Most array languages, including Fortran 90, Matlab, and APL, provide support for referencing arrays by extending the traditional array subscripting construct found in scalar languages. We present an alternative to subseripting that exploits the concept of reg/ons--an index set representation that can be named, manipulated with highlevel operators, and syntnctically separated from array references. This paper develops the concept of region-based programming and describes its benefits in the context of an idealized array language called RL. We show that regions simplify programming, reduce the likelihood of errors, and enable code reuse. Furthermore, we describe how regions accentuate the locality of array expressions and how this locality is important when targeting parallei computers. We also show how the concepts of region-based programming have been used in ZPL, a fully-implemented practical parallel programming language in use by scientists and engineers. In addition, we contrast region-based progrununing with the array reference conslructs of other array languages.

Abstract. An approach towards defining a flexible, commonly programmable, efficient multi-user Virtual Infrastructural Machine (VIM) is proposed. A VIM is a software infrastructure which enables programming a Grid infrastructure scalable at the lowest possible level. This shall be attained by a Virtual Machine with inherent parallel execution, executing compiled and interpreted computer languages on a very complex p-code level. Based on this interactive deformalized (i.e. natural language like) human-Grid interaction languages should be developed, enabling parallel programming to be done by inherently parallel model description of the given problem.
