<details closed><summary>[<b>2025-08-23</b>] (Väinö Hatanpää, on Slack):</summary>

- [Report](https://cels-anl.slack.com/archives/C058HKVJ0QL/p1755957183678639):

> I did some full machine PyTorch benchmarking and there were some
> troublemaker nodes.
> These were >10% slower than others (sample size 1-3, could be randomness,
> but some were reoccurring):
>
> ```bash
> x4514c6s1b0n0 x4208c0s5b0n0 x4311c0s5b0n0 x4102c4s5b0n0 x4314c7s0b0n0 x4608c3s1b0n0 x4711c3s6b0n0
> ```
>
> And these two were hanging with some communication calls, every time I tried:
>
> ```bash
> x4002c2s1b0n0 x4717c7s2b0n0
> ```
