Known Limitations: 

  • Intel MKL 11.3 Update 3 SGEMM and DGEMM functions on 64-bit Intel AVX2 and second generation of Intel® Xeon Phi™ Product Family may produce incorrect results when called from nested OpenMP regions. Workarounds include setting the environment variable, export OMP_NESTED=1, or calling the function, omp_set_nested(1),  before calling the SGEMM or DGEMM functions.
  • Intel MKL PARDISO produces incorrect results due to an issue with the nested dissection reordering algorithm (iparm[2]=2). To work around this issue, set iparm[2] = 0 to use the minimum degree algorithm for reordering.
