Customize Data Collection for Intel® VTune™ Profiler Performance Analysis | Intel Software

Опубликовано 8 мая 2023, 14:00

This video demonstrates using Intel VTune Profiler together with a custom data collector to enable customized analysis.

It will demonstrate configuring the custom data collector to interact with the VTune data collection, and injecting custom data after collection has completed.
It also showcases how to augment regular hardware events-based sampling data and hotspot analysis data with your custom data collection results.

The Intel VTune Profiler provides the ability to augment performance analysis types such as the ones listed here:
• hotspots analysis to detect the functions that are consuming the most processor time
• threading analysis to analyze locks and waits such as semaphores, mutexes, and I/O waits
• system overview to explore system resource utilization
• HPC performance characterization to analyze compute intensive applications, memory access, and vectorization
• I/O analysis to analyze disk, network, and system bus throughput and latency
• micro-architecture exploration to identify processor instruction execution pipeline bottlenecks
• memory consumption and access analysis
• GPU offload analysis.
You can add your own application specific data points and inject them into the VTune Profiler results view. You can then interact with it the same way you are accustomed to.
Examples we will cover include:
• generating the timestamp for each data line in the custom data file using time and get system time calls.
• implementation of writing the discrete data types instantaneous value and count rate to the custom data file.
• using the system and VTune Profiler environment variables to format the full path name to the custom data file for this collection instance.
• Integrating custom data has been collected by other profiling techniques.
