Intel® VTune™ Amplifier XE and Intel® VTune™ Amplifier for Systems Help
This metric represents a fraction of cycles during which an application was stalled due to Core non-divider-related issues. For example, heavy data-dependency between nearby instructions, or a sequence of instructions that overloads specific ports. Hint: Loop Vectorization - most compilers feature auto-Vectorization options today - reduces pressure on the execution ports as multiple elements are calculated with same uop.
