Would that still solve the problem if there are overlapping indexes in
gi ? (i.e. if the same index appeared more than one time and was
utilized from more than one thread at a time)

The examples in the RcppParallel documentation assume that access to
vectors and matrixes are *aligned* (i.e. fall into neat buckets
whereby reading and writing doesn't overlap between worker instances).
Your example appears to access arbitrary elements of sg (depending on
what's passed in gi) whic
Yes it is the same question on SO and I did consider RHertel's comments.
But this problem (sums by group id) is not parallelFor it is parallelReduce:
I split vector, calculate sums and then aggregate those sums.
Please correct me if I am wrong.
