We implement here a fast and memory-sparing probabilistic top <i>k</i> selection algorithm on the GPU. The algorithm proceeds via an iterative probabilistic guess-and-check process on pivots for a three-way partition. When the guess is correct, the problem is reduced to selection on a much smaller set. This probabilistic algorithm always gives a correct(More)
A statewide assessment was conducted of assaults, experiences, needs, and recommendations of 125 adult victims receiving care at 19 sexual assault centers (SACs) in the State of Maryland. More than one half of the victims (55.6%) waited years before disclosing, with delays in reporting especially likely if the assault was perpetrated by a family member (the(More)
This paper describes the first use of a network processing unit (NPU) to perform hardware-based image composition in a distributed rendering system. The image composition step is a notorious bottleneck in a clustered rendering system. Furthermore, image compositing algorithms do not necessarily scale as data size and number of nodes increase.

We get a B-ordering of all binary n-tuples Vn by choosing an ordered basis {y1,...,yn} of Vn and ordering the n-tuples as follows: 0, y1, y2, y2+y1, y3, y3+y1, y3+y2, y3+y2+y1, y4,... Given a minimum distance d, choose a set of vectors S with the zero vector first, then go through the vectors in their Bordering and choose the next vector which has distance(More)
Los Alamos National Laboratory (LANL) has deployed a 43megapixel multi-panel immersive environment, La Cueva Grande (LCG), to be used in visualizing the terabytes of data produced by simulations. This paper briefly discusses some of the technical challenges encountered and overcome during the deployment of a 43-million pixel immersive visualization(More)
The U.S. Department of Energy's (DOE) Office of Environmental Management (DOE/EM) currently supports an effort to understand and predict the fate of nuclear contaminants and their transport in natural and engineered systems. Geologists, hydrologists, physicists and computer scientists are working together to create models of existing nuclear waste sites, to(More)
Silent data corruptions (SDCs) are one of the most critical issues in modern HPC systems, as they are "silent" by definition and raise no warnings to users and application developers that a calculation has been corrupted. A significant amount of effort has been made to characterize, detect, and tolerate SDCs. However, current approaches do not share the(More)
