I had a great time hosting an “Ask Me Anything” subreddit last Monday. I spent over two hours answering questions posted by Reddit users; mostly about the ALCF, how supercomputing is used in research, and where I think computing is heading. I didn’t know what to expect when I agreed to host this, but it was a lot of fun! Thanks for all the great questions. I’ll try to get to more of them in the next couple of weeks.
