Use the Intel® VTune™ Amplifier installed on the Windows* or Linux* host to analyze code performance and power consumption on remote systems. For example, this is a basic usage mode for the VTune Amplifier for Systems, a part of Intel® System Studio 2014, that provides performance analysis of applications running on Linux embedded platforms and Android* devices.
Note
Power analysis on embedded Linux systems is available via the VTune Amplifier GUI. To run Power analysis on an Android system, use the Intel® Energy Profiler. See the collateral documentation for details.
VTune Amplifier supports the following usage modes for remote analysis:
Remote Usage Mode with VTune Amplifier Remote Collector and SSH/ADB Communication
Requirements for the target system: ~25 MB disk space
This mode is recommended for most cross-development scenarios. It is also the only possible usage mode if your target system is resource-constrained (insufficient disk space, memory, or CPU power) or if you use a highly customized Linux target system.
To collect data on a remote embedded Linux system:
1. | Install VTune Amplifier | Install the full-scale VTune Amplifier product on the host system. |
2. |

4. | View the collected data on the host. |
To collect data on an Android system:
1. | Install VTune Amplifier | Install the full-scale VTune Amplifier product on the host system. By default, the VTune Amplifier also installs the remote collector on the target Android system as soon as you run the first remote collection. Note

Native Usage Mode
Requirements for the target system: ~200 MB disk space.
This mode is recommended for regular Linux target systems from supported operating systems listed in the product Release notes. In this mode, you install the full-scale VTune Amplifier product on the host system and install the command line interface of the VTune Amplifier, amplxe-cl, on the target system, which enables you to run native data collection directly on the target and collect all types of performance data supported by the VTune Amplifier, including all algorithmic analysis types.
The following figure shows an overview of the remote analysis that is run with amplxe-cl directly on the target system:
In the native usage mode, workflow steps to configure and run analysis on a remote system are similar to the remote collector mode.
