There is little point to building expensive exaflop-class computing machines if applications are not available to exploit the tremendous scale and parallelism. Consider that exaflop-class supercomputers will exhibit billion-way parallelism, and that calculations will be restricted by energy consumption, heat generation, and data movement. This level of complexity is sufficient to stymy application development, which Read more…
A team of scientists and mathematicians at the DOE’s Lawrence Berkeley National Laboratory are using powerful NERSC supercomputers together with sophisticated algorithms to create cleaner combustion technologies.
Documents made public by former intelligence analyst Edward Snowden reveal that the National Security Agency (NSA) has thwarted or circumvented many of the privacy safeguards of the Internet as part of a highly classified program codenamed Bullrun…
Today’s Wall Street is run by quantitative analysts who write the algorithms that run on the supercomputers that make the actual trades, using super high speed network connections to exchanges. While the new system has unquestionably enriched some, the question becomes: Has it benefited the rest of us?
This week the Linux Foundation released a special report about its role over the last twenty years of the Top500, pointing to some significant trends that helped it switch places with Unix (which once had a 96% share of the list) in roughly a one-decade timeframe. For instance, there are a few….
When researchers in Germany sat down nearly a decade ago to create a brand new parallel file system for HPC clusters, they had three goals: maximum scalability, maximum flexibility, and ease of use. What they came up with was the Fraunhofer Parallel File System (FhGFS), which is now in use on supercomputers.
Supercomputers are clearly important to the ability of the U.S. to compete on the global stage, but some members of Congress don’t understand that, Illinois Senator Dick Durbin said at the recent dedication of Mira, the IBM BlueGene/Q supercomputer installed last year at the Argonne National Laboratory in Illinois.
Outside of the main attractions, including the keynote sessions, vendor showdowns, Think Tank panels, BoFs, and tutorial elements, the International Supercomputing Conference has balanced its five-day agenda with some striking panels, discussions and topic areas that are worthy of some attention….
We’ve scoured the journals and conference proceedings to bring you the top research stories of the week. This diverse set of items includes advancements in petascale-era development environments; balancing performance with power efficiency; optimizing computer science instruction; and a possible path to extreme heterogeneity.
