In this paper we investigate performance of global communications in a particular parallel code. The code simulates dynamics of expansion of premixed spherical flames using an asymptotic model of Sivashinsky type and a spectral numerical algorithm. As a result, the code heavily relies on global all-to-all interprocessor communications implementing transposition of the distributed data array in ...

This paper presents original research about the behaviours, histories, demographics, and motivations of scholars who code, specifically how they interact with version control systems locally on Web. By understanding patrons through multiple lenses – daily productivity habits, motivations, scholarly needs librarians archivists can tailor services for software management, curation, long-term reus...

BACKGROUND The active recruitment of health workers from developing countries to developed countries has become a major threat to global health. In an effort to manage this migration, the 63rd World Health Assembly adopted the World Health Organization (WHO) Global Code of Practice on the International Recruitment of Health Personnel in May 2010. While the Code has been lauded as the first glob...

Projections indicate a global workforce shortage of approximately 4.3 million across the health professions. The need to ensure an adequate supply of health workers worldwide has created a context for the increased global migration of these professionals. The global trend in the migration of health professionals has given rise to the international recruitment industry to facilitate the passage ...

Protecting children from injuries caused by fall accidents from playground equipment is important. Therefore, measures toward minimizing the risk of fall accident injuries are required. The risk of injury can be evaluated using ASTM F1292. In this test, G-max and the HIC are used to estimate the risk of injury. However, the measurement procedure is too complicated for application to a large num...

Published papers rarely disclose implementation details. In this paper we show how such details can account for speedups of up to a factor of 28 for different implementations of the same algorithm. We perform an in-depth analysis of the most popular benchmark in heuristic search: the 15-puzzle. We study implementation choices in C++ for both IDA* and A* using the Manhattan distance heuristic. R...

The May 2010 adoption of the World Health Organization Global Code of Practice on the International Recruitment of Health Personnel created a global architecture, including ethical norms and institutional and legal arrangements, to guide international cooperation and serve as a platform for continuing dialogue on the critical problem of health worker migration. Highlighting the contribution of ...
