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

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
