Instead of "Write to disk at most every xx seconds" (sounds like a resource usage limit) maybe "Write intermediate result to disk every xx seconds" would be less ambiguous?
However, there are two checkpointing styles. Einstein apparently can write a checkpoint virtually as often as you allow. Therefore you would sensibly like to limit the checkpoint frequency to "Write at most every xx seconds"; that is, "no more frequently than".
OTH, Rosetta project writes checkpoints only at completion of unit of work which they call a "model". That might be once every 2 hours even though you specified a checkpoint interval of 60 seconds.
Verbiage like you propose "Write intermediate result to disk every xx seconds" would lead one to think that the project will/must checkpoint only at the specified interval, rather than "no more often than". Perhaps a better phrase would be "Write to disk no more often (or frequently) than xx seconds".
