A new resonance module, GEMINEWTRN, has been developed in SCALE, it can calculate the continuous-energy neutron flux within the whole two-dimensional geometry, providing us a rigorous solution. However, the new code needs tremendously amount of computation and memory for practical problem. To relieve the computational burden and memory requirement, parallelization has been implemented into GEMINEWTRN, both angular and spatial decomposition have been adopted so that both the computation and the memory requirement on each processor can be saved considerably, and this effort makes the new resonance method much feasible for practical use. Because the two-dimensional geometry capability and SN/ESC solver of GEMINEWTRN come from lattice physics code NEWT, the similar parallel technique has also been implemented into NEWT, which can also save the computation considerably.
