Open Source Java Virtual Machine Software for Linux

X10 is a class-based, strongly-typed, garbage-collected, object-oriented language. To support concurrency and distribution, X10 uses the Asynchronous Partitioned Global Address Space programming model (APGAS). This model introduces two key concepts -- places and asynchronous tasks -- and a few mechanisms for coordination. With these, APGAS can express both regular and irregular parallelism, message-passing-style and active-message-style computations, fork-join and bulk-synchronous parallelism. Both its modern, type-safe sequential core and simple programming model for concurrency and distribution contribute to making X10 a high-productivity language in the HPC and Big Data spaces. User productivity is further enhanced by providing tools such as an Eclipse-based IDE (X10DT). Implementations of X10 are available for a wide variety of hardware and software platforms ranging from laptops, to commodity clusters, to supercomputers.

YABI93 is an Interpreter for the esoteric programming language Befunge, version "Befunge93". It is written in Java 1.5 and uses Swing for its graphical interface. YABI supports a multilanguage GUI.

The CodeTime platform covers every aspect of parallel software from authoring, through distribution, to run-time. Its goals are: high programmer productivity; write once, run high performance anywhere; and wide acceptance.

The grinj is a complete suite with compiler, VM and IDE for the language "grinj". it can be used as-is or as basis for your own compiler-VM-IDE-suite.

Fully graphical mips simulator, with a simple text editor. The aim is to not only have the entire mips isa implemented and simulated, but to have a mips ide. The text highlighting for the mips instructions set is currently underway. Version 3 Available.

Register machine which uses Sexp program files, has some debugging features and comes with a neat Swing GUI.
