Adaptive Mesh Refinement Algorithms Create Computational Microscope

January 26, 1998

Computer modeling algorithms which break large problems into small pieces, and then focus computing power on those areas of the most scientific interest are helping scientists better understand such everyday situations as running an internal combustion engine, flying in an airplane or predicting weather. The axiom that big problems are much easier to tackle when divided into much smaller tasks is especially true when solving problems in fluid dynamics. Called adaptive mesh refinement… Read More »


A Flaw in the Law

January 26, 1998

Turbulence is a primal force that can be seen all around us, from the scudding of clouds to the frothing of the sea, from the wrinkling of flames to the swirling of leaves. It is especially important to the study of aerodynamics, in which correctly calculating the effects of turbulence can determine whether or not an airplane remains aloft. Since 1938, the standard equation presented in aerodynamics and engineering textbooks for calculating the forces exerted on a solid object by turbulence has… Read More »

Berkeley Lab, Pittsburgh Supercomputing Center to Study Network Congestion

July 23, 1997

For all the Internet users who wonder why e-mail sometimes bogs down or it takes so long to call up a favorite Web site, a new study by computer scientists in Berkeley and Pittsburgh may turn up some answers. According to Vern Paxson of Ernest Orlando Lawrence Berkeley National Laboratory, the year-long study funded by the National Science Foundation could help with troubleshooting problems on the Internet and eventually give users a method to rate the offerings of Internet service providers.

Berkeley Lab's Math Department Crosses, Stretches Boundaries

June 23, 1997

When it comes to boundaries, Berkeley Lab’s Mathematics Department usually straddles them, often blurs them and frequently stretches them to new levels. For example, the group has one foot planted firmly on the Hill in the Computing Sciences organization and the other on the UC Berkeley campus. The nature of the math department’s work comes down firmly in both the camps of mathematics and scientific computing. And in carrying out their applied math research, members of the department… Read More »

ESnet to Support Wide Range of Demos at SC14

When an estimated 10,000 high performance computing and networking experts from around the world converge on New Orleans for the SC14 conference looking for the latest developments, ESnet will play a major role in keeping everyone connected. A number of demonstrations at the conference will also be supported by ESnet, including a project led by Caltech to demonstrate terabit-level networking. Read More »
