SIMD is not Intel only. ARM has SIMD support. So does AMD. Portability is not a problem. The C/C++ compilers have nice wrappers on them to let JVM take advantage of them. And there’s always the non-simd version to fall back to. JVM is the correct abstraction layer to implement this for portability. Any Java program doing sorting benefited from this on all supported platforms.
