Finite Element Integration with Quadrature on the GPU [article]

Matthew G. Knepley and Karl Rupp and Andy R. Terrel
2016 arXiv   pre-print
The total number of cells is N cells = (# of chunks)N chunk + N R , where N R is the number of remainder cells which are always processed on the CPU.  ...  Since N R is less than the chunk size N chunk , it is vanishingly small compared to the total number of elements.  ...

ManyClaw: Slicing and dicing Riemann solvers for next generation highly parallel architectures [article]

Andy R. Terrel, Kyle T. Mandli
2013 arXiv   pre-print
Next generation computer architectures will include order of magnitude more intra-node parallelism; however, many application programmers have a difficult time keeping their codes current with the state-of-the-art machines. In this context, we analyze Hyperbolic PDE solvers, which are used in the solution of many important applications in science and engineering. We present ManyClaw, a project intended to explore the exploitation of intra-node parallelism in hyperbolic PDE solvers via the

Topological Optimization of the Evaluation of Finite Element Matrices

Robert C. Kirby, Anders Logg, L. Ridgway Scott, Andy R. Terrel
2006 SIAM Journal on Scientific Computing  
We present a topological framework for finding low-flop algorithms for evaluating element stiffness matrices associated with multilinear forms for finite element methods posed over straight-sided affine domains. This framework relies on phrasing the computation on each element as the contraction of each collection of reference element tensors with an element-specific geometric tensor. We then present a new concept of complexity-reducing relations that serve as distance relations between these

We present experimental results for some common multilinear forms showing significant reductions in operation count and also discuss some efficient algorithms for building the graph we use for the optimization.

2017 International Journal of Telerehabilitation  
Telehealth is a broad term used to describe the use of electronic or digital information and communications technologies to support clinical healthcare, patient and professional health related education, and public health and health administration. Telerehabilitation refers to the delivery of rehabilitation and habilitation services via information and communication technologies (ICT), also commonly referred to as" telehealth" technologies. Telerehabilitation services can include evaluation,

Telerehabilitation services can be deployed across all patient populations and multiple healthcare settings including clinics, homes, schools, or community-based worksites. This document was adapted from the American Telemedicine Association's (ATA) "A Blueprint for Telerehabilitation Guidelines" (2010) and reflects the current utilization of telerehabilitation services. It was developed collaboratively by members of the ATA Telerehabilitation Special Interest Group, with input and guidance from other practitioners in the field, strategic stakeholders, and ATA staff. Its purpose is to inform and assist practitioners in providing effective and secure services that are based on client needs, current empirical evidence, and available technologies. Rehabilitation professionals, in conjunction with professional associations and other organizations are encouraged to use this document as a resource for developing discipline-specific standards, guidelines, and practice requirements.Keywords: American Telemedicine Association, Habilitation, Rehabilitation, Telehealth, Telepractice

2017 PeerJ Computer Science  
SymPy is an open source computer algebra system written in pure Python. It is built with a focus on extensibility and ease of use, through both interactive and programmatic applications. These characteristics have led SymPy to become a popular symbolic library for the scientific Python ecosystem. This paper presents the architecture of SymPy, a description of its features, and a discussion of select submodules. The supplementary material provide additional examples and further outline details of the architecture and features of SymPy.

Nutrition and health in amphibian husbandry

2014 Zoo Biology  
Amphibian biology is intricate, and there are many inter-related factors that need to be understood before establishing successful Conservation Breeding Programs (CBPs). Nutritional needs of amphibians are highly integrated with disease and their husbandry needs, and the diversity of developmental stages, natural habitats, and feeding strategies result in many different recommendations for proper care and feeding. This review identifies several areas where there is substantial room for

Using a scientific or research framework to answer questions about disease, nutrition, husbandry, genetics, and endocrinology of ex situ amphibians will improve specialists' understanding of the needs of these species. In general, there is a lack of baseline data and comparative information Zoo Biology 9999 : 1-17 (2014) for most basic aspects of amphibian biology as well as standardized laboratory approaches. Instituting a formalized research approach in multiple scientific disciplines will be beneficial not only to the management of current ex situ populations, but also in moving forward with future conservation and reintroduction projects. This overview of gaps in knowledge concerning ex situ amphibian care should serve as a foundation for much needed future research in these areas. Zoo Biol. XX:XX-XX, 2014.
