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 6, 2010 Insertion Tree Phasers: Efficient and Scalable Barrier Synchronization for Fine-grained Parallelism
The last half year was an interesting departure from my actual PhD research. First, I though the idea of barriers and phasers might be interesting to incorporate into a virtual machine as part of my thesis, but as it turned out, they are much to high-level and are better off implemented in a library. The gain for direct support in a VM is just not proportional to the effort and restrictions which come with that step.
