What is Polyglot Native?

Video overview of an ahead-of-time compiler for Java bytecode combined with a low-footprint VM

Execution of JVM-based programs uses bytecode loading and interpretation, just-in-time compilation, and monolithic heaps causes JVM-based programs to start-up slowly with a high memory footprint. In recent years, different projects were developed to address these issues:
ahead-of-time compilation for the JVM (JEP 295) improves on JVM startup time while Scala Native and Kotlin/Native provide language-specific solutions by compiling code with LLVM and providing language-specific runtimes.

Now Polyglot Native is presented an ahead-of-time compiler for Java bytecode combined with a low-footprint VM. With Polyglot Native, programs written in Kotlin, Scala, and other JVM-based languages have minimal startup time as they are compiled to native executables. Footprint of compiled programs is minimized by using a chunked heap and reducingnecessary program metadata.

In this talk, you will see:

  • the architecture of Polyglot Native and compare it to existing projects.
  • live-demo of a project that compiles code from Kotlin, Scala, Java, and C into a single binary executable.
  • intricacies of interoperability between Polyglot Native and C.

JDK 9 Hidden Gems

Mikael Vidstedt and Sandhya Viswanathan talk about JDK 9 optimizations spanning support for larger vectors
01 November

What does JDK 9 mean to you? Modularization is the first thing that comes to mind, but there is a lot more. Come discover less-well-known but important technologies that Oracle has been working on with partners such as Intel to provide a higher-performance, lower-footprint, scalable Java with JDK 9.

This session talks about JDK 9 optimizations spanning support for larger vectors with enhanced vectorization, optimized math libraries, cryptography and compression acceleration, compact strings, new APIs with associated optimized implementation, and many more features that help big data, cloud, microservices, HPC, and FSI applications.

Speakers are:

  • Mikael Vidstedt, JVM Architect, Oracle
  • Sandhya Viswanathan, Senior Staff Software Engineer, Intel Corporation
