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.

Jan 2, 2021: Towards a Synthetic Benchmark to Assess VM Startup, Warmup, and Cold-Code Performance

One of the hard problems in language implementation research is benchmarking. Some people argue, we should benchmark only applications that actually matter to people. Though, this has various issues. Often, such applications are embedded in larger systems, and it’s hard to isolate the relevant parts. In many cases, these applications can also not be made available to other researchers. And, of course, things change over time, which means maintaining projects like DaCapo, Renaissance, or Jet Stream is a huge effort.
