Modular supercomputers contain heterogeneous computing resources on which the user can allocate a hardware mix meeting the demands of the calculation. I discuss motivations for generalizing QCD simulations for use on modular supercomputers, and identify possible models of LQCD simulations suitable for such an environment. I introduce QMOD, a system of libraries in development to enable task-parallelization of existing lattice QCD simulation codes for modular systems. The Jureca cluster at the J\"ulich Supercomputing Centre serves as a test bed for modular supercomputing strategies.
