A View of Parallel Computing
The task of estimating the number of distinct values (DVs)in a large dataset arises in a wide variety of settings in com-puter science and elsewhere. We provide DV estimationtechniques for the case in which the dataset of interest issplit into partitions. We create for each partition a synop-sis that can be used to estimate the number of DVs in thepartition. By combi...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولPerformance and Portability in Parallel Computing: a Weather Forecast View
We have developed a high level library, the Nearest Neighbor Tool (NNT), to facilitate the coding of finite difference approximation weather prediction models on parallel computers. NNT provides portability and ease of programming and at the same time optimizes performance by allowing the overlap of computation and communication to tolerate the latency of remote data moves. In this paper we des...
متن کاملA new view of the Vesalian landscape.
OF all medical books, the De humani corporisfabrica of Andreas Vesalius in its two folio editions of 1543 and 1555 has probably been the object of most study and attention. Even today when its difficult late Latin and the absence of a full English translation make it inaccessible to all but a small number of scholars, its woodcut illustrations are still familiar to any one with the slightest in...
متن کاملA New View of the Cosmic Landscape
In this scenario, a generic meta-stable deSitter vacuum site in the cosmic landscape in string theory has a very short lifetime. Typically, the smaller is the vacuum energy of a meta-stable site, the longer is its lifetime. This view of the landscape can provide a qualitative dynamical explanation why the dark energy of our universe is so small. The argument for this scenario is based on resona...
