I am evaluating the rteval test to see whether it is a useful tool for us.

In the current form, it is not packaged, and depends upon a library which is not packaged. These instructions only work for Natty and later.

In order to install and run it on Ubuntu (Oneiric), these are the steps:

  1. Install the required packages:
    • sudo apt-get install python-ethtool python-libxslt1 python-dmidecode rt-tests python-dev git
  2. Install python-schedutils from source:
  3. Fetch and install rteval:
  4. Run rteval from terminal for generic kernel (for 6 minutes duration):
    • sudo python /usr/local/lib/python2.7/dist-packages/rteval/rteval.py -d360.0 > rteval-$USER-generic-normal.txt

    • this dumps the test results into a text file in your /home directory
  5. Run rteval from console (to check if cgroups affects test) for generic kernel (for 6 minutes duration):
    • clt-alt-F1 (to get to console)
    • log in
    • sudo python /usr/local/lib/python2.7/dist-packages/rteval/rteval.py -d360.0 > rteval-$USER-generic-console.txt

    • this dumps the test results into a text file in your /home directory
  6. Install -lowlatency kernel
    • install abogani's ppa from termainal
      • sudo add-apt-respository ppa:abogani/lowlatency
      • sudo apt-get update
      • sudo apt-get install linux-lowlatency
  7. Reboot
  8. Run rteval from terminal for lowlatency kernel (for 6 minutes duration):
    • sudo python /usr/local/lib/python2.7/dist-packages/rteval/rteval.py -d360.0 > rteval-$USER-lowlatency-normal.txt

    • this dumps the test results into a text file in your /home directory
  9. Run rteval from console (to check if cgroups affects test) for lowlatency kernel (for 6 minutes duration):
    • clt-alt-F1 (to get to console)
    • log in
    • sudo python /usr/local/lib/python2.7/dist-packages/rteval/rteval.py -d360.0 > rteval-$USER-lowlatency-console.txt

    • this dumps the test results into a text file in your /home directory
  10. email results to scottalavender@gmail.com, be sure to put 'rteval' in the subject line of the email.
