In supercomputing, it is often the case that top systems are only around for about half a decade. With the breaking of the petascale barrier now fixed in the rearview mirror of 2008, we are starting to see some of those ground-breaking systems reach their retirement age. It happened with Roadrunner, the world’s first petaflopper, not
It may not be possible to prevent devastating space-weather events like solar storms from reaching the earth’s surface, but with enough warning, we can prepare for them. Scientists believe that mapping the earth’s magnetosphere – the magnetic shield that stops most but not all of these storms – is the first step.
A diminutive marine crustacean called the Gribble landed on the biofuel industry’s radar for its unique ability to digest wood in salty conditions. Now, researchers in the US and the UK are putting the University of Tennessee’s Kraken supercomputer to work modeling an enzyme in the Gribble’s gut, which could unlock the key to developing better industrial enzymes in the future.
University of Oklahoma researcher zeros in on why some storms generate tornadoes while others don’t.
The large-scale classical physics problems that remain unsolved must for the most part be run in parallel by high-performance machines like the Kraken supercomputer. Literally millions of variables culled from billions of particles combine to make this type of research unreasonable for ordinary computational physics.
Researchers at the University of Oklahoma are finding ways to simulate tornado formation using more variables with help from supercomputers.
UT’s Kraken breaks petascale barrier for academia; and Cyprus Institute partners with University of Illinois. We recap those stories and more in our weekly wrapup.
