<html><HEAD><TITLE> Daisy/DSI Programming System </TITLE></HEAD><H2> Daisy/DSI Programming System </H2><Strong>Description: </Strong> <Blockquote>DSI is an system for <em> symbolic multiprocessing </em>based on the underlying operational model of <em> suspending construction </em>.The fundamental synchronization mechanism in this model is the<em> suspension </em> a transparent object representing a computation.Suspensions evolve into manifest data values, which can be inspected andmanipulated by other computations. Computation is <em> demand oriented, </em>a relaxation of demand-driven computation in which a system with availableprocessing resources can speculatively activate suspensions for boundedexecution. We are interested in this model as a general basis for improvingthe performance of limited-scale multiprocessors.<em> Daisy </em> is a surface language for programming in the DSI system.Daisy is an applicative language (a mutation of Scheme) with provisions forexploiting a suspending list constructor. Among these provisions areconstructs for building networks of streams, including windowing operationsfor stream-based I/O. These facilities make Daisy a good language formodeling networks of self-timed communicating processes. </Blockquote><P><Strong> Associated Faculty: </Strong> <UL><LI> <!WA0><A href="http://www.cs.indiana.edu/people/s/sjohnson.html"> Steven D.
