This presumes that everyone is going to be running massive clusters at
huge scale with completely new codes.

That might be true for a few large labs, but I suspect a lot of other
sites are going to be running older, smaller systems with existing codes
that will never get completely rewritten and someone will have to keep
them running.

As I mentioned in another thread the Slurm folks are already working on
that issue through their nonstop plugin which is intended to let jobs
bargain with the scheduler on how to react to failure.

Of course the user codes have to know what to do when something breaks
too (and I don't mean SEGV)...

All the best,
Chris
