ScalFMM (Parallel Fast Multipole Library for Large Scale Simulations) offers all the functionalities needed to perform large parallel simulations while enabling an easy customization of the simulation components: kernels, particles and cells. We will present how we use our library on two kinds of application involving boundary integral representations of physical fields. The first one implements isotropic dislocation kernels for Dislocation Dynamics and the second a time dependent kernel for acoustic problems.
