ParallelSum

ParallelSum[expr, {i, i_max}]
evaluates in parallel the sum

ParallelSum[expr, {i, i_min, i_max}]
starts with

ParallelSum[expr, {i, i_min, i_max, di}]
uses steps

ParallelSum[expr, {i, {i₁, i₂, ...}}]
uses successive values

ParallelSum[expr, {i, i_min, i_max}, {j, j_min, j_max}, ...]
evaluates in parallel the multiple sum

ParallelSum is a parallel version of Sum, which automatically distributes partial summations among different kernels and processors.

ParallelSum will give the same results as Sum, except for side effects during the computation.

Parallelize[Sum[expr, iter, ...]] is equivalent to ParallelSum[expr, iter, ...].
