We need a visitor from the third dimension, preaching the gospel of chip stacking to the denizens of chip…

When Petascale Is Just Too Slow
Evolution or revolution, it’s the persistent question. Can we build reliable exascale systems from extrapolations of current technology or will new approaches be required? There is no definitive answer, as almost any approach might be made to work at some level with enough heroic effort. The bigger question is what design would enable the most…

Scientific Clouds: Blowin’ in the Wind
Cirrus, stratus, altostratus, cumulus: they are the scientific names of the common clouds. They drift across the sky, reflecting the changing wind and weather. A new front is blowing into computational science, and cloud computing will soon advance scientific and engineering discovery.

Blogging at CACM Also
Several of us will be blogging for the new CACM web site, offering perspectives on science policy, research, computing technology and societal implications. Look for me at the CACM web site soon, under Blog@CACM. (And yes, I will continue to blog on Reed’s Ruminations at www.hpcdan.org as well.)
