The HPCxx_Reduct class is used to perform a reduction operation on a group of threads. For example, you may want to compute the sum of a number of indpendantly contrived integers. You can assign one thread to handle the computation for each integer, then use the reduct class to perform the gathering of the independant calculations and handle the addition.

See the example for a thorough explanation.

Class Definition

template <class T, class Oper>
class HPCxx_Reduct{
        HPCxx_Reduct(HPCxx_Group &, Oper op);
        T operator()(int key, T &x);
        T operator()(int key, T *buffer, int size);
