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

Much of work revolves around making interpreters faster, detecting and preventing concurrency bugs at run time, and use modern language runtime systems to provide programmers with better tooling.

Feb 10, 2014: OMOP Ported to Opal on top of Pharo 3

To prepare some experiments with Pharo’s new compiler infrastructure and a simple AST interpreter, I ported my implementation of the Ownership-based Metaobject Protocol (OMOP) to the Pharo 3. Loading the OMOP into an image will give you an STM implementation, a basic actor system, communicating sequential processes, Clojure-like agents, and active objects. Eventually, the goal is to provide a more extensive set of such concurrent programming mechanisms on top of the OMOP, but for now these five should already give an impression of how the OMOP itself works.
