Intel® VTune™ Amplifier uses kernel drivers to enable hardware event-based sampling and collect event-based sampling data from. During the hardware event-based sampling (EBS), also known as analysis in the sampling mode, the Intel® VTune™ Amplifier profiles your. To enable hardware event-based sampling analysis on your platform, the Intel® VTune™ Amplifier uses sampling drivers that require root.

Bottom-up – Memory Usage Window: Summary – Hardware Events Window: See more recipes here.
Guessed Stack Frames Problem: The minimal value of vtyne sampling interval for the user-mode sampling and tracing collection depends on the system: Share Tweet Share Send. You can access the sample code at https: Cannot Find File Window: Options – Result Location Pane: Options – General Pane: If you are building the sampling drivers from a fresh kernel source and want to use it for an existing target system, get the original key files and sign the sampling driver with the original key.

vtume The boot script can be disabled later by executing: Driverless Perf system-wide counting provides event counting statistics performed by one monitoring process for the whole system over an interval.
This is only required if the permissions are other than or For more complete information about compiler optimizations, see our Optimization Notice. Runs an application only once and multiplexes the event groups in a round robin fashion during the run.
Intel VTune Amplifier Pane: Sample Count – Hardware Events Window: Make sure that the kernel tvune sources are present on your host system. Summary – Hardware Events Window: Bandwidth – Platform Power Analysis Window: Identify where your application is spending time, detect the most time-consuming program units and how they were called.
Intel VTune Amplifier Pane: Please send your feedback to parallel. Make sure the following options are enabled in the kernel configuration for hardware event-based sampling EBS collection: If the uncore events support is available on the system, the VTune Amplifier also uses the Perf collection for Memory Access, HPC Performance Characterization, and Microarchitecture Exploration analysis types with the Analyze memory bandwidth option enabled.
Call Stack Pane Context Menus: But if something happened for very little time, then very few samples will exist for it. If drivers are loaded, but you are not a member of the group listed in the query output, request your system administrator to add you to the group.
