Accelerating the Sweep3D for a Graphic Processor Unit

Abstract: Abstract-As a powerful and flexible processor, the Graphic Processing Unit (GPU) can offer a great faculty in solving many high-performance computing applications. Sweep3D, which simulates a single group time-independent discrete ordinates (Sn) neutron transport deterministically on 3D Cartesian geometry space, represents the key part of a real ASCI application. The wavefront process for parallel computation in Sweep3D limits the concurrent threads on the GPU. In this paper, we present multi-dimensional optimi… Show more

“…In this paper, we propose a real-time traversable ground surface segmentation and intuitive representation system. To speed up the computation of the proposed methods, we used graphics processing unit (GPU) programming to implement the segmentation and modeling processes for large-scale datasets in parallel [10].…”

“…In recent times, with the rapid development of graphics cards, a graphics processing unit (GPU) with a highly parallel many-core architecture has been widely used in 2D image processing, 3D data analysis, visualization, and other fields [ 8 , 9 ]. GPU programming can be used to realize a high-speed and high-quality large-scale terrain reconstruction system [ 10 ].…”

“…General-Purpose GPU is a highly parallel, multithreaded, many-core processor with a very high computational power and memory bandwidth [3]. GPU architecture is designed for optimization of massively parallel computing, because of this architectural difference, a GPU is in general more advantageous for large-scale parallel data processing applications than general-purpose CPUs [4], and the high performance computing community leveraging a GPU can yield performance increases of several orders of magnitude [5,6]. High-performance computing with GPUs is called GPU computing [7].…”
