Overview
Intel® Trace Analyzer and Collector is a powerful tool for analyzing MPI applications, which essentially consists of two parts:
- Intel® Trace Collector is a low-overhead tracing library that performs event-based tracing in applications at runtime. It collects data about the application MPI and serial or OpenMP* regions, and can trace custom set functions. The product is completely thread safe and integrates with C/C++, FORTRAN and multithreaded processes with and without MPI. Additionally it can check for MPI programming and system errors.
- Intel® Trace Analyzer is a GUI-based tool that provides a convenient way to monitor application activities gathered by the Intel Trace Collector. You can view the desired level of detail, quickly identify performance hotspots and bottlenecks, and analyze their causes.

Known Issues and Limitations
- Tracing of MPI applications, which include the
MPI_Comm_spawnfunction calls, is not supported. - Intel® Trace Analyzer may get into an undefined state if too many files are opened at the same time.
- In some cases symbols information may appear incorrectly in the Intel® Trace Analyzer if you discarded symbols information from object files.
- MPI Correctness Checking is available with the Intel® MPI Library only.
