Towards Hybrid Intensional Programming with JLucid, Objective Lucid, and General Imperative Compiler Framework in the GIPSY

arXiv:0907.2640

Abstract

Pure Lucid programs are concurrent with very fine granularity. Sequential Threads (STs) are functions introduced to enlarge the grain size; they are passed from server to workers by Communication Procedures (CPs) in the General Intensional Programming System (GIPSY). A JLucid program combines Java code for the STs with Lucid code for parallel control. Thus first, in this thesis, we describe the way in which the new JLucid compiler generates STs and CPs. JLucid also introduces array support. Further exploration goes through the additional transformations that the Lucid family of languages has undergone to enable the use of Java objects and their members, in the Generic Intensional Programming Language (GIPL), and Indexical Lucid: first, in the form of JLucid allowing the use of pseudo-objects, and then through the specifically-designed the Objective Lucid language. The syntax and semantic definitions of Objective Lucid and the meaning of Java objects within an intensional program are provided with discussions and examples. Finally, there are many useful scientific and utility routines written in many imperative programming languages other than Java, for example in C, C++, Fortran, Perl, etc. Therefore, it is wise to provide a framework to facilitate inclusion of these languages into the GIPSY and their use by Lucid programs. A General Imperative Compiler Framework and its concrete implementation is proposed to address this issue.
