PEFPAT - ITDC-164

Keywords: parallel programming environments, parallelisation

Start Date: 1 February 95 / Duration: 30 months

Objectivies and Approach

The general objective of this project is to design an efficient parallel programming environment for assisting the user in writing and evaluating parallel programs, which involves enhancing of the functionality of FPT (Fortran Parallelizing Transformer, a state of art software provided by the University of Ghent) by creating a graphical programming environment, porting the code generation of FPT to the Siemens shared memory multiprocessor platform, using FPT to parallelise real life applications.

The following approaches were used to fulfill these objectives:

Develop a graphical programming environment that can interactively display a procedure call-graph, a data dependence graph, the loop iteration space, a task graph of the source code to expose to user the dependence and partition information of the program.
Instrumenting the program to detect its potential parallelism and to analyse and profile the behaviour and performance of the resulting program.
Port FPT to a shared memory multiprocessor and use benchmark programs to test the practical usefulness of the system.

Progress and Results

Although the Siemens machine had not been received until July 1996, progress was made on the design of programming environment for FPT on SUN workstations. As the standard approaches were used, it is expected that it will not be hard to convey the work to the Siemens machine. The results obtained by the end of June 1996 were as follows:

A graphical user interface of programming environment has been constructed, which includes all necessary menus and commands.
Integration of the code and data structures of FPT to parse the source code and load it into the text window of the system.
Interactively display of a procedure call-graph, a data dependence graph, the loop iteration space, a task graph of the source program in the graphic view window.
Incorporation of program transforming technologies to automatically restructure the program.

Information Dissemination Activities and/or Exploitation

At the last stage of the project, the system developed will be used to exploit the parallelism of benchmark programs, such as SPEC95, to indicate the usefulness of the system by speed up results.
