BLAS and LAPACK: Difference between revisions

Although we recommend using FlexiBLAS, it is still possible to use Intel MKL directly. If you are using one of the Intel compilers (e.g. <code>ifort, icc, icpc</code>) then the solution is to replace <tt>-lblas</tt> and <tt>-llapack</tt> with <tt>-mkl=sequential</tt> (without internal MKL threading) or <tt>-mkl</tt> (with threading) in your compiler and linker options in order to ensure that the MKL and thus BLAS/LAPACK are used. See [https://software.intel.com/en-us/mkl-linux-developer-guide-using-the-mkl-compiler-option here] for more on the significance of <code>sequential</code> and other options.
