From Lucid to TransLucid: Iteration, Dataflow, Intensional and Cartesian Programming

John Plaice, Blanca Mancilla, Gabriel Ditu
2008 Mathematics in Computer Science  
Each successive version of the language has been a generalisation of previous languages, but with a further understanding of the problems at hand.  ...  Indexical Lucid (1987) was introduced for intensional programming, in which the semantics of a variable was understood as a function from a universe of possible worlds to ordinary values.  ...  The current development of a wide variety of manycore and multicore architectures makes the current research in TransLucid of wide relevance.  ...

The GIPSY Architecture [chapter]

Joey Paquet, Peter Kropf
2000 Lecture Notes in Computer Science  
In this paper, we present the design of a General Intensional Programming System (GIPSY). The design and implementation of the GIPSY reflect three main goals: generality, adaptability and efficiency.  ...  The fast growing computer connectivity allows for more and more efficient implementation of distributed applications.  ...  For example, eduction can be a simple one-time process, as in computing in Lucid, or a two-stage show, as in spreadsheet calculations.  ...

First-order functional languages and intensional logic

1997 Journal of functional programming  
From a practical point of view, our investigation provides a formal basis for the tagging mechanism that is used in the implementation of first-order functional languages on dataflow machines.  ...  On the foundational side, the goal of our study is to bring new insights and a better understanding of the nature of functional languages.  ...  The research was supported by the Natural Sciences and Engineering Research Council of Canada and a University of Victoria Graduate Fellowship.  ...

Furthering Baseline Core Lucid Standard Specification in the Context of the History of Lucid, Intensional Programming, and Context-Aware Computing [article]

Joey Paquet, Serguei A. Mokhov
2013 arXiv   pre-print
The resulting Core Lucid language would inherit the properties of generalization attempts of GIPL (1999-2013) and TransLucid (2008-2013) for all future and recent Lucid implementing systems to follow.  ...  We review the historical literature on the Lucid programming language, its dialects, intensional logic, intensional programming, the implementing systems, and context-oriented and context-aware computing  ...  Acknowledgments This research work was funded by the respective grants, faculties and departments of the authors.  ...

Intensional Programming for Agent Communication [chapter]

Vasu S. Alagar, Joey Paquet, Kaiyu Wan
2005 Lecture Notes in Computer Science  
For the language thus extended, a calculus of contexts and a logic of contexts are provided.  ...  This article investigates the intensional programming paradigm for agent communication by introducing context as a first class object in the intensional programming language Lucid.  ...  The implementation technique of evaluation for Lucid programs is an interpreted mode called eduction.  ...
