Remote Performance Analysis Workflow for Linux* Systems

VTune Amplifier supports the following usage modes for remote analysis of Linux applications on regular and embedded systems:

• Remote CLI (amplxe-cl) or GUI (amplxe-gui) (recommended for regular and embedded systems)

• Native CLI with installing and running amplxe-cl directly on a remote Linux system

• Native SEP with sep (recommended for tiny embedded systems)

Remote CLI and GUI Usage Mode

Requirements for the target system: ~25 MB disk space

This mode is recommended for most cross-development scenarios supported by the VTune Amplifier for Systems, especially 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 with the VTune Amplifier for Systems:

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.

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 collectors mode.

Native Sampling Collector (SEP) Usage Mode

Sampling сollector (SEP) is a command-line tool for hardware event-based sampling analysis targeted for resource-restricted systems. The SEP package is delivered as part of the target package of the VTune Amplifier for Systems. The SEP package contains both sep utilities and the sepdk source code (for pax.ko and sep3_xx.ko) to build the sampling drivers.

To use SEP, you need just to extract the SEP package from system_studio_target.tgz file, build the driver and upload both driver and sep utilities to the target, and then collect the event-based sampling performance data in command line. See SEP_Users_Guide.pdf for more details.
