Blue Waters visualization team provides first science images

The NCSA has just issued a press release showcasing some of the first scientific visualizations coming from the new Blue Waters machine.  Focusing on star formation, supernova, and Big Bang research, it’s a great collection of images and details on how petascale visualization is done. These collaborations have provided insight into the size and type […]

VisIt 2.3 Available

VisIt 2.3 is now available, boasting new cumulative queries in selections, and new file readers for VelodyneCLE AMR, Nek5000, and some Cale formats.  Support for Xdmf has improved, and they’ve got some exciting new features for parallel users: VisIt’s X launching and parallel GPU acceleration features have been rewritten to mesh better with modern cluster […]


Workshop on Visualization of Large Scientific Data

In just a few weeks, the CINECA supercomputing centre in Bologna, Italy will be hosting a Workshop on Visualization of Large Scientific Data. The scientific community is presently witnessing an unprecedented growth in the quality and quantity of data coming from simulations and real-world experiments. Moreover writing results of numerical simulations to disk files has […]

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 series of experiments studied […]

Hurricane Simulation Visualized with VisIt

While I have never been to Lawrence Livermore National Laboratory, I have been a fan of their VisIt visualization tool. Empisys generated this movie using Weather Research and Forecasting (WRF) simulation data published by the University Center for Atmospheric Research (UCAR) in Boulder, Colorado. This weather model simulates a large hurricane in the Gulf of […]

Open Invitation for VisIt Benchmark Ideas

After we reported on the inclusion of VisIt into the SuperComputing 2009 Student Cluster Competition, Hank Childs stopped by to post some information. As far as the benchmarks: the evaluation criteria is still being determined. From an HPC perspective, we obviously want to stress I/O, compute, and communication. My initial thoughts were to upsample a […]

SC09 Student Cluster Competition: Go Green!

The rules have been set for this year’s SuperComputing Student Cluster competition, and this year it’s all about “Go Green”. This year’s SC09 Student Cluster Competition is built around a “Go Green!” theme, tying it in with this year’s show. Just like the previous competition, this year’s rules have capped the overall power requirements of […]

VisWeek2009: VisIt Tutorial

On Monday afternoon I attended the VisIt Tutorial, taught by the ever-knowledgeable Sean Ahern and Hank Childs. The tutorial covered all the major parts you could hope for: Basic usage, advanced functionality, expressions, client-server, analysis, and finally development.  I thought I’ld cover some of the highlights for you in case you couldn’t make it yourself. […]

SC09 Visualization Tutorials

The guys at SuperComputing have published a list of the tutorials that will be underway on November 15th and 16th, and there’s a few Visualization tutorials you may want to check out if you’re in the Portland, OR area. Nov15 8:30am – noon : (S09) VisIt – Visualization & Analysis for Very Large Data Sets […]

Smashing the Trillion Zone Barrier

Details of the massive VisIt run announced a while back, are starting to come out, and while they still aren’t publishing any concrete details, you can find some interesting details about the systems and testing procedures used: The VACET team ran the experiments in April and May on six world-class supercomputers (latest TOP500 rankings noted): […]

DOE Researchers Push VisIt to the Limit

Researchers from several DOE labs attempted to visualize isosurfaces and volume renderings in parallel on 2-terapoint datasets using VisIt.
