Richard,
No, as a matter of fact it is not. If you can, try applu or apsi -- those
worked for me.
I had two different failure types: benchmarks where I couldn't even get a
valid checkpoint, and benchmarks that failed after restoring the checkpoint
and beginning simulation. Ammp is in the latter category. I'm using
Simpoints' early simulation points to do this, so I'm sometimes
fast-forwarding quite a ways before taking a checkpoint. For the ones that
failed after restoring, I don't think they always failed right away - some
executed for many cycles after restoring before they failed (this was a
while ago, though, so I don't remember for sure). I think they almost all
have the same error message, though -- some sort of page table issue.
If I get some time, I'll try and re-create some of the problems and see if
they still occur, and if I can debug them. It sure would be nice to get
these running.
