To prevent any surprises, I backported the branch and also the benchmark module to 9.x and ran everything with Java 11.0.13 (on my Intel Laptop): ``` branch_9x (Java 11.0.13), Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz, 1992 MHz Benchmark (size) Mode Cnt Score Error Units VectorUtilBenchmark.floatCosineScalar 1024 thrpt 5 0,827 ± 0,021 ops/us VectorUtilBenchmark.floatDotProductScalar 1024 thrpt 5 2,293 ± 0,070 ops/us VectorUtilBenchmark.floatSquareScalar 1024 thrpt 5 1,443 ± 0,057 ops/us Robert backported Java 11, Intel(R) Core(TM) i7-8565U CPU @ 1.80GHz, 1992 MHz Benchmark (size) Mode Cnt Score Error Units VectorUtilBenchmark.floatCosineScalar 1024 thrpt 5 1,646 ± 0,216 ops/us VectorUtilBenchmark.floatDotProductScalar 1024 thrpt 5 3,189 ± 0,221 ops/us VectorUtilBenchmark.floatSquareScalar 1024 thrpt 5 2,716 ± 0,098 ops/us ``` In conclusion, no surprises with Hotspot of Java 11, so it is safe to backport this branch and have scalar mode also improved between 1 and 2 times. The direction if we enable FMA on AMD or not is still to be discussed. -- This is an automated message from the Apache Git Service.
