Developing applications for parallel architectures is a very complicated and arduous task even for expert programmers. There are several issues that must be considered, i.e., the number of CPU’s available, vector processing capabilities, shared memory issues, process communications, and process synchronization, to name a few. Software developers have been trained to view the solution to a selected problem as a sequence of dependent steps or transitions which are applied to some input in an effort to produce the desired results. This approach to problem solving has been enforced by the traditional languages of C, Pascal, and Fortran. In this paper we describe the Interactive Visualization Tool (IVT) developed for the HICOR interactive parallelizing compiler. In particular, the IVT allows users to interactively manipulate a graphical representation of the program to be parallelized. Parameters describing the target architecture may be manipulated interactively to create what-if scenarios for architectural simulation. |
