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.

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.
