In the column picture, (C), the multiplication of the matrix A by the vector ~x produces a linear combination of the columns of the matrix: y = Ax = x1A[:,1] + x2A[:,2], where A[:,1] and A[:,2] are the first and second columns of the matrix A. In the row picture,...

What about "medium-sized" matrix multiplication?A more recent addition are GEMM routines which are parallelized using OpenMP (libxsmm_?gemm_omp). These routines leverage the same specialized kernel routines as the small matrix multiplications, in-memory code generation (JIT), and automatic code/par...
