via HtP - developerWorks : Open source : The Jikes Research Virtual Machine

The Jikes Research Virtual Machine (RVM) is designed to execute Javaª programs that are typically used in research on fundamental virtual machine design issues. It will provide academic and research communities with a flexible testbed to prototype new virtual machine technologies and experiment with different design alternatives. It runs on the AIXª/PowerPCª, Linux©/PowerPC, and Linux/IA-32 platforms, and exhibits industry-strength performance for many benchmark programs on the first two of these platforms. The Jikes RVM includes the latest VM technologies for dynamic compilation, adaptive optimization, garbage collection, thread scheduling, and synchronization. The Jikes RVM is implemented in the Java programming language.
