An environment for programming networks of sequential and parallel computers. ConCoord offers two contributions to ref="module.php?name=Lexikon&file=search&eid=1&query=concurrent">concurrent programming. First, it supports explicit exploitation of a variety of grains of concurrency. Second, it separates the treatment of sequential and of concurrent aspects of programming into computation and "coordination" respectively. Sequential ref="module.php?name=Lexikon&file=search&eid=1&query=algorithm">algorithms can be reused within computation and concurrent ones within coordination. (1995-05-01)
