Thanks Richard. This is exactly what I needed!

With contributions from CMU and a few of our smaller collaborators, we might get to 50M this year. So that would be my range for the coming year, 35M - 50M. Beyond that, we need to start planning now on how we are going to grow. But it will be a challenge to ramp up from ~1Mhr over the past year to 40Mhr. We will need to demonstrate our ability to effectively consume this much simulation before looking for more resources.
