Thanks, Kathryn. My interest is indirect. I don't have an app to use
SCR with, but I am a operating system, storage, and network researcher
that is interested in how file systems can be better designed for
users. I'm glad to hear that SCR will support ordinary files because
it seems like there's a good opportunity for it to take on the use
cases that traditional parallel file systems have difficulty with.

What will the support for ordinary files look like? Will those files
persist on SSD between jobs?

Thanks again,

Andrew
