Description::
The ``rnum2`` keyword directs Dakota to use pseudo-random numbers
generated by the Pecos package.

*Default Behavior*

``rnum2`` is not used by default.  To change this behavior, it must be
specified in conjuction with the ``rng`` keyword.

*Usage Tips*

Use of the Mersenne twister random number generator ( ``mt19937``) is
recommended over ``rnum2``.
