Intel(R) MPI Benchmarks provides a set of elementary benchmarks that conform to MPI-1, MPI-2, and MPI-3 standard. You can run all of the supported benchmarks, or a subset specified in the command line using one executable file. Use command-line parameters to specify various settings, such as time measurement, message lengths, and selection of communicators. For details, see the Intel(R) MPI Benchmarks User's Guide located in the /doc directory.
By default, Intel(R) MPI Benchmarks is installed at:
- C:\Program Files (x86)\IntelSWTools\imb on Windows* OS
- /opt/intel/imb on Linux* OS
Before using the Intel(R) MPI Benchmarks, please read the license agreements located in the imb/license directory.

- Product documentation is now available online only at: https://software.intel.com/en-us/imb-user-guide
- Removed support of the Intel(R) Xeon Phi(TM) coprocessors (formerly code named Knights Corner).
- Added a new option -imb_barrier.
- The PingPong and PingPing benchmarks are now equivalent to PingPongSpecificSource and PingPingSpecificSource, respectively. Their old behavior (with MPI_ANY_SOURCE) is available in PingPongAnySource and PingPingAnySource.
- Changed default values for the -sync and -root_shift options.
- Support for the Microsoft* Visual Studio* 2015. Microsoft* Visual Studio* 2010 support is removed.
- Bug fixes.
- Bug fixes.
- Introduced two new benchmarks: uniband and biband.
- Introduced two new command-line options for collective benchmarks: -sync and -root_shift.
- Fix of a bug where benchmarking was failing on certain message lengths with -DCHECK.
- Fix of a bug where benchmarking could continue after the time limit is exceeded.
- Introduced new components IMB-NBC and IMB-RMA that conform to the MPI-3.0 standard. Note: These components can only be built and used with MPI libraries that conform to the MPI-3 standard.
- Added new targets to the Linux* OS Makefiles:
- NBC for building IMB-NBC
- RMA for building IMB-RMA
- Updated Microsoft* Visual Studio* solutions to include the IMB-NBC and IMB-RMA targets.
- Consolidated all first-use documents in ReadMe_IMB.txt to improve usability.
- Introduced a new feature to set the appropriate algorithm for automatic calculation of iterations. The algorithm can be set through the -iter and -iter_policy options.
- Support for the Microsoft* Visual Studio* 2013. Microsoft* Visual Studio* 2008 support is removed.
You can get help on the Intel(R) MPI Benchmarks from the command line using the component name and the -help parameter. For example, for the IMB-MPI1 component, run: IMB-MPI1 -help
You can see the Intel(R) MPI Benchmarks User's Guide for details on the command-line parameters.
-
Set the CC variable to point to the appropriate compiler wrapper, mpiicc or mpicc.
-
Run one or more Makefile commands below:
make clean - remove legacy binary object files and executable files make MPI1 - build the executable file for the IMB-MPI1 component make EXT - build the executable file for one-sided communications benchmarks make IO - build the executable file for I/O benchmarks make NBC - build the executable file for IMB-NBC benchmarks make RMA - build the executable file for IMB-RMA benchmarks make all - build all executable files available
-
Run the benchmarks as follows:
mpirun -n <number_of_processes> IMB- [arguments]
where is one of the make targets above. For details, refer to the Intel(R) MPI Benchmarks User's Guide at: https://software.intel.com/en-us/imb-user-guide
Use the enclosed solution files located in the component-specific subdirectories under the imb/WINDOWS directory. Click on the respective ".vcproj" or ".vcxproj" project file and use the Microsoft* Visual Studio* menu to run the associated benchmark application.
-
Check that the Include, Lib, and Path environment variables are set as follows: %I_MPI_ROOT%\intel64\include %I_MPI_ROOT%\intel64\lib %I_MPI_ROOT%\mpi\intel64\bin The %I_MPI_ROOT% environment variable is set to the Intel(R) MPI Library installation directory.
-
Open the ".vcproj" or ".vcxproj" file for the component you would like to build. From the Visual Studio Project panel: a) Change the "Solution Platforms" dialog box to "x64". b) Change the "Solution Configurations" dialog box to "Release". c) Check other settings as required, for example: General > Project Defaults - Set "Character Set" to "Use Multi-Byte Character Set" C/C++ > General - Set "Additional Include Directories" to "$(I_MPI_ROOT)\intel64\include" - Set "Warning Level" to "Level 1 (/W1)" C/C++ > Preprocessor - For the "Preprocessor definitions" within the Visual Studio projects, add the conditional compilation macros WIN_IMB and _CRT_SECURE_NO_DEPRECATE. Depending on the components you intend to use, add one or more of the following macros: MPI1, EXT, MPIIO, NBC, RMA. Linker > Input - Set "Additional Dependencies" to "$(I_MPI_ROOT)\intel64\lib\impi.lib". Make sure to add quotes.
-
Use F7 or Build > Build Solution to create an executable.
