Shouldn't datacenters attempt to minimize idle time though? A server sitting at idle is a depreciating asset that could likely be put to more productive use if tasks were rescheduled to take advantage of idle time (this would also reduce the total number of servers needed).
- gumby 6y agoThat is definitely the objective but the reality is that load is not* uniform over the day. So you are paying to keep some number of servers hot (I don't know about spinup/spindown practices in modern datacenters). I doubt this applies to HPC (the target market for this part) as they either schedule jobs closely or could, I imagine, shut them down. But I'm not in that space either so this is merely conjecture. * I am sure there are corner cases where the load is uniform, but they are by definition few.
