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