I think their point was this:<p><pre><code>  When using a Pico FPGA cluster, however, each FPGA is able
  to perform 1.6 billion DES operations per second. A cluster
  of 176 FPGAs, installed into a single server using standard
  PCI Express slots, is capable of processing more than 280
  billion DES operations per second. This means that a key
  recovery that would take years to perform on a PC, even
  with GPU acceleration, could be accomplished in less than 
  three days on the FPGA cluster.

So, they managed to brute-force DES a lot faster. No crypto breakthrough, please move along. :)<p>This should have been titled "FPGA cluster brute-forces DES in record time" or something like that.
