Maybe I'm missing something but should a 13x speedup allow it to run in 1/13th the time? Or maybe the "13x" is only for part of the system and they have a bottleneck somewhere else.

- Igglyboo 12y agoYes but they said 13x speedup not 13x more processors/cores. Probably just a non-technical writeup tbh.
- sp332 12y agoMaybe there's not much point in running it more than once an hour. For example, maybe the forecast is only reported once an hour. Edit: A quote later in the article says "It will allow us to add more precision, more detail, more accuracy". So it's probably increasing the resolution even though the part you quoted sounds like it's not.
