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

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)

This is not useful on unboxed vectors (will not provide any performance increase)

Re-exported for convenience
