An Implementation of Eden on Top of Concurrent Haskell Silvia Breitinger, Ulrike Klusik, Rita Loogen Philipps-Universität Marburg, Fachbereich Mathematik, Fachgebiet Informatik, Hans Meerwein Straße, Lahnberge, D-35032 Marburg, Germany, {breiting,klusik,loogen}@informatik.uni-marburg.de Abstract. The functional concurrent language Eden is an extension of the lazy functional language Haskell by high level constructs for the explicit specification of dynamically evolving process systems. It employs stream-based implicit communication. In this paper, we describe how Eden can be implemented on top of Con- current Haskell, another concurrent extension of Haskell. This implemen- tation provides valuable insights into the relationship between the two languages. Furthermore, an outlook on the parallel implementation on a distributed memory system is given.
