Data Field Haskell - Dialect with instance of data fields (a generalization of arrays), useful for rapid prototyping of parallel algorithms, and parallel high-level system specification. nhc98 from York - A Haskell 98 compiler. The Glasgow Haskell Compiler (GHC) - An optimizing compiler for Haskell, written in Haskell. Includes extensions for concurrency and heap and time profiling. [Open Source, BSD-like] Hugs - An interpreter for Haskell which runs on almost any platform. Primarily used for teaching. Eden - Parallel functional language to program reactive systems and parallel algorithms using distributed memory. Extends Haskell, but overrules lazy evaluation whenever needed to support parallelism; gives enough control to implement parallel algorithms efficiently, no need for low level details of process management. Kahu Research - Makes Mondrian, light Haskell version to interoperate with other languages in OO environments; runs on .NET (old version for JVM), supports ASP.NET, to embed functional code in webpages with C#. Has version of Glasgow Haskell Compiler using Mondrian for .NET to compile Haskell for .NET. Gofer - Small interpreter for language based on Haskell report 1.2; experimental, more so for type classes. Haskell adopted some ideas of Gofer, but Gofer type class system is more flexible. Runs on DOS, Linux, Macintosh, Unix. Hugs predecessor. Hugs Archive - Many files for Hugs Haskell interpreter: source code, documents. Glasgow Distributed Haskell - GdH combines the multiple processes of Concurrent Haskell with the multiple processing elements of Glasgow Parallel Haskell (GpH). Glasgow Parallel Haskell (GpH) - A Haskell extension for parallel programming built on top of the Glasgow Haskell compiler (GHC). Parallelism is identified using annotations (generally evaluation strategies), that are defined using only two extra primitives: par and seq. pH (MIT parallel Haskell) - A parallel eagerly evaluated variant of Haskell with syntactic provisions for loops, barriers, and I- and M- structure storage. Template Haskell - Haskell 98 extension allowing type-safe compile time metaprogramming, with Haskell, as the manipulating language and the language being manipulated. Haskell++ - Object-oriented Haskell extension, using a preprocessor, supports a form of inheritance via extended class and instance declarations. Descriptions, documents, source download, links. PolyP - Polytypic programming language; source files for compiler written in Haskell that compiles PolyP-code to Haskell; library of polytypic functions written in PolyP, some examples, documents, downloads.
