Joeq is a virtual machine and compiler infrastructure
designed to facilitate research in virtual machine technologies such
as Just-In-Time and Ahead-Of-Time compilation, advanced garbage
collection techniques, distributed computation, sophisticated
scheduling algorithms, and advanced run time techniques. Joeq is
entirely implemented in Java, leading to reliability, portability,
maintainability, and efficiency. It is also language-independent, so
code from any supported language can be seamlessly compiled, linked,
and executed --- all dynamically. Each component of the virtual
machine is written to be independent with a general but well-defined
interface, making it easy to experiment with new ideas. Joeq is
released as open source software, and is being used as a framework by
researchers on five continents on topics ranging from automatic
distributed virtual machines to whole-program pointer analysis.
