Intel® Math Kernel Library 2017 Update 4 is now available

Intel® Math Kernel Library (Intel® MKL) is a highly optimized, extensively threaded, and thread-safe library of mathematical functions for engineering, scientific, and financial applications that require maximum performance.

Announcing new tool -- Intel® Math Kernel Library LAPACK Function Finding Advisor

The Intel® Math Kernel Library (Intel® MKL) LAPACK domain contains a huge variety of routines. Now, a new tool is provided with a faster method of finding appropriate LAPACK functions in Intel® Math Kernel Library Developer Reference document. This tool would be very useful for Intel® MKL newbies and for users not familiar with LAPACK function naming conventions. By using this tool, users can specify functionality as parameters in drop down lists, descriptions of all functions satisfying the requirements will be shown through this tool.

  • PSSYGVX - LWORK parameter number 28 had an illegal value

    Dear Intel Forum,

     I am trying to use PSSYGVX, however if a use a matrix larger than 5000 everytime the function returns:

       PSSYGVX  parameter number   28 had an illegal value
       The info parameter is -28

    I tryed to use lwork = -1 (which i believe is the 28 parameter) to ask wich is the optimum value, even with this number a recive the same mensagem. Another values was tested without success. Please, this could be a memory issue ? There any way to debug this ?

     Best regards

    Performance test with Optimized LINPACK Benchmark

    Hi,

    I evaluated my embedded board, which has Xeon D 1.7GHz(8-cores, 12MB cache and 32GB DDR).
    The tool is Intel Optimized LINPACK Benchmark in MKL 2018.

    I expected about 400 GFLOPS but the result was about 145 GFLOPS. I would like to know the result is reasonable or not, and then how to get maximum performance.

    Thank you.
