Sun's renders computer-animated movie "Big Buck Bunny"

Over the weekend, the "Big Buck Bunny" movie was released online. It is an "open movie" -- a very interesting concept. And we were a part of it!

Check out the details here.

Predict that tornado at!

The Weather Research and Forecasting (WRF) model is a computer program with a dual use for forecasting and research. It is the latest numerical program model to be adopted by the National Weather Service as well as the U.S. military and private meteorological services.

The model features multiple dynamical cores, a 3-dimensional variational (3DVAR) data assimilation system, and a software architecture allowing for computational parallelism and system extensibility. In other words, WRF is an excellent candidate for tapping in the enormous compute power provided by the Sun Grid Compute Utility at

Sun engineers have made WRF available via the Application Catalog, and the instructions of running the application in the grid environment can be found here.

Smoke and Fire at

Fire Dynamics Simulator (FDS), a computer program for modeling fire and smoke flow, is now available from the Application Catalog. FDS numerically solves a form of the Navier-Stokes equations appropriate for low-speed, thermally driven flow with an emphasis on smoke and heat transport from fires.

(OK, that's a very fancy way of saying it needs to solve complicated differential equations that are very compute intensive and lends themselves beautifully for processing in a grid utility. ;-) )

FDS is developed by NIST, and is used for fire and smoke modeling for animation (think FDS when you see cars going up flames in a Pixar movie), sprinkler activation in warehouse fires, tenability in residential fires, and smoke concentration in outdoor pool fires.

Bottom line, it is a very useful program for predicting smoke and fire. Learn more about it in Application Catalog, and if you are a developer/modeler, here is how to run the program at

How is evolving?

Derrick Harris of Grid Today is writing a two-part article on the origin of utility computing and how it has evolved over the years. Sun's is positioned as grid computing for the masses, but you'd get ample hints of what's coming down the pike... ;-)

Computer Aided Engineering made easy at Application Catalog has a number of useful finite element analysis tools that are widely used in Computer Aided Engineering.

Calculix is one of these free software applications -- it does nonlinear three dimensional finite element analysis for structural applications like static structure problems (bridge and building design), buckling, dynamic applications (crash, earthquake resistance) and eigenmode analysis (resonance phenomena). Calculix comes with a preprocessor to generate and mesh the structures, and a postprocessor to view the results by means of contour plots and animation. Kinda fancy, if you ask me. :-)

Now Calculix is an ideal choice for running on Sun Grid Compute Utility as it is an compute intensive application. The team has ported Calculix to run on the Sun Grid, and the results of running this application on the grid as compared with those running serially are really encouraging.

If you're an CAE engineer trying to run finite element analysis, check out this site to learn how to run this application on with your own data.

Thursday Sep 06, 2007 powering Brookhaven National Laboratory featured in CHEP conference

As I mentioned in the past, Brookhaven National Laboratory relies on for their on-demand grid computing infrastructure. I am pleased to say that Sun and Brookhaven National Laboratory have been asked to present their partnership at the International Conference on Computing in High Energy and Nuclear Physics. Taking place this week, the CHEP conference provides an international forum to exchange information on computing experience and needs for the community, and to review recent, ongoing, and future activities.

A detailed case study on powering Brookhaven National Laboratory is now available -- check it out.
