[Haskell-cafe] parallelism and purity

Hi cafe, I received questions about parallelism in Haskell. I'm familiar with concurrency but not with parallelism. So, let me ask: Q1) Are there any *applications* using Haskell parallelism? Q2) What kind of parallelism is used in the application? - Task parallel - Data parallel - Data-flow paralle? - etc Q3) Does Haskell purity contribute for the application in the parallelism point of view? I'm one of the translators of "Parallel and Concurrent Programming in Haskell" into Japanese. So, please don't say read the book. :-) --Kazu
