Ideally you'd use something modern that invokes your function every hour (cron? :P) so that the rescheduling is detached from the function. I think if generation takes X hours of raw CPU computation where `X >= 1` then as long as you've got C cores and `C > X` you should be OK?

Out of curiosity, why is having the process scheduled tightly with (something akin to) cron ideal to you? atd is, to me, a perfectly reasonable alternative. I guess it depends on the environment a developer finds themselves in when implementing the feature. It might just be easier to setup the next scheduled job than implementing cron-like features in the system that does the executing of scheduled junk.
