Lightweight threads have an important role to play in parallel systems: they can be used to exploit shared-memory parallelism, to mask communication and I/O latencies, to implement remote memory access, and to support task-parallel and irregular applications. In this paper, we address the question of how to integrate threads and communication in high-performance distributed-memory systems. We p...

Modern networked computing environments and applications often require|or can bene t from|the use of multiple communication substrates, transport mechanisms, and protocols, chosen according to where communication is directed, what is communicated, or when communication is performed. We propose techniques that allow multiple communication methods to be supported transparently in a single applica...

Rapid population increase coupled with urbanization and industrialization has resulted in shortages of water in the Middle East. This situation is further exacerbated by global climate change due to greenhouse gas emissions. Recent research advocates that solutions to the global water security and scarcity crisis must involve water-energy nexus approaches. This means adopting policies and strat...

BACKGROUND The purpose of this study was to better define the incidence and characteristics of patients with spinal cord injury without radiographic abnormality (SCIWORA), using the database of the National Emergency X-Radiography Utilization Study (NEXUS). METHODS This was a prospective, observational study of blunt trauma patients in 21 U.S. medical centers undergoing plain cervical radiogr...

This paper aims at contributing to the outline and to the practical addressing of the challenges posed to the study of collective action dynamics by the unprecedented level of embeddedness of Information and Communication Technologies (ICTs) in all domains of human action and, in particular, by the multiplication and the widespread use of social media. It does so in three steps. First, it addre...

The data presented here are manually encoded characteristics of research papers in the area of Energy-Economy Nexus (empirical investigation of Granger causality between energy consumption and economic growth) that describe the methods, samples, and other details related to the individual estimations done in the examined empirical papers. Data cover papers indexed by Scopus, published in econom...

In this paper, we present a new type of Globus resource allocation manager (GRAM) called RMF (Resource Manager beyond the Firewall) for wide-area cluster computing. RMFmanages computing resources such as cluster systems and enables utilization of them beyond the rewall in global computing environments. RMF consists of two basic modules, a remote job queuing system (Q system) and a resource allo...

We use the term ubiquitous supercomputing to refer to systems that integrate low-and mid-range computing systems, advanced networks, and remote high-end computers with the goal of enhancing the computational power accessible from local environments. Such systems promise to enable new applications in areas as diverse as smart instruments and collaborative environments. However, they also demand ...

Recently, much attention is given to financial-growth nexus, but largely via the physical capital accumulation channel. This study differed by examining this nexus, via the human capital accumulation channel in the ECOWAS region. It employed panel cointegration approaches as well as the FMOLS, DOLS. The results revealed that bank private credit and domestic private credit contribute significant...

nvironmental degradation can inflict serious damage on poor people, because their livelihoods often depend on natural resource use, and their living conditions may offer little protection from pollution of the air, water and soil. At the same time, poverty-constrained options may induce the poor to deplete resources and degrade the environment at rates that are incompatible with long-term susta...
