Intel® Trace Analyzer and Collector Release Notes for Linux* OS


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.

To receive technical support and updates, you need to register your product copy. See Technical Support below.

  • Correctness Checking: check for MPI and system errors at runtime (including distributed memory checking)
  • ROMIO*: extended support of MPI-2 standard parallel file I/O
  • Comparison feature: compare two trace files and/or two regions (in one or two trace files)
  • Command line interface for the Intel Trace Analyzer

System Requirements

Hardware Requirements

    • Intel® Core™ processor family
    • Intel® Xeon® E5 v4 processor family recommended
    • Intel® Xeon® E7 v3 processor family recommended
    • 2nd Generation Intel® Xeon Phi™ Processor (formerly code named Knights Landing)
  • 1 GB of RAM per core (2 GB recommended)
  • 1 GB of free hard disk space

Software Requirements

  • Operating systems:
    • Red Hat* Enterprise Linux* 6, 7
    • Fedora* 23, 24
    • CentOS* 6, 7
    • SUSE* Linux Enterprise Server* 11, 12
    • Ubuntu* LTS 14.04, 16.04
    • Debian* 7, 8
  • MPI implementations:
    • Intel® MPI Library 5.0 or newer
  • Compilers:
    • Intel® C++/Fortran Compiler 15.0 or newer (required for OpenMP* support)
    • GNU*: C, C++, Fortran 77 3.3 or newer, Fortran 95 4.4.0 or newer

Known Issues and Limitations

  • Static Intel® Trace Collector libraries require Intel® MPI Library 5.0 or newer.
  • Tracing of MPI applications, which include the MPI_Comm_spawn function 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.
  • Intel® Trace Analyzer requires libpng 1.2.x (, otherwise the Intel Trace Analyzer GUI cannot be started.
  • Intel® Trace Analyzer and Collector does not support Fortran applications or libraries compiled with the -nounderscore option. Only functions with one or two underscores at the end of the name are supported. See details on Fortran naming conventions at
