An extended interval temporal logic and a framing technique for temporal logic programming

PhD ThesisTemporal logic programming is a paradigm for specification and verification of concurrent programs in which a program can be written, and the properties of the program can be described and verified in a same notation. However, there are many aspects of programming in temporal logics that are not well-understood. One such an aspect is concurrent programming, another is framing and the third is synchronous communication for parallel processes. This thesis extends the original Interval Temporal Logic (ITL) to include infinite models, past operators, and a new projection operator for dealing with concurrent computation, synchronous communication, and framing in the context of temporal logic programming. The thesis generalizes the original ITL to include past operators such as previous and past chop, and extends the model to include infinite intervals. A considerable collection of logic laws regarding both propositional and first order logics is formalized and proved within model theory. After that, a subset of the extended ITL is formalized as a programming language, called extended Tempura. These extensions, as in their logic basis, include infinite models, the previous operator, projection and framing constructs. A normal form for programs within the extended Tempura is demonstrated. Next, a new projection operator is introduced. In the new construct, the sub-processes are autonomous; each process has the right to specify its own interval over which it is executed. The thesis presents a framing technique for temporal logic programming, which includes the definitions of new assignments, the assignment flag and the framing operator, the formalization of algebraic properties of the framing operator, the minimal model semantics of framed programs, as well as an executable framed interpreter. The synchronous communication operator await is based directly on the proposed framing technique. It enables us to deal with concurrent computation. Based on EITL and await operator, a framed concurrent temporal logic programming language, FTLL, is formally defined within EITL. Finally, the thesis describes a framed interpreter for the extended Tempura which has been developed in SICSTUS prolog. In the new interpreter, the implementation of new assignments, the frame operator, the await operator, and the new projection operator are all included

Compilation and Automatic Parallelisation of Functional Code for Data-Parallel Architectures

Over recent years, there has been a stagnation of the increase in CPU clock speed, and consequently, it has become increasingly popular to offload general-purpose computing problems to graphics processors to try to exploit the massively data-parallel processing capabilities of these devices.This project presents the design of a functional programming language and the implementation of a prototype compiler which aims to produce code that exploits the powerful processing capabilities of data-parallel hardware components, such as CUDA enabled graphics processors. One of the long-term goals is to provide programmers with a tool that simplifies the development of algorithms for parallel architectures.Previous work in the area of automatic parallellisation of code is predominantly concerned with the exploitation of task parallelism in functional languages, such as Lisp and Haskell, and data parallelism in imperative languages, such as Fortran. In the cases where data-parallelism has been exploited in functional languages, e.g., in Data Parallel Haskell, this has mostly been done by introducing library support for CUDA, OpenCL and other data-parallel frameworks.The main focus in the course of this project has been directed towards the optimisation techniques that can be applied to seemingly sequential, functional-style code to prepare it for automatic parallelisation. The pre-eminent transformation in this context is the conversion of augmenting recursion and tail recursion into iteration which, consequently,can enable the translation of iterative constructs into parallel loops, given that there are no loop-carried dependences.Thee compiler strives to identify natural mapping and reduction constructs in sequential code. Furthermore, a dynamic performance model is employed to ensure that only beneficial sections of the code are parallelised. It is concluded from the initial results, that tenfold to hundredfold speed-ups can be achieved from the parallelisation of sequential representations of naturally data-parallel constructs, depending on the pointof comparison
