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.

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... ;-)

SPICE up at

SPICE does not need any introduction in the Electronic Design Automation industry. In over 30 years of its life, SPICE has become the de-facto standard for circuit simulation.

ngspice is a mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice. Ngspice is part of gEDA project, a full GPL'd suite of Electronic Design Automation tools.
Circuit Simulation using

Good news -- ng-spice is now available in the Application Catalog. The design automation engineers can run circuit simulation simultaneously on multiple CPUs in the Sun Grid Compute Utility environment, and the simulation gets done much faster. Check out this page on how to run ngspice in

Brookhaven National Laboratory selects for its computational needs

For years science research labs and organizations have been researching, simulating and recreating phenomenon’s occurring in our world for environmental discovery, medical research, the history of our universe and human life. This research commands high power computing ability to run, analyze, and store such recreations and information.

Recently Sun Grid Compute Utility, a computing infrastructure that provides massive computational needs on an on-demand basis, has been powering the Brookhaven National Laboratory Solenoidal Tracker (STAR) project taking place at the Relativistic Heavy Ion Collider (RHIC). Brookhaven National Laboratory has recently ported STARSIM, the mainstay simulation application for the STAR project, to the Solaris 10 OS to take advantage of the computational power provided by Sun Grid Compute Utility (available from Sun Microsystems' and is approaching the next frontiers in their studies of the "perfect liquid" formed from nuclear matter under extreme conditions. The pay-as-you-use model offered by Sun Grid Compute Utility is helping move Brookhaven National Laboratory’s simulation effort forward efficiently and without any additional infrastructure investment.

Wednesday Jul 25, 2007 powers innovative drug discovery application

In today's competitive pharmaceutical marketplace, making a scientific breakthrough and getting to market first is vital to maximize revenue potential. Identifying quality lead compounds is an important but time-consuming task along the path of drug discovery. Constraints on compute power can often impede progress. The innovative Electronic High Throughput Screening (eHiTS) software from SimBioSys running on the powerful Sun Grid Compute Utility (offered by Sun's gives organizations a new way to accomplish fast, accurate docking of ligands to target receptors by using a secure, affordable, and scalable on-demand compute utility resource.

eHiTS offers new approaches to accurately score ligand and receptor interactions as well as to account for all conformation and protonation changes that occur during the binding process in the molecular docking and screening steps of drug discovery. The application fills the drug discovery pipeline faster by automating searches of compound libraries, identifying lead candidates rapidly, and reducing time to solve molecular docking challenges with the scalable power of its innovative algorithms running on Sun Grid Compute Utility.

Get the details about the eHiTS application offered via here.
