Glasgow Parallel Haskell (GpH) is a simple parallel dialect of the purely functional programming language, Haskell. It uses a semi-explicit model of parallelism, where possible parallel threads are marked by the programmer, and a sophisticated runtime system then decides on the timing of thread creation, allocation to processing elements, migration. There have been several implementations of GpH, covering platforms ranging from single multicore machines through to computational grids or clouds. The best known of these is the GUM implementation that targets both shared-memory and distributed-memory systems using a sophisticated virtual shared-memory abstraction built over a common message-passing layer, but there is a new implementation, GHC-SMP, which directly exploits shared-memory systems, and which targets multicore architectures.
