...Perhaps HPC should be defined problem-down, rather than hardware-up.
Regarding your "Issue #1:"
There are some _nearly_ EP problems that require very minimal, but crucial,
communication (perhaps at long intervals).
As to your "Issue #2:"
"Owned compute" has some advantages over "rented compute." In general, the
control one has over one's owned resources enables applications to run with
greater performance. Some optimizations just demand root access!
