Package: intel-mkl Version: 2019.2.187-1 Severity: normal Tags: upstream Dear Maintainer,
Hi there! I was testing MKL's LAPACK routines as an alternative to ATLAS and found regression test failures. The apparently worst issue was that the complex SVD of 2x2 matrix ((1 0) (0 -2i)) gives singular values (0 1) rather than (2 1), which is badly wrong. I've discussed this on the Intel forum and it turns out that, although not obviously in their bug fix list, this is fixed in 2019u5. The CPU is a Xeon W-2156.
