It's very common in image and audio processing algorithms, and overall lots of general-purpose libraries used in software will use SIMD instruction sets. Even things like memcpy or String.IndexOf are vectorized in modern runtimes. IIRC Facebook released a very carefully tuned hashmap that uses SIMD instructions to do many of its search operations.
