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" setting 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. You should make the
number of CPUs and number of GPUs equal for the USER-CUDA package.
