    X10

    Performance and Productivity at Scale

    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.

    GroIMP

    Growth-grammar related Interactive Modelling Platform

    Important: Groimp migrates to Gitlab. You can find the latest code at "https://gitlab.com/grogra/groimp/". The version on Sourceforge will not be updated anymore. The modelling platform GroIMP is designed as an integrated platform which incorporates modelling, visualisation and interaction. It exhibits several features which makes itself suitable for the field of biological or ALife modelling: The “modelling backbone” consists in the language XL. It is fully integrated, e.g., the user can interactively select the rules to be applied. GroIMP provides classes that can be used in modelling: Turtle commands, further geometrical classes like bicubic surfaces, the class Cell which has been used in the Game Of Life implementation, and so on. The outcome of a model is visualised within GroIMP. In the visual representation of the model output, users can i

    PEARL Compiler and Runtime System

    PEARL is a high level procedural programming language, which was especially designed for the demanding need to have an expressive and comfortable language for solving multitasking problems when controlling technincal processes. PEARL is an abbreviation for "(P)rocess and (E)xperiment (A)utomation (R)ealtime (L)anguage". It was designed around 1975 at the IRT Institute of the Leibniz University in Hannover with the idea in mind to have an easy to learn programming language for realtime problems. For more, also historical information please visit (http://www.pearl90.de/). In 1998 PEARL-90 was standardized by the Deutsches Institut für Normung e.V. in DIN 66253-2. PEARL provides the standard data types and structures known from other procedural languages like e.g. PASCAL. Additionally PEARL brings special language constructs for managing real-time and multitasking tasks.
