Super scale parallel higher-order MOM simulation using 150 thousands CPU cores

The scattering problem of a full scale airplane is solved by Higher-Order MoM using more than 150,000 CPU cores on a supercomputer. The scale of dense complex matrix generated by the scattering problem is more than one million. In order to guarantee the accuracy of MoM, the direct LU solver for the matrix equation is adopted rather than iterative algorithm such as the CG algorithm. The MPI parallel technique is used to construct the code framework. This numerical result make possible that the accurate simulation of electrical large target using MoM.
