Hopper doesn't have scratch1.
I never was convinced that I needed so many accumulated multiplications, and on hopper the tradeoff is stronger.  (Ideally we run more processes per node because the memory access times are less uniform, and memory is more constrained on hopper.)  So, to make jobs less likely to die (and easier for non-experts to run), reduce the number of accumulated multiplications.
Give jobs two hours, by default, to run.  This should mean they succeed in most cases, and although the wait-times may be a little bit longer, for inexperienced users this is probably the better trade-off.
