Multiprocessor/multicore computing

Sequential version of QW-Simulator uses only one core during the simulation, and for certain important problems of microwave and millimetre-wave engineering remains beyond reach because of long CPU times required.

QW-MultiSim contains two multithread versions of QW-Simulator:
QW-OMP: this version uses OpenMP programming standard ( to accelerate the FDTD loop, excitation and postprocessings. Because of high parallel efficiency and no changes in the project required in comparison to standard version, the QW-OMP can become the main QW-MultiSim version. QWED recommends using this version as a very convenient, easy and efficient tool for speeding up FDTD calculations.
QW-MTGOMP: combines the advantages of separating the actual FDTD calculations from graphics, Windows event loop, etc. and QW-OMP approach. It is particularly recommended to the users, who need to watch dynamic field distribution, as is typically the case in microwave power applications.
