A parallelized version of the level-set algorithm based on the MPI technique is presented. TM-polarized plane waves are used to illuminate two-dimensional perfect electric conducting targets. A variety of performance measures such as the efficiency, the load balance, the weak scaling, and the communication/computation times are discussed. For electromagnetic inverse scattering problems, retrieving the target's arbitrary shape and location in real time is considered as a main goal, even as a trade-off with algorithm efficiency. For the three cases considered here, a maximum speedup of 53X-84X is achieved when using 256 processors. However, the overall efficiency of the parallelized level-set algorithm is 21%-33% when using 256 processors and 26%-52% when using 128 processors. The effects of the bottlenecks of the level-set algorithm on the algorithm efficiency are discussed.
