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)\Intel\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.

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

- Thread safety support in the MPI initialization phase
Intel(R) MPI Benchmarks 3.2 Update 2 is an update release of Intel(R) MPI Benchmarks 3.2 Update 1.
- Support for large buffers greater than 2 GB for some MPI benchmarks
- New benchmarks PingPongSpecificSource and PingPingSpecificSource. The exact destination rank is used for these tests instead of MPI_ANY_SOURCE as in PingPong and PingPing tests. Use the include option to enable new benchmarks. For instance, include PingPongSpecificSource PingPingSpecificSource
- New options -include/-exclude to better control benchmarks list
Compared to Intel(R) MPI Benchmanrks 3.2, Intel(R) MPI Benchmarks 3.2.1 includes the following updates:
- Fix of memory corruption when the -msglen command-line option is used with the Intel(R) MPI Benchmark executables
- Fix in Accumulate benchmark related to using the CHECK conditional compilation macro
- Fix for integer overflow in dynamic calculations on the number of iterations
- Recipes for building IA-32 executables within Microsoft* Visual Studio* 2005 and Microsoft* Visual Studio* 2008 project folders associated with the Intel(R) MPI Benchmarks
Compared to its predecessors, Intel(R) MPI Benchmarks 3.2 has one other default setting:
-Run time control
Intel(R) MPI Benchmarks dynamically computes a repetition count for each experiment so that the sum of the resulting repetitions (roughly) does not exceed a given run time. The run time for each sample (= 1 message size with repetitions) is set in => IMB_settings.h, IMB_settings_io.h (current value: 10 seconds, preprocessor variable SECS_PER_SAMPLE)
To override this behavior, use the flag -time
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.
Building Instructions for Linux* OS for Intel(R) Many Integrated Core Architecture (Intel MIC Architecture)
To build Intel(R) MPI Benchmarks for Linux* OS for Intel(R) Many Integrated Core Architecture (Intel(R) MIC Architecture), follow these steps:
-
Build the Intel MPI Benchmarks for the host system: host$ source /composerxe_mic/bin/compilervars.sh intel64 host$ source /intel64/bin/mpivars.sh host$ cd /src host$ make -f make_ict
-
Build the Intel MPI Benchmarks for the target system with the Intel(R) MIC Architecture. Note that the corresponding make_ict_mic makefile uses the -mmic option that may be specific to Intel(R) compilers. host$ source /composerxe_mic/bin/compilervars.sh intel64 host$ source /intel64/bin/mpivars.sh host$ cd /src host$ make -f make_ict_mic
For details on running the resulting executable files, see the Intel(R) MPI Library documentation.
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. The default installation directory is C:\Program Files (x86)\Intel\mpi<version>, where is the product version.
-
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.
- Change the Include, Lib, and Path environment variables to the following settings, respectively:
%I_MPI_ROOT%\ia32\include %I_MPI_ROOT%\ia32\lib %I_MPI_ROOT%\ia32\bin
The %I_MPI_ROOT% environment variable is set to the Intel(R) MPI Library installation directory. The default installation directory is C:\Program Files (x86)\Intel\mpi<version>, where is the product version. 2)Open the relevant Visual Studio 2010*, Visual Studio 2012*, or Visual Studio 2013* projects under the WINDOWS subfolder for Intel(R) MPI Benchmarks. From the Visual Studio Project panel: a) Change the "Solution Platforms" dialog box to "Win32". b) Change the "Solution Configurations" dialog box to "Release". c) Check other settings in the usual style, for example General > Project Defaults - Set "Character Set" to "Use Multi-Byte Character Set" C/C++ > General - Set "Additional Include Directories" to "$(I_MPI_ROOT)\ia32\include". - Set "Warning Level" to "Level 1 (/W1)" C/C++ > Preprocessor - For the "Preprocessor definitions" within the Visual Studio projects, add the conditional compilation macros WIN_IMB and _CRT_SECURE_NO_DEPRECATE. Depending on the components you intend to use, add one or more of the following macros: MPI1, EXT, MPIIO, NBC, RMA. Linker > Input Set "Additional Dependencies" to "$(I_MPI_ROOT)\ia32\lib\impi.lib". Make sure to add quotes.
- Use F7 or Build > Build Solution to create an executable.
