Title: Bringing the Code to the Data with GraalVM



High-performance language runtimes often execute isolated from datastores. Encoding logic in the form of stored procedures requires relying on different execution engines and sometimes even different languages. Our vision of the future of execution runtimes is GraalVM: an integrated, polyglot, high-performance execution environment that can not only run stand-alone but also efficiently embedded in other systems. It supports shared tooling independent of the specific language and specific embedding. We designed the GraalVM runtime with complete separation of logical and physical data layout in mind. This allows direct access to custom data formats without marshalling overheads. GraalVM supports dynamic languages such as JavaScript, Ruby, Python and R. Additionally, even lower level languages such as C, C++, Go, and Rust are integrated into the ecosystem via LLVM bitcode and can execute in a sandboxed and secure manner. We believe this language-level virtualisation will provide major benefits for system performance and developer productivity.


Thomas Wuerthinger is researcher at Oracle Labs Switzerland. His research interests include Virtual Machines, Feedback-directed Runtime Optimizations, and Static Program Analysis. His current focus is the Graal project that aims at developing a new dynamic compiler for Java. Additionally, he is the architect of the Truffle self-optimizing runtime system, which uses partial evaluation for automatically deriving high-performance compiled code from AST interpreters. Before joining Oracle Labs, he has worked on the IdealGraphVisualizer, the Crankshaft/V8 optimizing compiler, and the Dynamic Code Evolution VM. He received a PhD degree from the Johannes Kepler University Linz.
