#5 => Aysylu Greenberg on One VM to Rule Them All

In June, we have the pleasure of hearing Aysylu Greenberg, Software Engineer at Google and maintainer of the Clojure library Loom (https://github.com/aysylu/loom), speaking on the paper "One VM to Rule Them All" by Thomas Wuerthinger, Christian Wimmer, et al.

Paper

You can find the paper in the PWL repository (https://github.com/papers-we-love/papers-we-love/blob/bc15cfbe998b9dbde6c76480f9264e968e19155d/virtual_machines/README.md) and here (https://www.cs.purdue.edu/homes/gkrichar/papers/onward2013-wuerthinger-truffle.pdf).

Intro

The paper explains how you can write an interpreter and get an optimizing just-in-time (JIT) compiler for free. This enables language designers to focus on features without worrying about the complexities of compiler optimizations and code generation. This paper presents a Java Virtual Machine (JVM) that allows the application to control the JIT compiler behavior at runtime. We'll discuss how various programming languages can take advantage of this framework.

To intrigue compiler aficionados, the authors show how combining AST node rewriting during interpretation, optimization, and deoptimization produces high performance code from the interpreter without a language-specific compiler. In addition, they present how features of a variety of programming languages, such as JavaScript, Ruby, Python, R and others, map on the framework.

Bio

Aysylu Greenberg has many hobbies. By day, she works on search infrastructure at Google. For fun, she writes open-source libraries in Clojure, ponders the design of systems that deal with inaccuracies, paints and sculpts. Her curiosity for everything new and unexplored drives her to seek out cutting edge research papers. You can find @aysylu22 (https://twitter.com/aysylu22) on https://github.com/aysylu and http://aysy.lu.

Details

Doors open at 7 pm; the presentation will begin at 7:30 pm; and, yes, there will be beer and pizza.

After Aysylu presents the paper, we will open up the floor to discussion and questions.
