Threading infrastructure for the ActionScript Virtual Machine (Tamarin) — A foundational project that provides a cross-platform implementation of low-level threading library, high-level concurrency abstractions, and a thread safepointing infrastructure co-designed for Tamarin and Flash Player.

Simon Wilkinson
Researcher
I have a wide range of interests within programming language implementation, including concurrency, runtime compilation, garbage collection, meta-circularity, reflective architectures and meta-level architectures. My current focus is Adobe's managed runtimes and their exploitation of multi-core processors.
Projects |
Thread-safe asymmetric GC — An extension of Tamarin's garbage collection system to provide transparent support for multiple mutator threads. The mutator support is made asymmetric by design, where performance is biased to a distinguished thread per GC instance (typically this thread will be an ActionScript executing thread).
Multi-threaded dynamic background compiler — This project attempts to re-purpose Tamarin's existing foreground JIT components into a multi-threaded, deferred (hot-spotting), background compiler for ActionScript byte-code (ABC).
