Compilation Techniques

We propose a novel execution model for the implicitly parallel execution of data parallel programs in the presence of general I/O operations. This model is called hybrid because it combines the advantages of the standard execution models fork/join and SPMD. Based on program analysis the hybrid model adapts itself to one or the other on the granularity of individual instructions. We outline compilation techniques that systematically derive the organization of parallel code from data flow characteristics aiming at the reduction of execution mode switches in general and synchronization/communication requirements in particular. Experiments based on a prototype implementation show the effectiveness of the hybrid execution model for reducing parallel overhead.

Simple Language

It is important for programmers to understand the semantics of a programming language. However, little work has been done about the semantic descriptions of HPF-like data-parallel languages. In this paper, we first define a simple language [Formula: see text], which includes the principal facilities of a data-parallel language such as HPF. Then we present a denotational semantic model of [Formula: see text]. It is useful for understanding the components of an HPF-like language, such as data alignment and distribution directives, forall data-parallel statements.
