/*D:dis_accumulate
NAME:  dis_accumulate - distributed accumulate algorithm (@PACKAGE@-@VERSION@)
DESCRIPTION:       
 STL-like accumulate for distributed containers
 environment.
SYNOPSIS:
  @example
  template<class InputIterator, class Size>
  T dis_accumulate (InputIterator first, Size n);
  @end example
EXAMPLE:
   A sample usage writes:
   @example
     # include "rheolef/array.h"
     # include "rheolef/dis_accumulate.h"
     int main(int argc, char**argv) {
         environment distributed (argc, argv);
         unsigned int n = 100;
         array<double> x(n, 2.0);
         double sum = dis_accumulate(x.begin(),x.size(),x.comm());
         dout << "dot(x,1) = " << sum << endl;
     }
   @end example
