Apache Harmony is the Java SE project of the Apache Software Foundation. The aim of the project is to produce a large and healthy community of those interested in runtime platforms tasked with ... [More] creation of: - a compatible, independent implementation of Java SE under the Apache License v2 - a community-developed modular runtime (VM and class library) architecture. [Less]

Jikes RVM (Research Virtual Machine) provides a flexible open testbed to prototype virtual machine technologies and experiment with a large variety of design alternatives. The system is licensed under ... [More] an OSI approved license. Jikes RVM runs on many platforms and advances the state-of-the-art of virtual machine technologies for dynamic compilation, adaptive optimization, garbage collection, thread scheduling, and synchronization. A distinguishing characteristic of Jikes RVM is that it is implemented in the Java™ programming language and is self-hosted i.e., its Java code runs on itself without requiring a second virtual machine. Most other virtual machines for the Java platform are written in native code (typically, C or C++). A Java implementation provides ease of portability, and a seamless integration of virtual machine and application resources such as objects, threads, and operating-system interfaces. [Less]

SP-Forth is a Forth compiler, developed in Russia, and the basis for some other open source work. It is not 'Mostly written in Perl' (this is a bug of Ohloh :). It written in FORTH.

Nexgent is a nagios like daemon that runs on paravirtualized Xen guests. Vital information such as loads, iowait, memory usage and disk usage are exported to the privileged domain via Xenbus. The ... [More] privileged domain can then establish inotify like watches on guest values, enabling the privileged domain to take action on events (such as loads getting too high, memory being exhausted or a disk filling up). This program is not yet release quality, but soon will be. [Less]

Open source binary translator using advanced JIT, adaptive and optimizing compiler techniques.

Welcome to the Metacircular Research Platform (MRP), a new design effort in building performant multipurpose metacircular systems. Metacircularity is a property whereby a system and its run-time are ... [More] all written in the same programming language. MRP is written in Java, including libraries, compilers, garbage collectors and binary translators. It is also a test bed for operating systems written in a metacircular manner. [Less]
