Abstract
The issue of halo communication is the decrease of parallel scalability. To overcome the issues, we have introduced "Halo thread" to our simulation code. However, we have not solved the issue basically in the strong scaling. In this study, we have developed the Halo functions which perform the halo communication effectively. Then we can perform the calculation and communication in a pipeline and obtained good performance.

Opacity Volume Based Halo Generation for Enhancing Depth Perception
CADGRAPHICS '11: Proceedings of the 2011 12th International Conference on Computer-Aided Design and Computer GraphicsHalos are usually used to enhance depth perception and display spatial relationships in illustrative visualization. In this paper, we present a simple and effective method to create volumetric halo illustration. In the pre-processing stage, we generate ...
Halo control for LHE based local adaptive tone mapping
2015 IEEE International Conference on Image Processing (ICIP)We propose a halo control method that is suitable for smoothed local histogram equalization (LHE). Smoothed LHE based tone mapping, e.g., Apical Iridix®, is effective and widely used for local adaptive image enhancement. However, halo artifacts ...
Halo-free image enhancement through multi-scale detail sharpening and single-scale contrast stretching
AbstractConventional image enhancement methods manipulate images in just one scale. This is usually not enough in practice since details like edges live across scales. So, enhancing images through multiscale manipulations is necessary to ...
