GIPSY - General intensional programing system

点击翻译按钮获取中文摘要

The GIPSY project aims at the practical investigation on the intensional programming language paradigm as implemented by the Lucid family of programming languages. Lucid variants range from the famous real-time programming language Lustre, to the C-Lucid hybrid programming system GLU. The Lucid family of programming languages being very eclectic and in constant evolution, the GIPSY project aims at providing a common platform for the compilation, execution and development of Lucid variants. With flexibility and generality in mind, our ongoing research program has allowed us to establish a framework approach to compiler and run-time system construction for the execution of programs written in all variants of Lucid. This approach provides a flexible infrastructure for the semi-automated generation of many components of the GIPSY. Using syntactic and semantic language description and translation rules, components like parsers and semantic analyzers and translators can be automatically generated for all Lucid variants. The compiled programs can be further analyzed to allow optimization of their distributed run-time behavior by implementing various solutions for task scheduling using our semantically sound demand-driven execution model.
