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 23, 2024: Why Are My Bytecode Interpreters Slow? Hunting Truffles with VTune

As part of our work on the AST vs. Bytecode Interpreters paper, I briefly looked at how the native code of ahead-of-time-compiled bytecode loops looks like, but except for finding much more code than what I expected, I didn’t look too closely at what was going on.
