> Another example was SPJ's talk about parallel programming in Haskell, where the result was that a 6 core Haskell version was equivalent to a single core C solution. Reminds me of a Rich Hickey talk were he proudly declared that a Clojure solution based on its persistent vector type running on four cores was as fast as the Java/mutable vector solution running on one! The point there was supposed to be that Clojure's inefficiency is more than counterbalanced by the fact that it makes writing parallel code easier. I was not convinced, though. > In the same talk he also boasted that "this is only possible with Haskell", to which an audience member replied that the HPC community had been doing this for well over a decade with FORTRAN. The FP advocates always seem to use examples which show non-interactive processing of "embarrassingly parallel" vector data. And yes, that is trivial in any language. Even in C land all you need to do is to add one keyword / annotation to your for-loop and you are good.
