The University of Texas at Austin (UT), along with the Texas A&M University, Texas Tech, and the University of Texas System, among others, has built the Lonestar 4 supercomputer, which contains 1,888 Dell blade servers, each with two Intel Xeon 5600 processors. The new supercomputer is expected to support more than 1,000 research projects over the next four years. The Lonestar 4 will perform 8 million trillion computer computations over its projected four-year lifespan.
Although Lonestar 4 does not have the total computer power of UT's Ranger, it could be faster because it uses more advanced processor chips and a faster network.
University of Tokyo researchers are using the computer to model the recent earthquake and tidal wave, as well as where radioactive water from the Fukushima Daiichi nuclear plant has dispersed in the ocean and the atmosphere.
UT president William Powers Jr. says high-performance computing as "the fuel on which much of the modern research university runs."
