In the computational world, where speed is king, fifteen zeros is the current frontier. The new wave of petascale supercomputers going online around the world in the coming months are capable of performing at least one quadrillion, or 1,000,000,000,000,000, floating calculations per second. In exponential notation, a quadrillion is shortened to 1 x 10^15, so clever computer scientists declared October 15th (get it?) to be Petascale Day, a celebration of this new computational land speed record and its ability to transform science.
Here at the Computation Institute, we observed the day by hosting a lunch event with the University of Chicago Research Computing Center, putting together a roster of six talks about these powerful machines and the new types of research they will enable. The speakers, who hailed from Argonne National Laboratory, the University of Chicago, and the Computation Institute, talked about the exciting potential of the petascale, as well as the technical challenges scientists face to get the most out of the latest supercomputers.
