Extreme Scaling of Production Visualization Software on Diverse Architectures

This month’s issue of the IEEE Computer Graphics & Applications journal is dedicated to “Ultrascale Visualization”, all about visualizing massive datasets across some of the largest computers in the world.  In particular, this issue contains the article about the massive “Trillion Zone” run of VisIt we discussed a while back.

A survey of powerful visualization techniques, from the obvious to the obscure

 

Thanks to advances in sensing, networking, and data management, our society is producing digital information at an astonishing rate. According to one estimate, in 2010 alone we will generate 1,200 exabytes—60 million times the content of the Library of Congress. Within this deluge of data lies a wealth of valuable information on how we conduct our businesses, governments, and personal lives. To put the information to good use, we must find ways to explore, relate, and communicate the data meaningfully.

The goal of visualization is to aid our understanding of data by leveraging the human visual system’s highly tuned ability to see patterns, spot trends, and identify outliers. Well-designed visual representations can replace cognitive calculations with simple perceptual inferences and improve comprehension, memory, and decision making. By making data more accessible and appealing, visual representations may also help engage more diverse audiences in exploration and analysis. The challenge is to create effective and engaging visualizations that are appropriate to the data.
