Researchers Start Lining Up for Blue Waters
It will be sometime next year before researchers can utilize the world's fastest supercomputer on University of Illinois Urbana campus -- but there's already a list of teams who will have first dibs when Blue Waters comes on line. And the U of I's National Center for Supercomputing Applications is seeking applications for more through mid-March.
Blue Waters is the result of a collaboration between the U of I and National Science Foundation, which is providing monetary awards to those researchers.
NCSA spokeswoman Trish Barker says it will take some time for research teams to adjust from a machine that does trillions of calculations each second to one that does a quadrillion every second. She says that will require an understanding of the huge computer's applications, or codes, in the same way we would use a common consumer program.
"They're written to run on supercomputers -- that means that things have been parallelized so that programs are sort of broken up and different pieces of them are being run on different parts of the supercomputer that are communicating with each other," Barker said. But those have to scale up now to take advantage of many many more processors than they're currently using. It's kind of like if you've tried to think about, I've used Microsoft Word on one computer -- what if I wanted to use it on five computers?
The first 18 teams learning Blue Waters' codes includes a group from the U of I's department of atmospheric sciences to build a tornado model. And another group on campus will study molecular dynamics.
Barker says the NSF awards are partially for travel... allowing teams to all meet on campus to begin researching the programming code for when Blue Waters comes on line. Some of the funding is also dedicated to getting the teams together to prepare their research.
