<!-- ==================== CLASS DESCRIPTION ==================== -->
<h1 class="epydoc">Class MPIRequest</h1><p class="nomargin-top"></p>
<p>MPI Request</p>
<p>There is no constructor for MPI Request objects. They are returned by
nonblocking send and receives, and are used to query the status of the
message.</p>

<p>Test if communications have completed.</p>
<p>If the operation was a nonblocking send, it returns 0 if the operation
has not completed, and 1 if it has.</p>
<p>If the operation was a nonblocking receive, 0 is returned if the
operation was not completed, and a tuple containing four elements if it
was completed. The four elements are: the array containing the data, the
source process rank (an integer), the message tag (an integer), and the
number of elements that were received (an integer).</p>
<p>Once a test has been successful (i.e. the operation has completed), it
is no longer possible to call wait() or test() on the MPI Request
object.</p>
