Do some interviews with the end users of machines like this. I'm sure that 99% of this site's readership are well familiar with regular server operation, but for many, myself included, supercomputers are well in the land of boffinry.

I'd like to hear from the users to describe the class of problems that require such performance, how they went about it, and what some of the results are.
