I was at a talk about the SKA project on Tuesday night here in
Melbourne, and it touched on just this problem.

They need about 7PF of FFTs alone.

Unfortunately the top scorer on the Global FFT benchmark (part of the
HPC challenge suite) is the K machine (10PF on HPL) which clocks almost
206TF, about 40 times less than what they need.
