ParallelSum
ParallelSum[expr,{i,imax}]
evaluates in parallel the sum 
.
ParallelSum[expr,{i,imin,imax}]
starts with 
.
ParallelSum[expr,{i,imin,imax,di}]
uses steps 
.
ParallelSum[expr,{i,{i1,i2,…}}]
uses successive values 
, 
, …..
ParallelSum[expr,{i,imin,imax},{j,jmin,jmax},…]
evaluates in parallel the multiple sum 
.
Details and Options
- 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,…].
- If an instance of ParallelSum cannot be parallelized it is evaluated using Sum.
- ParallelSum takes the same Method option as Parallelize.
- ParallelSum takes the same DistributedContexts option as ParallelTable.
