"Clouds modulate the climate. They reflect some sunlight back into space, which cools the Earth; but they can also act as a blanket and trap heat," says Michael Wehner, a climate scientist at the Lawrence Berkeley National Laboratory (Berkeley Lab). "Getting their effect on the climate system correct is critical to increasing confidence in projections of future climate change."
In order to build the breakthrough supercomputers scientists like Wehner need, researchers are looking to the world of consumer electronics like microwave ovens, cameras and cellphones, where everything from chips to batteries to software is optimized to the device's application. This co-design approach brings scientists and computer engineers into the supercomputer design process, so that systems are purpose-built for a scientific application, such as climate modeling, from the bottom up.
"Co-design allows us to design computers to answer specific questions, rather than limit our questions by available machines," says Wehner.
