-Quasiparticle wave functions are distributed uniformly among `np` MPI process. For example if above example is executed on `np=32` then each process is responsible for evolving `nwfip = 46032/32 = 1438.5`. (In practice for this example processes evolve either 1438 or 1439 qpwf). Qpwfs are evolved by GPUs. It requires that for each MPI process a GPU must be assigned. Suppose that the code is executed on `4 nodes`, and each node is equipped with `4 GPUs`. Consider the following execution command:
