Because the design space is large and complex, we developed a novel computational framework suitable for parallel implementation on compute clusters. Our technique combines advanced global optimization algorithms and finite-element micromagnetic solvers. Targeting data bit densities of $4\\mathrm{Tb}/\\mathrm{in}^2$, we optimize designs for centered, staggered, and shingled BP writing.
