As far as I know the JVM will only auto-vectorize integers. Is there a way to tag a function such that you want floats vectorized too now? ART is a good point,

ART is a good point, compile on install lets you do this.

It also refers to floating point calculations. http://cr.openjdk.java.net/~vlivanov/talks/2017_Vectorization_in_HotSpot_JVM.pdf http://cr.openjdk.java.net/~vlivanov/talks/2017_Vectorizatio... https://software.intel.com/sites/default/files/managed/19/ae/JavaPerformanceWP.d46.pdf https://software.intel.com/sites/default/files/managed/19/ae... Also the Vector API development is ongoing and there is a talk at this week's Oracle ONE about the current state. ART no longer compiles on install since Android 7, that behaviour is specific to Android 5 and 6 versions. Since 7 it is a multistage runtime with hand written in Assembly interpreter, JIT + PGO, AOT + PGO on idle device. And as of 9, PGO data gets uploaded into the store and shared across devices on installation.
