HI all: I have investigate some vector friendly java codes's jit assembly code by the JITWatch tool . Then I found that JVM did not generate the expected AVX code.According to some conclusion from the JVM expert , JVM only supply some restrict usage case to generate AVX code.
I found Intel have fired a project called panama, which supply the intrinsic vector API to actual execute AVX code. Here is the reference ( https://software.intel.com/en-us/articles/vector-api-developer-program-for-java) . It also supports offheap calculation. From our JVM team's message, the vector api will be released at JDK11. So I wonder whether we can distribute Intel's current JVM as a supplied default JVM to users (like spark distribution with a default scala) and as a option to rewrite parts of our operator codes according to this new vector api.
