A new project initiated by IBM to create a toolkit for language runtimes is about to go open source, and it could be used to speed up the performance of existing runtimes for many languages.
The OMR project takes pieces of IBM's J9 Java virtual machine, decouples them from Java, and turns them into components that can be added to any other language runtime. What's more, proof-of-concept implementations for Ruby and Python are already in the works, with the Ruby variant set to be open-sourced shortly.
According to a presentation given by Mark Stoodley, senior software developer at IBM Canada, at the 2015 JVM Language Summit, the reusable components include items that are often difficult to implement in any one language runtime -- for example, a JIT compiler that can provide a major boost to a language runtime's performance.
