How to use the Intel AVX in Java?

Question

How do I use the Intel AVX vector instruction set from Java? It\'s a simple question but the answer seems to be hard to find.

Answer 1

One option is to use Aparapi and install the Intel OpenCL driver. (Your code will be vectorized to work on both CPUs and GPUs, as long as an appropriate OpenCL driver is installed.)

Another option is to use JNI and call a C++ function that uses AVX intrinsics or was auto-vectorized by a compiler.
