How difficult would it be in the practical sense to keep all of the cores on something like this "fed" with enough information to get benefits from its concurrency?
I mean to "feed" all 64 cores enough data/code so they can all "do something" concurrently is one hell of a job all on its own!
Depends a lot on the type of problem, and I think that's going to be what makes or breaks them. They have some good examples, but you're right, it's a hard problem and one of the reasons it's so important for them to get these dev boards out.
