Tail handling is not a problem if you generate custom SIMD code for your particular computation. For example, https://NN-512.com https://NN-512.com (but you can imagine similar code generators for other domains) Vector overhang (masking), unrolling, full/partial iterations are all known when the code is generated. This allows a very tight fit between the SIMD processor and the work that needs to be done.
