    초록 This experiment simulated the fire driven flow of an underground station through parallel processing
    method. Fire analysis program FDS(Fire Dynamics Simulation), using LES(Large Eddy Simulation), has been
    used and a 6-node parallel cluster, each node with 3.0Ghz_2set installed, has been used for parallel
    computation. Simulation model was based on the Kwangju-geumnan subway station. Underground station, and
    the total time for simulation was set at 600s. First, the whole underground passage was divided to 1-Mesh
    and 8-Mesh in order to compare the parallel computation of a single CPU and Multi-CPU. With matrix
    numbers(15×106) more than what a single CPU can handle, fire driven flow from the center of the platform
    and the subway itself was analyzed. As a result, there seemed to be almost no difference between the single
    CPU’s result and the Multi-CPU’s ones. 3×106 grid point one employed to test the computing time with 2CPU
    and 7CPU computation were computable two times and fire times faster than 1CPU respectively. In this study
    it was confirmed that CPU could be overcome by using parallel computation.
