@rmuir Testing with the latest vector bench, commit 8f25834, I see: Linux - AVX 512 ``` Benchmark (size) Mode Cnt Score Error Units BinaryDotProductBenchmark.dotProductNew 1024 thrpt 5 16.467 ± 0.033 ops/us BinaryDotProductBenchmark.dotProductNewNew 1024 thrpt 5 20.941 ± 0.020 ops/us BinaryDotProductBenchmark.dotProductOld 1024 thrpt 5 3.251 ± 0.060 ops/us ``` And hardcoding a variant of ByteVector.SPECIES_128 -> ShortVector.SPECIES_256 -> IntVector.SPECIES_512, gives around ~20 ops/us on my machine, so this more general for >=256 is very good. -- This is an automated message from the Apache Git Service.
