I pushed changes to github.com/rmuir/vectorbench, too Results on my skylake with ` java -XX:UseAVX=0 -jar target/vectorbench.jar -p size=1024` look clean now. no crazy slowdowns for the integer math. consistent with what i see spinning up a QEMU, just easier to test yourself. ``` Benchmark (size) Mode Cnt Score Error Units BinaryCosineBenchmark.cosineDistanceNew 1024 thrpt 5 0.791 ± 0.014 ops/us BinaryCosineBenchmark.cosineDistanceOld 1024 thrpt 5 0.802 ± 0.014 ops/us BinaryDotProductBenchmark.dotProductNew 1024 thrpt 5 1.974 ± 0.028 ops/us BinaryDotProductBenchmark.dotProductOld 1024 thrpt 5 1.811 ± 0.440 ops/us BinarySquareBenchmark.squareDistanceNew 1024 thrpt 5 1.596 ± 0.043 ops/us BinarySquareBenchmark.squareDistanceOld 1024 thrpt 5 1.604 ± 0.022 ops/us FloatCosineBenchmark.cosineNew 1024 thrpt 5 3.457 ± 0.028 ops/us FloatCosineBenchmark.cosineOld 1024 thrpt 5 0.717 ± 0.009 ops/us FloatDotProductBenchmark.dotProductNew 1024 thrpt 5 8.613 ± 0.388 ops/us FloatDotProductBenchmark.dotProductOld 1024 thrpt 5 1.969 ± 0.324 ops/us FloatSquareBenchmark.squareNew 1024 thrpt 5 6.515 ± 0.147 ops/us FloatSquareBenchmark.squareOld 1024 thrpt 5 1.485 ± 0.015 ops/us ``` -- This is an automated message from the Apache Git Service.
