Intel MKL has been optimized on Intel® Xeon 5500 series and Intel Core™ i7 processors.
 
The following functions have significant performance improvements for the above processors in Intel MKL 10.1 version

• BLAS : 
       o DGEMM
       o SGEMM, DTRSM (64 bit)

• VML : 
       o Asin, Asinh, Acos, Acosh, Atan, Atan2, Atanh, Cbrt, CIS, Cos, Cosh, Conj, Div, ErfInv, Exp, Hypot, Inv, InvCbrt,
          InvSqrt, Ln, Log10, MulByConj, Sin, SinCos, Sinh, Sqrt, Tanh.

• VSL : 
       o Uniform Random Number Generators 
       o VSL distribution generators based on Wichmann-Hill, Sobol, and Niederreiter BRNGs (64-bit only).

Intel MKL also has significant performance and efficiency improvements for Linpack benchmark on Intel® Xeon 5500 processors.

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.
