I work with the DOE and was at ORNL before Summit was released (I got to play on Summit-dev). When making these models there is A LOT of exploration happening. There's a whole class of visualization techniques called "in situ" that visualize data as it comes off the press (memory is then dumped because there's neither enough storage space nor can we write to disk fast enough). I'll tell you that there will be a lot of restarting those simulations because the scientists need to explore the data as it is going on. Going in the wrong direction? Made a small mistake that causes cells explode? Realize you're not looking in the right region of interest? You restart the sim (thank god for restart files, right?). Exploration is one of the most important things in research and it is getting more and more difficult. I believe this is what the gp is after. Having these understandings helps you explore the data better. Creating these tools is hard work and takes a lot of collaboration too.
