MT2203 generators are intended for use in large scale Monte Carlo simulations performed on multi-processor computer systems [Matsumoto2000]_. .. rubric:: Subsequence selection methods support skipAhead (nskip) Not supported leapfrog (threadIdx, nThreads) Not supported Batch Processing **************** Mersenne Twister engine needs the initial condition (``seed``) for state initialization. The seed can be either an integer scalar or a vector of :math:`p` integer elements, the inputs to the respective engine constructors. .. rubric:: Algorithm Parameters MT2203 engine has the following parameters: .. tabularcolumns:: |\Y{0.2}|\Y{0.2}|\Y{0.6}| .. list-table:: Algorithm Parameters for mt2203 engine (Batch Processing) :header-rows: 1 :widths: 10 20 30 :align: left :class: longtable * - Parameter - Default Value - Description * - ``algorithmFPType`` - ``float`` - The floating-point type that the algorithm uses for intermediate computations. Can be ``float`` or ``double``. * - ``method`` - ``defaultDense`` - Performance-oriented computation method; the only method supported by the algorithm. * - ``seed`` - - :math:`777` for a scalar seed - NA for a vector seed - Initial condition for state initialization, scalar or vector: - Scalar, value of ``size_t`` type - Vector, pointer to ``HomogenNumericTable`` of size :math:`1 \times p`
