To learn more about Conditional Bitwise Reproducibility (CBWR) see the following resources:

All of Intel MKL supports this new capability except the following: ScaLAPACK, cluster FFTs, data fitting functions, summary statistics functions, and the vsRngBeta random number generator on 32-bit operating systems.

If you've not already received a link to register for this beta you may register here.Intel® MKL 11.0 beta update 1 is now available.
  • Conditional Bitwise Reproducibility (CBWR): New functionality in Intel MKL now allows you to balance performance with reproducible results by allowing greater flexibility in code branch choice and by ensuring algorithms are deterministic. See the Intel® MKL User's Guide, listen to the webinar, or visit this CBWR article for more information. All of Intel MKL supports this new capability except the following: ScaLAPACK, cluster FFTs, data fitting functions, summary statistics functions, and the vsRngBeta random number generator on 32-bit operating systems.

  • Intel MKL also introduces optimizations using the new Intel® Advanced Vector Extensions 2 (AVX2) including the new FMA3 instructions. The following parts of Intel MKL have been optimized: BLAS, FFTs, Vector math functions, Data fitting functions, Random number generators, Summary statistics functions. Please refer Intel Haswell support in Intel MKL article for more details.

  • Other new Features
    • LAPACK: Introduced support for LAPACK version 3.4.0
    • VSL: Improved performance of viRngGeometric on Intel® Advanced Vector Extensions (AVX)
    • DFT: Increased performance of 1D real-to-complex DFT on Intel® Advanced Vector Extensions (AVX)
    • Removed support for Intel® Pentium® III processor. The minimal supported instruction set will be SSE2(Streaming SIMD Extensions 2)
    • FFT: Completed support for real-to-complex transforms with sizes given by 64-bit integers
    • Random number generators: Added support for a non-deterministic random number generator (VSL_BRNG_NONDETERM) based on the RdRand instruction

  • Documentation:
    • The Intel MKL Reference Manual in HTML format is no longer available with the product. (Download the latest MKL 11.0 Beta Update1 full HTML manual)
    • Man pages and Eclipse help integration are no longer provided



Please refer Intel® MKL: What's deprecated? article to see the details of functionalities deprecated in the Intel® MKL 11.0 Beta and Future Intel® MKL 11.0.

Intel® MKL is available as a stand-alone product and as a part of the Intel® Compiler Professional Edition. MKL 10.3 established a new directory hierarchy to simplify integration of the Intel MKL stand-alone products with the Intel Compiler Professional Editions.  Some changes in MKL 10.3 directory hierarchy include:

1)  The stand-alone Intel MKL product and Intel MKL product as a part of the Intel Compiler Professional Edition have the same directory hierarchy now.
2)  Directories formerly designated as "em64t" are now designated by the "intel64" tag. 
3)  Intel MKL dynamic libraries at Windows* are under "ComposerXE-2011\redist" directory. 
4)  Intel Compiler runtime libraries and OpenMP* libraries in Intel MKL are shared components with Intel Compilers. These files are under "ComposerXE-2011\compiler" directory.
5)  Intel MKL documentation is under "ComposerXE-2011\Documentation" directory.
6) There is no IA64 directory. Intel Itanium® architecture (IA-64) support is not included in this release.

The following picture shows a high-level directory structure of Intel MKL

The Intel® Math Kernel Library (Intel® MKL) is designed to run on multiple processors and operating systems. It is also compatible with several compilers and third party libraries, and provides different interfaces to the functionality. To support these different environments, tools, and interfaces Intel MKL provides mutliple libraries from which to choose.

To see what libraries are recommended for a particular use case, specify the parameters in the drop down lists below.





Note: For applications running on IA-32 with the Windows* operating system it is possible to use mkl_intel_s.lib instead of mkl_intel_c.lib (or mkl_intel_s_dll.lib instead of mkl_intel_c_dll.lib). This interface is compatible with the Compaq* Visual Fortran calling convention.

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.
