Data Sorting World Record — 1 Terabyte, 1 Minute
An anonymous reader writes "Computer scientists from the University of California, San Diego have broken the 'terabyte barrier' — and a world record — when they sorted more than a trillion bytes of data in 60 seconds. During this 2010 'Sort Benchmark' competition, a sort of 'World Cup of data sorting,' the UCSD team also tied a world record for fastest data sorting rate, sifting through one trillion data records in 172 minutes — and did so using just a quarter of the computing resources of the other record holder."
I had a 6502 system with BASIC in ROM and a machine code monitor. The idea is to copy a page (256 bytes) from the BASIC ROM to the video card address space. This puts random characters into one quarter of the screen. Then bubble sort the 256 bytes. It took about one second.
For extra difficulty do it again with the full 1K of video. Thats harder with the 6502 because you have to use vectors in RAM for the addresses. So reads and writes are a two step operation, as is incrementing the address. You have to test for carry. But the result was spectacular.

You've got to be kidding me. Each node was only 2 quad core processors, with 16 500GB drives (big potential disk IO per node) but this system doesn't even begin to scratch the very bottom of the top 500 list.
I just can't image that if even the bottom rung of the top 500 was even slightly interested in this record, that they wouldn't blow this team out of the water.
The cesspool just got a check and balance.
I think this is cool, but.... how fast is it in a more practical situation?
