CUDA Implementation of a Navier-Stokes Solver on Multi-GPU Desktop Platforms for Incompressible Flows

Abstract: Graphics processor units (GPU) that are traditionally designed for graphics rendering have emerged as massively-parallel "co-processors" to the central processing unit (CPU). Small-footprint desktop supercomputers with hundreds of cores that can deliver teraflops peak performance at the price of conventional workstations have been realized. A computational fluid dynamics (CFD) simulation capability with rapid computational turnaround time has the potential to transform engineer ing analysis and design optimization procedures. We describe the implementation of a Navier-Stokes solver for incompressible fluid flow using desktop platforms equipped with multi-GPUs. Specifically, NVIDIA’s Compute Unified Device Architecture (CUDA) programming model is used to implement the discretized form of the governing equations. The pr ojection algorithm to solve the incompressible fluid flow equations is divided into distinct CUDA kernels, and a unique implementation that exploits the memory hierarchy of the CUDA programming model is suggested. Using a quad-GPU platform, we observe two orders of magnitude speedup relative to a serial CPU implementation. Our result s demonstrate that multi-GPU desktops can serve as a cost-effective small-footprint paral lel computing platform to accelerate CFD simulations substantially.

Incivility in Nursing Education: A Descriptive Study of Definitions and Prevalence

Abstract: Evidence suggests that incivility on American college campuses, ranging from insulting remarks and verbal abuse to violence, is a serious and growing concern. Faculty and students are often unsure how to address these behaviors. Therefore, 32 (88.9%) nursing faculty and 324 (69.4%) nursing students at one university completed a survey to gather their perceptions of student and faculty behaviors that may be considered uncivil. Student behaviors most frequently reported as uncivil by faculty included making disapproving groans, making sarcastic remarks or gestures, not paying attention in class, dominating class discussions, using cell phones during class, and cheating on examinations. The majority of faculty reported that uncivil student behaviors occurred rarely or sometimes. Examples of faculty behaviors considered uncivil by students included canceling class without warning, being unprepared for class, not allowing open discussion, being disinterested or cold, belittling or taunting students, delivering fast-paced lectures, and not being available outside of class. Students perceived incivility as a moderate problem in the nursing academic environment. It is imperative that nurse educators help students and faculty cope effectively with these behaviors; the authors discuss strategies to do so.

A Theoretical and Practical Framework for Service-Learning in Marketing: Kolb’s Experiential Learning Cycle

Abstract: The purpose of this article is to provide a framework for the design and implementation of service-learning courses in marketing. First, this article describes an experiential learning framework to be used as a guide for planning, designing, implementing, and evaluating a service-learning course. Second, this article specifies in detail service-learning implementation strategies for particular marketing courses. Third, this article describes actual methodology and outcomes of a service-learning case history for a consumer behavior course.

The lower Lesser Himalayan sequence: A Paleoproterozoic arc on the northern margin of the Indian plate

Abstract: The lower Lesser Himalayan sequence marks the northern extremity of the exposed Indian plate, and is generally interpreted as a passive margin. Five lines of evidence, however, collectively suggest a continental arc setting: (1) igneous intrusions and volcanic rocks occur at this stratigraphic level across the length of the Himalaya, (2) ages of intrusive and metavolcanic (?) rocks cluster at 1780–1880 Ma but also indicate a long-lived igneous process, (3) detrital zircon ages in clastic rocks cluster at 1800–1900 Ma, with a unimodal age distribution in some rocks, (4) the mineralogy and chemistry of metasedimentary rocks differ from typical shales and suggest a volcanogenic source, (5) trace-element chemistries of orthogneisses and metabasalts are more consistent with either an arc or a collisional setting. Intercalation of volcanic rocks with clastic sediments and a general absence of Proterozoic metamorphic ages do not support a collisional origin. An arc model further underscores the profound unconformity separating lower-upper Lesser Himalayan rocks, indicating that a Paleoproterozoic arc may have formed the stratigraphic base of the northern Indian margin. This, in turn, may indicate disposition of the Indian plate adjacent to North America in the ca. 1800 Ma supercontinent Columbia. Felsic orthogneisses (“Ulleri”) likely represent shallow intrusions, not Indian basement.
