Gravitational tree-code on graphics processing units: implementation in CUDA

open access: yesProcedia Computer Science, 2010
We present a new very fast tree-code which runs on massively parallel Graphical Processing Units (GPU) with NVIDIA CUDA architecture. The tree-construction and calculation of multipole moments is carried out on the host CPU, while the force calculation which consists of tree walks and evaluation of interaction list is carried out on the GPU.

The Number of Huffman Codes, Compact Trees, and Sums of Unit Fractions

open access: yesIEEE Transactions on Information Theory, 2013
The number of "nonequivalent" Huffman codes of length r over an alphabet of size t has been studied frequently. Equivalently, the number of "nonequivalent" complete t-ary trees has been examined. We first survey the literature, unifying several independent approaches to the problem.

CtuNet: A Deep Learning-based Framework for Fast CTU Partitioning of H265/HEVC Intra- coding

open access: yesAin Shams Engineering Journal, 2021
Nowadays, real-time multimedia applications mandate high video quality while maintaining reasonable bitrates. The H.264 coding delivered inexpensive bitrate costs compared to other coding schemes while maintaining high-grade video quality, yet bounded to

Efficient H.264-to-HEVC Transcoding Based on Motion Propagation and Post-Order Traversal of Coding Tree Units [PDF]

open access: yesIEEE Transactions on Circuits and Systems for Video Technology, 2018
In this paper, we propose a fast H.264-to-HEVC transcoder composed of a motion propagation algorithm and a fast mode decision framework. The motion propagation algorithm creates a motion vector candidate list at the coding tree unit (CTU) level and, thereafter, selects the best candidate at the prediction unit level.
