Stefan Marr, Researcher and Lecturer

Stefan Marr I am working at the School of Computing at the University of Kent. My work focuses on programming language implementation techniques and concurrent and parallel programming.

In my dissertation, I proposed an ownership-based metaobject protocol as a unifying substrate for concurrency support in multi-language VMs.

Currently, I am working on combining concurrency models in a safe manner and to enable developers to make sense of complex concurrent programs with appropriate tools.

Apr 9, 2019 Another Decade of SOM Language Implementation
SOM, the Simple Object Machine, is a little dynamic language designed for teaching object-oriented virtual machine design. It originates in Aarhus, Denmark, and according to Lars Bak, it was implemented in the course of two days by Kasper Lund. They used it back in 2001 for a course at the University of Aarhus.
Feb 1, 2014 How to get a JIT Compiler for Free: Implementing SOM Smalltalk with RPython and Truffle
Today at FOSDEM, I gave a brief talk on implementing SOM, a little Smalltalk, with RPython and Truffle. RPython, probably best known for the PyPy implementation, uses meta-tracing JIT compilation to make simple interpreters fast. Truffle, a research project of Oracle Lab, is an approach for building self-optimizing interpreters and in combination with Graal, it gives a JIT compiler for AST-like interpreters. In the talk, I briefly sketch both of them, without going into many details.
Feb 5, 2012 FOSDEM Smalltalk Dev Room: Sly and the RoarVM
Today, FOSDEM featured that first incarnation of a Smalltalk developer room. Unfortunately, FOSDEM is always packed with interesting talks, so, I only managed to attend a couple of talks. Most notably the talk on Spoon.
May 25, 2010 Locality and Encapsulation: My Student’s Presentation at the TiC Summer School
On the first day here at the summer school, the organizers gave us the opportunity to present our research ideas to the lecturers and other participants.
