Parallel computer systems for geophysical electromagnetic modeling and inversion problems have been developed rapidly in the past decade addressing the needs of the industrial applications. In this work we present electromagnetics in BSIT, a software framework developed for massively parallel distributed environments. Its flexible structure allows to combine different physical problems with various solution methods and computer architectures. Inversion and forward modeling can be performed on independent grids with a proper interpolation scheme. For the EM modeling, kernels for isotropic and transversely isotropic media have been developed. The simulations show high efficiency and scalability of the code. Joint inversion of EM and other types of geophysical data could be performed in the future.
