The "xyz" settings determine the problem size. The "t" setting
determines the number of timesteps. The "np" setting determines how
many CPUs the problem will be run on, and the "g" settings determines
how many GPUs the problem will run on, i.e. 1 or 2 in this case. You
can use more CPUs than GPUs with the GPU package.
many MPI tasks per compute node the problem will run on, and the "g"
setting determines how many GPUs per compute node the problem will run

than GPUs (both per compute node) with the GPU package.
