A Design Pattern and Programming Framework for Interactive Metacomputing

Abstract. This paper presents ADIOS, a system for the development of interactively controlled metacomputations. In ADIOS, coarse grain distributed computations, involving several different program components, are structured according to a distributed Model-View-Controller architecture. Design support is offered via interfaces and a base class, through which the fundamental behavior of program components is established within a concrete framework. In addition, appropriate communication mechanisms are provided to back up the data exchange between the various components. Consisting of only few Java classes, ADIOS is lightweight and promotes disciplined prototyping of metacomputations while allowing for the integration of legacy code.
