API Support

Intel® VTune™
Profiler
supports two kinds of APIs:
  • The instrumentation and tracing technology (ITT) APIs provided by the
    Intel®
    VTune™
    Profiler
    enable your application to generate and control the collection of trace data during its execution.
  • The JIT (Just-In-Time) Profiling API provides functionality to report information about just-in-time generated code that can be used by performance tools. You need to insert JIT Profiling API calls in the code generator to report information before JIT-compiled code goes to execution. This information is collected at runtime and used by tools like
    Intel® VTune™
    Profiler
    to display performance metrics associated with JIT-compiled code.
