On process i, jth value of the <code class="computeroutput">in_values</code> vector is sent to process j and placed in the ith position of the <code class="computeroutput">out_values</code> vector in process <code class="computeroutput">j</code>. The type <code class="computeroutput">T</code> of the values may be any type that is serializable or has an associated MPI data type. If <code class="computeroutput">n</code> is provided, then arrays of <code class="computeroutput">n</code> values will be transferred from one process to another.</p> <p>When the type <code class="computeroutput">T</code> has an associated MPI data type, this routine invokes <code class="computeroutput">MPI_Alltoall</code> to scatter the values.</p> <p> |
