control: tags -1 +wontfix Hi Ido,
As discussed in [1], I think this issue is not fixable because there is no bug in either MKL or Octave. The GEMM computation error is just because the clash between libgomp and libiomp. If you need to use Octave against MKL, please set the environment variable to switch threading model to GNU OpenMP or TBB: MKL_THREADING_LAYER=gnu MKL_THREADING_LAYER=tbb Please don't set it as MKL_THREADING_LAYER=intel, which could cause the original problem you described.
