ParallelCombine

ParallelCombine[f, h[e1, e2, …], comb] evaluates f[h[e1,e2,…]] in parallel by distributing parts of the computation to all parallel kernels and combining the partial results with comb.

ParallelCombine[f, h[e1, e2, …]] is equivalent to ParallelCombine[f,h[e1,e2,…],h] if h has attribute Flat, and ParallelCombine[f,h[e1,e2,…],Join] otherwise.

Examples

ParallelCombine[Total, Range[1000], Plus]
(* 500500 *)

ParallelCombine[Map[f], {a, b, c, d, e}, Join]
(* {f[a], f[b], f[c], f[d], f[e]} *)
