The SDSC Allocation Committee recently awarded 58,000 Paragon node-hours and 8,033 C90 hours to 29 research projects. Three of these projects are described below, indicating the variety and complexity of the scientific problems that researchers plan to tackle with the aid of supercomputers. Mihos also will investigate whether these events can account for the formation of the globular star clusters that surround many elliptical galaxies. Numerical simulations of galaxy evolution have become an important tool in astronomy. Mihos' calculations will involve the most realistic, detailed, and spatially resolved simulations of gravitational interaction, star formation, and gas dynamics ever performed.
Many zeolites have the ability to catalyze chemical reactions.
This catalytic ability has led to the wide use of zeolites in industry, where they are used to promote the formation of desired compounds and speed the breakdown of unwanted ones. Chakraborty's objective is to identify processes that can break down NO efficiently and directly, without the need for intermediate chemical reactions. Chakraborty will research the thermodynamic, geometrical, and electrochemical properties of NO interactions with zeolites. Direct Numerical Simulation of Turbulent Shear Flows in a Stratified Fluid Sarkar Sutanu of the Applied Mechanics and Engineering Sciences Department at UCSD will use SDSC's Cray C90 to perform numerical simulations of turbulent transport and turbulent mixing of ocean water. Simulations of turbulence are computationally demanding and require very high accuracy to obtain meaningful results.
