Intel MKL 11.3 has introduced Intel TBB support.
This document contains instructions for linking to Intel MKL BLAS and LAPACK functions when building the PETSc libraries.
This article shows how to apply the permutation stored in array of indexes to a matrix. And also how to reconstruct the full permutation matrix.
Intel® MKL 10.3 extends MKL C support, add C interface for LAPACK.
