pyPEG is a quick and easy solution for creating a parser in Python programs. pyPEG uses a PEG language in Python data structures to parse, so it can be used dynamically to parse nearly every context free language. The output is a plain Python data structure called pyAST, or, as an alternative, XML.
Trad4 is a fully concurrent, thread safe, graph based programming language that scales linearly on multiple cores. It is initially intended for deployment in the financial industry to model real-time risk. Trad4 is proposed as an alternative to the Von Neumann model of computer architecture. It is a new way of arranging programs in memory and a new style of flow-of-control.
JSDAI is a toolkit around STEP or ISO 10303, the STandard for the Exchange of Product model data. It supports the Express data modelling language as defined in ISO 10303-11 and provides data exchange capabilities according to ISO 10303-21 STEP-file and ISO 10303-28 STEP-XML. JSDAI Runtime is an API according ISO 10303-22, the Standard Data Access Interface (SDAI) for the Java programming language, ISO 10303-27. JSDAI Developer is for the development of Express data models, including Express-G diagrams.
Aseba is an event-based architecture for distributed control of mobile robots. It targets integrated multi-processor robots or groups of single-processor units, real or simulated. The core of aseba is a lightweight virtual machine tiny enough to run even on microcontrollers. Robots are programmed in a user-friendly scripting language using a cozy integrated development environment.
AutoAbacus is a powerful equation solving library that finds solutions to equation sets. Equations are passed to AutoAbacus as text, and the program attempts to find a solution that satisfies all constraints. The equations can be linear or polynomial, and can include arbitrary functions. By profiling the types of equations in the system and their dependencies on each other, AutoAbacus uses appropriate solution methods to solve individual subsets of equations. Applications range from use in a business rules engine to solving engineering equation systems.
JDBCPersistence is an Object Relational Mapping framework. Designed for use in high volume online banking applications, the package delivers performance matching that exhibited by hand-written JDBC code. It uses a bytecode generation technique to create bytecode for classes that implement logic used for persisting the data. As the framework uses SQL for querying data, the learning curve is reduced. The footprint of the package is under 200KB.
X10 is a type-safe, modern, parallel, distributed object-oriented language intended to be very easily accessible to Java programmers. It is targeted to future low-end and high-end systems with nodes that are built out of multi-core SMP chips with non-uniform memory hierarchies, and interconnected in scalable cluster configurations. X10 highlights the explicit reification of locality in the form of places; lightweight activities embodied in async, future, foreach, and ateach constructs; constructs for termination detection and phased computation; the use of lock-free synchronization; and the manipulation of global arrays and data structures.
The RDVIS tool helps programmers pin-point the sources of cache misses and poor temporal locality in their source code. The visualization often directs the experienced programmer towards the necessary program transformations within a few minutes. The tool consists of two parts: a GUI that visualizes the low temporal locality patterns, and a patched GCC compiler to extract the low-locality patterns from programs.
