Function wait

Function wait_all

boost::mpi::wait_all — Wait until all non-blocking requests have completed.

Synopsis

// In header: <boost/mpi/nonblocking.hpp>


template<typename ForwardIterator, typename OutputIterator> 
  OutputIterator 
  wait_all(ForwardIterator first, ForwardIterator last, OutputIterator out);
template<typename ForwardIterator> 
  void wait_all(ForwardIterator first, ForwardIterator last);

Description

This routine takes in a set of requests stored in the iterator range [first,last) and waits until all of these requests have been completed. It provides functionality equivalent to MPI_Waitall.

Parameters:

`first`	The iterator that denotes the beginning of the sequence of request objects.
`last`	The iterator that denotes the end of the sequence of request objects.
`out`	If provided, an output iterator through which the status of each request will be emitted. The `status` objects are emitted in the same order as the requests are retrieved from [first,last).

Returns:

If an out parameter was provided, the value out after all of the status objects have been emitted.
