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 fast dynamic language implementations, on combining concurrency models in a safe manner, automatically preventing concurrency issues from manifesting, and to enable developers to make sense of complex concurrent programs with appropriate tools.

For contact details see my page at the School of Computing.

Jul 11, 2019 SOMns 0.7.0 Release with Extension Modules and Artifacts
It has been a while since we put together a release for SOMns. And it has been even longer, since I last wrote about it on this blog.
May 27, 2019 Generating an Artifact From a Benchmarking Setup as Part of CI

Disclaimer: The artifact, for which I put this automation together, was rejected. I take this as a reminder that the technical bits still require good documentation to be useful.
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.
