Analyze Unplugged Devices

Configure the
Intel® VTune™
Profiler
to run the collection on a detached device by using the
Analyze unplugged device
option.
Intel VTune
Profiler
allows you to run an analysis on a mobile system that is detached from the network or USB drive during the collection. Detaching the device from an ADB connection allows for increased accuracy in certain system performance metrics, such as power consumption. Unplugged analysis is currently supported for Android* target devices.
  1. Connect to the target Android device via ADB. For more information, see Android* System Setup.
  2. Click the
    Configure Analysis
    button on the
    VTune
    Profiler
    toolbar.
  3. Select the
    Android device (ADB)
    option from the
    WHERE
    pane.
  4. In the
    WHAT
    pane, select the analysis target.
  5. Expand the
    Advanced
    section of the
    WHAT
    pane and select the
    Analyze unplugged device
    option.
  6. Select the analysis type from the
    HOW
    pane and click
    Start
    .
  7. Unplug the device from the USB.
    Collection begins as soon as the device is disconnected. Data is collected on the device using the settings selected. An alert appears after collection completes. You can also tap the
    Stop
    button on your device to stop the collection.
  8. Reconnect the device to the USB when collection completes. The collected results are automatically transferred to
    Intel VTune
    Profiler
    , processed, and displayed in the viewpoint appropriate to the analysis type selected. If you plug in the device before collection completes, the collection stops and the results are transferred to
    Intel VTune
    Profiler
    .

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
