Burning questions (April 16, 2007)
Powerful computers are simulating how turbulence enhances – or retards –
combustion in clean, efficient engines. A grant of 2.5 million processor hours
from the Department of Energy’s INCITE program made the model possible.

From deep freeze to furnace (June 4, 2007)
A researcher is modeling what happens when hydrogen pellets frozen
to near absolute zero are shot into a plasma more than six times hotter
than the sun. What he’s learning could help lead to
clean, abundant energy.

Oil crisis stalled cars, but jump-started a
supercomputing revolution
(July 31, 2007)
The oil embargo of 1973 forever changed the way Americans
think about energy – and it altered the path of
scientific research. Alvin Trivelpiece had a lot to do with
that change.

MADNESS makes sense (April 16, 2007)
A mathematical software framework called MADNESS could
help scientists study and simulate systems previously thought
nearly impossible. It has potential applications in energy,
drug development and other fields.

Big Iron:
Speed bump (April 16, 2007)
Computer scientists helped bump up the speed with which a combustion simulation program
ran by as much as 10 times. The simulation ran on some of the world’s most
powerful high-performance computers.

Sniffing out bad code (April 16, 2007)
A program designed to find and fix bad computer codes now is
finding malicious programming and maintaining software on some
of the world’s biggest computers.

Calculating error pollution (April 16, 2007)
University of Texas researchers are out to make computer
simulations more precise with mathematical methods to estimate
errors. Potential results include smaller, faster
electronics, cures for disease, and other applications.

Digging up FOSLS (June 4, 2007)
A technique devised by a University of Colorado mathematician unravels
complex equations, letting computers solve them more quickly and
efficiently. He’s applied it to models of blood flow
and pressure in the eye.

Collaborative effort helps optimize cavities in accelerators
(April 16, 2007)
When they’re miles around and buried underground, it’s tough to improve
particle-smashing accelerators – unless you use simulation, as a
collaboration between computer researchers and physicists did.

Genealogy:
Message passing passage (April 16, 2007)
The big computers of today might not have been possible
if some dedicated experts hadn’t gathered at an
“unappetizing” hotel in the 1990s. The
standard they created is used on virtually every high-performance
computer today.

Computing climate (June 18, 2007)
When it comes to improving computer climate models and making
them run on powerful machines, one Department of Energy program
was the CHAMMP. Models it improved more than a decade ago
still contribute to global climate change science.
