I had always believed the OpenJDK did based on this http://prestodb.rocks/code/simd/ http://prestodb.rocks/code/simd/ which was on HN a while ago https://news.ycombinator.com/item?id=14636802 https://news.ycombinator.com/item?id=14636802 so yes?
This is really out of my depth though, would love someone who actually knows this area to pipe in.
- xyzzy_plugh 7y agoNo, afaik this was not a default optimization. There are SIMD optimizations in specific paths but I'm not aware of general low level autovectorizations before this (outside of ORC/OIL which was never generally available for JVM afaik)
- zjaffee 7y agoSuperUser is enabled by default on openJDK, but it's incredibly simplistic vectorizations being done as can be seen in the article the person above posted.
