Based on these results, Qtip calculates the score. + +Proposed change +=============== +Qtip has a flexible architecture [2]_ to support different mode: standalone and agent. +It is recommended to use **agent mode** to work with existing test runners.

Qtip could +create a suite named **Qtip-PoC** in Yardstick repo to verify workflow of Qtip agent mode. + +2. Launch Qtip in Yardstick + +Whether to launch Qtip will be determined by checking the existence of OS environment +variable *QTIP*.
