【摘要】The massively parallel Finite‐Difference Time‐Domain(FDTD) computation using 100000 CPU cores is firstly implemented . Test results show that the parallel efficiency can reach up to 65% on 10 240 CPU cores with 128 CPU cores as the benchmark . The research results in this paper indi...
The GPU RAM ofthe compute nodes shadows the head node CPU memory. These systems can be built up to 16compute nodes. Infiniband and Ethernet network protocols provide the fast connection betweenthe different elements. The following sectiondescribes some of the benchmark examplesthat were executed in...

We present an analytical study of the alternating-direction implicit finite-difference time-domain (ADI-FDTD) method for solving time-varying Maxwell's equations and compare its accuracy with that of the Crank-Nicolson (CN) and Yee FDTD schemes. The closed form of the truncation error is obtaine...
Note: as with CPU, the overall memory bandwidth is more important for performance than the number of cores (seeFDTD benchmark on CPU). Simulation Requirements The FDTD GPU solver can only run 3D FDTD simulations. The “express mode” option should be enabled in the FDTD object properties (ad...

The benchmarks of the SSE acceleration on both the multi-CPU workstation and computer cluster have demonstrated the advantages of (vector arithmetic logic unit) VALU acceleration over GPU acceleration. Several engineering applications are employed to demonstrate the performance of parallel FDTD method ...
