The Intel® VTune™ Profiler provides the ability to augment performance analysis types that include:

• Hot spot 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 use
• HPC performance characterization to analyze compute intensive applications, memory access, and vectorization
• I/O analysis for disk, network, and system bus throughput and latency
• Micro-architecture exploration to identify processor instruction for running pipeline bottlenecks
• Memory consumption and access analysis
• GPU offload analysis

You can add your own application-specific data points and then inject them into the Intel VTune Profiler results view. You can then interact with the data the same way you are accustomed to. Examples 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 Intel VTune Profiler environment variables to format the full path name to the custom data file for this collection instance
• Integrated custom data has been collected by other profiling techniques
