For semi classical lasing, the FDTD (finite difference timedomain) formulation including nonlinearities is often used.We determine the computational efficiency of such schemesquantitatively and present a hueristic based on space fillingcurves to minimize complexity. The sparse matrix kernel isshown to be optimized by the utilization of Bi-directionalIncremental Compressed Row Storage (BICRS). Extensions to high performance clusters and parallelization are also derived.Presented as a poster at
