Okay, my absolute favorite new functionality in the PR I've been working on is being able to do this:
nix build --impure -L .#cudaPackages_11_8.pkgs.xgboost
and build xgboost with cudaPackages_11_8.
This looks nice but also looks like a way to shoot yourself in the foot and/or cause infinite recursion | 21:06:22 |
 connor (he/him) | Has anyone had the opportunity to do anything with Intel Optane's enterprise drives? | 21:08:07 |
| connor (he/him) | Unrelated: has anyone encountered a similar error? Looks like xgboost doesn't build with CUDA 12.4.

Has anyone had the opportunity to do anything with Intel Optane's enterprise drives? I have two of them I bought off ebay that I stuck in my machine. They're fast and high iop, but I haven't felt like they changed the game in any meaningful way. | 21:15:47 |
| connor (he/him) | I've seen a lot of random IO on my builders, so I was thinking about maybe getting one | 21:16:41 |
| Philip Taron (UTC-8) | They go for ~$55-75 USD each on ebay. | 21:20:01 |
| Philip Taron (UTC-8) | Not a lot of downsides if you have the spare M.2 space in your machines. | 21:20:58 |
| SomeoneSerge (matrix works sometimes) | Where do you mount these? | 21:21:50 |
| SomeoneSerge (matrix works sometimes) | As in: how are they more useful than tmpfs? | 21:22:26 |
| Philip Taron (UTC-8) | They're basically not, other than: stable storage and doesn't compete for RAM | 21:23:18 |
| SomeoneSerge (matrix works sometimes) | Ok how do you use them? | 21:23:52 |
| SomeoneSerge (matrix works sometimes) | * Ok how do you use them? | 21:24:06 |
| Philip Taron (UTC-8) | https://wiki.archlinux.org/title/Bcachefs -- yeah, I live on the edge 🙈
They're the "SSD" in front of my actual SSDs | 21:28:12 |
| Philip Taron (UTC-8) | Again, I have done no benchmarking and perceptually, there's no difference. | 21:28:50 |
 aidalgol | SomeoneSerge (UTC+3): Also, what should I do about backporting that PR since the automatic process for doing that failed? | 21:32:42 |
| connor (he/him) | SomeoneSerge (UTC+3): they're basically (slow) non-volatile RAM. Intel initially tried to position it in the datacenter as a tier between fast disks and RAM but it kind of flopped :l
the 4k random read/write is still the best on the market though | 21:33:19 |
| connor (he/him) | Philip Taron (UTC-8): I was looking at the p5800x, which unfortunately doesn't go for that amount :f | 21:35:05 |
| Philip Taron (UTC-8) | Oh yeah, those don't need the crazy software hacks to be made use of like the raw "here's a tiny bit of optane" ones do. | 21:36:21 |

the 4k random read/write is still the best on the market though Yes, conceptually this is clear. Putting this into practice is what sounds non-trivial | 21:41:53 |

Note this should not necessarily be treated as a hard fail, but a reviewer's attention should be drawn to it and github actions have no way of doing that but to raise a 'failure'
🤔 | 08:19:33 |
| SomeoneSerge (matrix works sometimes) | I've never encountered this | 08:19:36 |
| SomeoneSerge (matrix works sometimes) | https://github.com/NixOS/nixpkgs/blob/d091b7f681e8e5c21947e5de45b7f397a57011ae/maintainers/scripts/check-cherry-picks.sh#L52-L59
I still fail to understand what is it exactly that warrants inspection | 08:57:17 |
| SomeoneSerge (matrix works sometimes) | Oh mornings are hard | 08:57:29 |
| aidalgol | A comment for the conditional on line 52 would help a lot. | 09:15:25 |
