Tremendous effort has been extended by the computer graphics community to advance the level of realism of material appearance reproduction by incorporating increasingly more advanced techniques. We are now able to re-enact the complicated interplay ...

We present new, simple, fully distributed, practical algorithms with linear time communication cost for irregular gather and scatter operations in which processors contribute or consume possibly different amounts of data. In a homogeneous, linear cost ...

With widening vectors and the proliferation of advanced vector instructions in today's processors, vectorization plays an ever-increasing role in delivering application performance. Achieving the performance potential of this vector hardware has ...

Digital x-ray acquisition allows the sophisticated processing of acquired images before display to the reader, making possible such operations as the removal in software of the systematic blurring effect of scatter. A method for analysing scatter ...

Wind power plant installations at different scales are in an increasing pattern starting from year 2000. A curiosity has been raised about 4-5 years ago for if wind turbines interfere with radars. The interference occurs when wind turbines reflect radar ...

This paper reports on a further development of an image simulation chain, and in particular, the inclusion of contrast degradation across an image using scatter to primary ratios calculated using Monte Carlo simulation The Monte Carlo technique, using ...

Variable selection is a very vital step of models making and prediction researching. In order to solve the problem of variable selection in complicated system, statistical and neural network theory are combined to propose a method of scatter determine ...

Gather and scatter are two fundamental data-parallel operations, where a large number of data items are read (gathered) from or are written (scattered) to given locations. In this paper, we study these two operations on graphics processing units (GPUs).

HeteroMPI is an extension of MPI designed for high performance computing on heterogeneous networks of computers. The recent new feature of HeteroMPI is the optimized version of collective communications. The optimization is based on a novel performance ...

Gather and scatter are data redistribution functions of long-standing importance to high performance computing. In this paper, we present a highly-general array operator with powerful gather and scatter capabilities unmatched by other array languages. ...

It is shown that Stable Matching problems are the same as problems about stable configurations of X-networks. Consequences include easy proofs of old theorems, a new simple algorithm for finding a stable matching, an understanding of the difference ...
