Streaming SIMD Extensions (SSE) vector loops, and why vectorization is inhibited on non-vector loops -- Loops auto-parallelized for multi-core, and why parallelization is inhibited on serial loops -- Loops that are candidates for OpenMP parallelization -- Compute intensity of loops, and candidates for offloading to a GPU (Graphics Processing Unit) or accelerator -- Loops with very small or very large iteration counts, and how they can be modified to maximize performance for SSE and the cache-based memory hierarchy -- Data prefetching, and opportunities for prefetch tuning using directives and pragmas
