> Developing models and running simulations is a core activity of our research department. Faster languages (Julia) and better algorithms result typically not in less computation, but in more ambitious targets. During a discussion about how we can minimize our environmental footprint, we realized that we do not have an idea how much energy our simulations require. I was therefore wondering if there is a easy way to measure the energy consumption of long running computations? It doesn’t need to v…
