Changes in Intel® MPI Benchmarks 3.2.1

This release includes the following updates as compared to the Intel® MPI Benchmarks 3.2:

Changes in Intel® MPI Benchmarks 3.2

Intel® MPI Benchmarks 3.2 has the following changes as compared to the previous version:

Run Time Control by Default

The improved run time control that is associated with the –time flag. This is the default value for the Intel® MPI Benchmarks executable files (with a maximum run time per sample set to 10 seconds by the SECS_PER_SAMPLE parameter in the include file IMB_settings.h).

Makefiles

The nmake files for Windows* OS were removed and replaced by Microsoft* Visual Studio* solutions.

The Linux* OS Makefiles received new targets:

Microsoft* Visual Studio* Project Folders

Intel® MPI Benchmarks 3.2 contains Microsoft* Visual Studio* solutions based on an installation of the Intel® MPI Library. A dedicated folder is created for the Microsoft* Windows* OS without duplicating source files. The solutions refer to the source files that are located at their standard location within the Intel® MPI Benchmarks directory structure.

As such solutions are highly version-dependent, see the information in the corresponding ReadMe.txt files that unpack with the folder. You are recommended to learn about the Microsoft* Visual Studio* philosophy and the run time environment of your Windows cluster.

Changes in Intel® MPI Benchmarks 3.1

This release includes the following updates as compared to the Intel® MPI Benchmarks 3.0:

Miscellaneous Changes

In the Exchange benchmark, the two buffers sent by MPI_Isend are separate. The command line is repeated in the output. Memory management is completely encapsulated in the functions IMB_v_alloc/IMB_v_free.

Changes in Intel® MPI Benchmarks 3.0

This release includes the following updates as compared to the Intel® MPI Benchmarks 2.3:

Optimization Notice

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
