============================
Packing Blocks from Matrix A                                            [TOC]
============================

In the cache optimized GEMM-Operation $\beta C + \alpha A B \to C$ the matrix
$A$ gets partitioned into blocks with maximal dimension $M_c \times K_c$.  Each
block $A_{i,l}$ of $A$ gets packed into col-major horizontal panels with $M_r$
rows.
