Abstract :
Electromagnetic wave propagation simulations using meshless time-domain method (MTDM) have been accelerated by parallelization techniques on Many Integrated Core (MIC) architecture. Numerical experiments show that, in the symmetric mode with the appropriate number of assigned nodes for each MIC, the simulation is about 9.41 times faster than that of the serial execution on CPU. In addition, in the offload mode with the explicit optimization strategy for MIC, the simulation using MTDM on MIC is about 8.16 times faster than that of the serial execution on CPU.
