Overview
========
When you use Intel analyzer tools to improve the performance of your software
application, during execution, use the Intel® Instrumentation and Tracing
Technology (ITT) and Just-In-Time (JIT) APIs to instrument your code to generate
trace data and control its collection. You use the ITT/JIT APIs to identify and
measure specific areas of code to get insights into performance bottlenecks and
resource utilization.
Components
----------
- **ITT API**: Powers your application to generate and control the collection
of trace data during its execution, seamlessly integrating with Intel tools.
- **JIT API**: Reports detailed information about just-in-time (JIT) compiled
code, enabling you to profile the performance of dynamically generated code.
Architecture
------------
The ITT/JIT APIs consist of two parts:
- **Static Part**: An open-source static library
(`ittapi <https://github.com/intel/ittapi>`__) that you compile and link
with your application to enable tracing features.
- **Dynamic Part**: A tool-specific shared library that collects and writes
trace data. You can find the reference implementation of the dynamic part
as a *Reference Collector* `here <ref_collector.html>`__.
