The Intel® VTune™ Amplifier product team is investigating the impact of recent OS security updates. We are providing initial guidance which will allow you to continue using VTune Amplifier 2018 Update 1 and earlier.

On Windows* and Linux*, the VTune Amplifier analyses using precise events or hardware event-based sampling with stacks may cause an application or system crash. We recommend that you do not use such analyses. These include:

  • Advanced Hotspots with stacks
  • All analyses listed under microarchitecture analysis
  • HPC Performance Characterization
  • Custom Analysis that uses the collect stacks option or precise events

The following analyses do not use event-based sampling with stacks or precise events and work correctly:

  • Basic Hotspots
  • Concurrency
  • Locks and Waits
  • Platform analysis

On Linux, Perf-based (driverless) collection is not affected by the OS security updates and will work correctly for all analyses. Uninstall the VTune Amplifier sampling driver to enable perf-based collection. See instructions for uninstalling the VTune Amplifier sampling driver.

In addition, building the sampling driver may fail on kernels > 4.13

If you continue to experience issues, please submit a ticket at the Online Service Center. For information on security updates, see Intel.com Security Center site.

We are working on Intel® VTune™ Amplifier product updates which will restore proper operation.  We will keep you posted on product updates as they become available. Stay tuned.
