> Hello all. I'm using the Data.Vector.generate function with a complicated creation function to create a long vector. Is it possible to parallelize the creation of each element?
> Alternatively, if there was something like parMap for vectors, I suppose I could pass id to Data.Vector.generate and use parMap. Does something like this exist?

You may use computeP + fromFunction from Repa. Wrapping of vectors to
Repa arrays (and vice versa) is O(1).
