Installation Guide and Release Notes 31

7.1 Changes in This Version

7.1.1 What’s New in Intel MKL 11.2

 Intel MKL now provides optimizations for all Intel® Atom™ processors that support

Intel® Streaming SIMD Extensions 4.1 (Intel® SSE4.1) and Intel® Streaming SIMD

Extensions 4.2 (Intel® SSE4.2) instruction sets

 Introduced support for Intel® Advanced Vector Extensions 512 (Intel® AVX-512)

instruction set with limited optimizations in BLAS, DFT and VML

 Introduced Verbose support for BLAS and LAPACK domains, which enables users to

capture the input parameters to Intel MKL function calls

 Introduced support for Intel® MPI Library 5.0

 Introduced the Intel Math Kernel Library Cookbook (http://software.intel.com/en-

us/mkl_cookbook) , a new document that describes how to use Intel MKL routines to

solve certain complex problems

 Introduced the MKL_DIRECT_CALL or MKL_DIRECT_CALL_SEQ compilation feature

that provides ?GEMM small matrix performance improvements for all processors (see

the Intel® Math Kernel Library User's Guide for more details)

 Added the ability to link a Single Dynamic Library (mkl_rt) on Intel® Many Integrated

Core Architecture (Intel® MIC Architecture)

 Added a customizable error handler. See the Intel Math Kernel Library Reference

Manual description of mkl_set_exit_handler() for further details

 Extended the Intel® Xeon Phi™ coprocessor Automatic Offload feature with a resource

sharing mechanism.See the Intel Math Kernel Library Reference Manual for the

description of mkl_mic_set_resource_limit() function and the

MKL_MIC_RESOURCE_LIMIT environment variable for further details

 Parallel Direct Sparse Solver for Clusters:

o Introduced Parallel Direct Sparse Solver for Clusters, a distributed memory

version of Intel MKL PARDISO direct sparse solver

o Improved performance of the matrix gather step for distributed matrices

o Enabled reuse of reordering information on multiple factorization steps

o Added distributed CSR format, support of distributed matrices, RHS, and

distributed solutions

o Added support of solving of systems with multiple right hand sides

o Added cluster support of factorization and solving steps

o Added support for pure MPI mode and support for single OpenMP* thread in

hybrid configurations

 BLAS:

o Improved threaded performance of ?GEMM for all 64-bit architectures supporting

Intel® Advanced Vector Extensions 2 (Intel® AVX2)

o Optimized ?GEMM, ?TRSM, DTRMM for the Intel AVX-512 instruction set

o Improved performance of ?GEMM for outer product [large m, large n, small k]

and tall skinny matrices [large m, medium n, small k] on Intel MIC Architecture

o Improved performance of ?TRSM and ?SYMM in Automatic Offload mode on

Intel MIC Architecture
