Compiling an optimized ATLAS on Ubuntu 12.04

1. Download the latest ATLAS source from http://sourceforge.net/projects/math-atlas/files/. I'm using version 3.10.1
2. Download the latest Netlib LAPACK from http://www.netlib.org/lapack/. I'm using version 3.4.2
3. Turn off frequency scalings on your chip so that you can get reliable timings. This is essential to get a good ATLAS build

  sudo apt-get install cpufreq-info cpuspeed cpufrequtils sysfsutils
  # set each core to the "performance" governor, so that the clock frequency doesn't go down when idle
  # I have 8 cores, which is why I need to do this 8 times
  sudo cpufreq-selector -c 0 -g performance
