We are happy to announce a new release of Eden, a parallel extension of Haskell. The release comprises:
* The GHC-7.4.2-Eden compiler: GHC-7.4.2 extended with the Eden parallel runtime system. * The Eden modules: a library defining the Eden language constructs. * The Eden skeleton library: a comprehensive library with common task and data parallel patterns. * The Eden trace viewer EdenTV: an visualisation and analysis tool for eventlogs of parallel program runs. All resources are available via: http://www.mathematik.uni-marburg.de/~eden Eden extends Haskell with a small set of syntactic constructs for explicit process specification and creation. While providing enough control to implement parallel algorithms efficiently, it frees the programmer from the tedious task of managing low-level details by introducing automatic process handling, synchronisation and communication (via head-strict lazy lists). Eden is tailored for distributed systems but works equally well on multicore architectures. Processes work within disjoint address spaces and do not share any data. This simplifies Eden's implementation as there is no need for global garbage collection. A tutorial is available from http://www.mathematik.uni-marburg.de/~eden/paper/edenCEFP.pdf The compiler release includes binary packages for Linux and Windows, and a source distribution, available from http://www.mathematik.uni-marburg.de/~eden/?content=down_eden_7_4&navi=down Other features: - Extensions for GHC's event logging support. - Built-in serialisation of Haskell data structures (orthogonal to evaluation), see "Orthogonal Serialisation for Haskell", available from http://www.diku.dk/hjemmesider/ansatte/berthold/jbpubl.html - Optimised local communication. - Stand-alone version for multicore, using middleware MPI or PVM for clusters. Eden libraries and tools are available separately from hackage: - Eden modules: http://hackage.haskell.org/package/edenmodules (already included in the Eden compiler) - Eden skeleton library: http://hackage.haskell.org/package/edenskel - EdenTV: http://hackage.haskell.org/package/edentv (uses gtk2hs and glade) When built using a standard GHC, the packages will produce a threaded simulation of Eden. _______________________________________________ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
