If you would like to register a PTS Global account, all that's needed is a user-name, password, and e-mail address. Once you've registered, check your email and click on the verification link and then you're all set. For easy log-in support, you'll need to check out the latest git code (.tar.gz of latest PTS code) -- unless of course you're reading this after PTS 0.4.0+ has been released. Running phoronix-test-suite login will prompt you to enter your user-name and password.
If you have any questions, concerns, or feature requests for PTS Global, head on over to the Phoronix Forums.
