If so, <code class="computeroutput">is_mpi_op<Op,T></code> will derive from <code class="computeroutput">mpl::false_</code> and will contain a static member function <code class="computeroutput">op</code> that takes no arguments but returns the associated <code class="computeroutput">MPI_Op</code> value. For instance, <code class="computeroutput"><a class="link" href="is_mpi_op.html" title="Struct template is_mpi_op">is_mpi_op</a><std::plus<int></code>,int>::op() returns <code class="computeroutput">MPI_SUM</code>.</p> <p>Users may specialize <code class="computeroutput"><a class="link" href="is_mpi_op.html" title="Struct template is_mpi_op">is_mpi_op</a></code> for any other class templates that map onto operations that have <code class="computeroutput">MPI_Op</code> equivalences, such as bitwise OR, logical and, or maximum. However, users are encouraged to use the standard function objects in the <code class="computeroutput">functional</code> and <code class="computeroutput">boost/mpi/operations.hpp</code> headers whenever possible. For function objects that are class templates with a single template parameter, it may be easier to specialize <code class="computeroutput">is_builtin_mpi_op</code>. </p> </div> |
