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.
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
- 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 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 https://supporttickets.intel.com. 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.
