I couldn't find any information on what LAPACK version is used with the current MKL version (2019 update 5).
In Matlab R2019a for example, I can see with the command "version('-lapack')" that MKL version 2018.0.3 with LAPACK 3.7.0 is used.
Is there a way to find out or look up the LAPACK version in the current and previous builds of MKL?
Robert, could you look at MKL 2019 Release Notes - https://software.intel.com/en-us/articles/intel-math-kernel-library-release-notes-and-new-features
Aligned MKL LAPACK functionality with Netlib LAPACK 3.7.1 and 3.8.0:Added routines for symmetric indefinite matrix factorization using a 2-stage Aasen’s algorithm.
yes, the current version of mkl ( 2019 u5) returns the wrong version of lapack, namely - 3.7.0. The issue is escalated and will keep this thread updated as soon as the problem will be fixed.
The problem has been fixed in MKL v.2020.1 which is available for download.
here is the ilaev output
