CPDN is quite nice this way, allowing me to minimize work loss when I must restart boinc or the OS. Recent memory issues with ralph have increased my interest in being able to do restarts with minimal loss.

I realize not all applications are predictable in the way CPDN units are, but I'm just wondering, is there any way to tell from Ralph graphics how close the next checkpoint is? E.g. my understanding is that rosetta checkpoints once per model; if that's correct then is there a known # of steps per model?
Or do you just wait for the model # or progress % to change and therefore know after the fact that a checkpoint just occurred?
