Abstract:
I will present our cut-cell block-structured adaptive mesh
refinement (AMR) computational fluid dynamics model and its
application to the study of highly nonlinear multiscale
environmental flows. The model is based on the solution of the

Abstract:
Many predictions for the high end systems of 2018 envision computers
with 227 CPUs. The construction of such machines represents a break
with the progress of HPC: if we take a baseline to 1991, we can see
that machines at that time were being designed with 29 CPUs, and we
will see machines with 220 cores in 2012 (21 years, 11 bits in the

Yahoo! today announced that it has expanded its partnerships with top U.S. universities to advance cloud computing research. The University of California at Berkeley, Cornell University and the University of Massachusetts at Amherst will join Carnegie Mellon University in using Yahoo!’s cloud computing cluster to conduct large-scale systems software research and explore new applications that analyze Internet-scale data sets, ranging from voting records to online news sources.
Computing Sciences Job Opportunity
BERKELEY LAB IS HIRING!
Whether running trillions of calculations on a supercomputer or
analyzing and visualizing massive datasets, scientists today rely on
advances in computer science, mathematics and computational science, as
well as large-scale computing and networking facilities, to increase our
understanding of ourselves, our planet and our universe. Berkeley Lab's
Computing Sciences organization researches, develops and deploys new
tools and technologies to meet these needs and to advance research in
