Intel® MKL Cluster Support for IA-32 is now Deprecated

Published: 10/14/2014, Last Updated: 10/14/2014

Title:32 bit Support in Intel® Math Kernel Library (Intel MKL) for Clusters was now deprecated in Intel MKL 11.2 and support will be removed starting Intel MKL 11.3 Release.

Reason:Intel MKL is aligned with Intel MPI 5.0 which supports only 64 bit. Majority of customer base already selected Intel 64 as main development platform

Impact:Customers of Intel MKL for Clusters will have to go for 64 bit as 32 bit support is now deprecated.


  • Higher performance with richer registers/instructions set on Intel 64
  • Removing 4Gb memory limitation on input sizes to up to one terabyte (TB) of platform address space

Product and Performance Information


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.
