About:
ITTAPI provides a C/C++ library and Python bindings for Intel's Instrumentation and Tracing Technology (ITT) and Just-In-Time (JIT) API. It enables developers to annotate their applications with markers and domains, allowing performance analysis tools like Intel VTune Profiler to visualize and analyze application behavior. This is essential for identifying bottlenecks in complex, dynamically compiled code such as JIT-based runtimes.
Key Features:
  • C/C++ and Python API for Intel VTune Profiler integration
  • Support for marking JIT-compiled code regions
  • APIs for defining tasks, counters, and event markers
  • Cross-platform support (Windows, Linux, macOS)
Use Cases:
  • Profiling JIT-compiled languages like Java, JavaScript, or Python
  • Annotating high-performance computing (HPC) applications for deeper analysis
  • Identifying performance bottlenecks in dynamically generated code
Alternatives:
  • Intel VTune Profiler – VTune is the analysis tool that consumes ITTAPI data; ITTAPI is the instrumentation library used to generate that data.
  • Perf (Linux) – Perf is a system-wide profiler that samples hardware events, whereas ITTAPI provides explicit, user-defined annotations for logical regions.
