Configuring an Analysis Type for Intel® Xeon Phi™ Coprocessor

Click the New Analysis button on the VTune Amplifier toolbar.

The New Amplifier Result tab opens with the Analysis Type window active.

The corresponding configuration pane opens on the right.

VTune Amplifier collects samples for a list of events predefined in the analysis configuration. You may change this list by creating a new custom configuration: New Knights Corner Hardware Event-based Sampling Analysis.

The number of hardware events that can be collected simultaneously is limited by CPU capabilities. It is no more than two events on an Intel Xeon Phi coprocessor card. To overcome this limitation, the VTune Amplifier splits the event list into several event groups. Each group consists of events that can be collected simultaneously. VTune Amplifier uses one of the following techniques:

• Runs an application only once and multiplexes the event groups in a round-robin fashion during the run (default mode). This mode is supported with Intel Manycore Platform Software Stack 2.2 Alpha 2 and later.

• Runs an application several times collecting one event group during each run to achieve more precise results. To enable this mode in the GUI, set the Allow multiple runs option in the Advanced section of Project Properties dialog box.
