Hi Norm,
the people behind ParallelArray mostly aren't on es-discuss, so you'll probably have more luck here:

I’ve started to read through the parallel JavaScript proposal and have a novice question
How would you write a dot product
Given:
P1 = parallelArray(1,2,3)
P2 = ParallelArray(4,5,6)
We want to compute
1*4 + 2*5 + 3*6
As far as I can tell, you need a reduce to do the sums, so you first need to construct
P12 = ParallelArray(1*4, 2*5, 3*6)
Is there a way to generate this using map?
