parVector :: Vector v a => NFData a => Int -> Strategy (v a)

Evaluate the elements of a boxed vector in parallel.

The vector will be divided up into chunks of length less than or equal to the provided chunk size (first argument) and each chunk of elements will be sparked off for evaluation.

Use this along with the parallel package's using function:

    vec `using` (parVector chunkSize)

parVector can not provide any benefits (read: no parallelism) for unboxed vectors!

Re-exported for convenience

NFData a => NFData [a]

(Integral a, NFData a) => NFData (Ratio a)

NFData (Fixed a)

NFData (a -> b)

This instance is for convenience and consistency with seq. This assumes that WHNF is equivalent to NF for functions.

(NFData a, NFData b) => NFData (Either a b)

(NFData a, NFData b) => NFData (a, b)

(Ix a, NFData a, NFData b) => NFData (Array a b)

(NFData a, NFData b, NFData c) => NFData (a, b, c)

(NFData a, NFData b, NFData c, NFData d) => NFData (a, b, c, d)

(NFData a1, NFData a2, NFData a3, NFData a4, NFData a5) => NFData (a1, a2, a3, a4, a5)

(NFData a1, NFData a2, NFData a3, NFData a4, NFData a5, NFData a6) => NFData (a1, a2, a3, a4, a5, a6)

(NFData a1, NFData a2, NFData a3, NFData a4, NFData a5, NFData a6, NFData a7) => NFData (a1, a2, a3, a4, a5, a6, a7)

(NFData a1, NFData a2, NFData a3, NFData a4, NFData a5, NFData a6, NFData a7, NFData a8) => NFData (a1, a2, a3, a4, a5, a6, a7, a8)
