Generating the matrices counts towards this time, so you should parallelise the matrix generation. I cannot think of any other time consuming steps. You shouldn't be writing the large matrices to files during your experiments. You are correct, you will need to run `sbatch` for every combination of parameters. The idea is that this should make the sharing of the nodes within the class a bit more democratic -- this way one student cannot use all of our Setonix nodes for several hours, for example. You can still trigger all of your `sbatch` commands from a single script though.
