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*
  • Fortran
  • Advanced

  • Intel® AVX2
  • PARDISO
  • zgetrf/zgetri cannot invert matrix

    Using code that worked with previous versions (Intel 12.1 OpenMPI 1.4.4 MKL 10.2.5.035 on CentOS 6) of MKL, zgetrf/zgetri cannot invert a matrix that it previously inverted.

    Could the newer intel modules be changing how the arguments are accepted for lapack functions?

    The pivot index is determined by the output of zgetrf( .. , ipvt , ..) which is then fed into zgetri as input similarly. I believe this is the way to do it.
