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. 

Intel® MKL 11.3.3 patch

There are two listed below limitations with Intel® Math Kernel Library (Intel® MKL) 11.3 Update 3 which were discovered recently. The official fix of these issues will be available the nearest update Intel MKL 11.3.4.

If you require an immediate Intel MKL update to address these issues, please submit a ticket at Intel Premier Support (https://premier.intel.com) for the Intel MKL product.

Known Limitations: 

  • FreeBSD*
  • Linux*
  • Microsoft Windows* (XP, Vista, 7)
  • Microsoft Windows* 10
  • Microsoft Windows* 8.x
  • Unix*

  • Create N VSLStreamStatePtr affected other MKL function's performance

    At first I want to generate random in multythreads in the following code:

    #define nstreams 8
    VSLStreamStatePtr stream[nstreams];

    int k;
    for ( k=0; k< nstreams; k++ )
    {
    vslNewStream( &stream[k], VSL_BRNG_MT2203+k, seed );
    }

    But I found, If I generate 8 VSLStreamStatePtr , other MKL functions performance will be affected(5 times slower then normal), these affected funtions are:

    dtrsv("Lower", "No transpose", "Unit", ...);

    dgemv("No transpose", ...);

    dtrsm("Right", "Upper", "No transpose", "Nunit", ...);

    Intel® Math Kernel Library (Intel® MKL) and pkg-config tool

        The pkg-config tool[1] is a widely used tool that many users apply to their makefiles. Intel® Math Kernel Library (Intel® MKL) provides pkg-config metadata files for this tool starting with the Intel MKL 2018 Update 1 release.

        The Intel MKL pkg-config metadata files cover only the most popular Intel MKL configuration on 64-bit Linux/macOS/Windows operating systems for C.

    This table describes the Intel MKL pkg-config metadata files provided and the Intel MKL configurations that they cover.
