highly prevalent health problem with high morbidity and mortality, data regarding the clinical characteristics and management of AF in the Greek population are scarce. The "Current Clinical Practice in the MANAGEment of Atrial Fibrillation in Greece" study (MANAGEAF) aimed to assess the epidemiological(More)
BACKGROUND The aim of the present interim analysis was to compare the clinical efficacy and safety of the generic clopidogrel besylate (CB) with the innovator clopidogrel hydrogen sulphate (CHS) salt in patient groups eligible to receive clopidogrel. METHODS A 2-arm, multicenter, open-label, phase 4 clinical trial. Consecutive patients (n=1,864) were(More)
