 raitobezarius | sorry | 16:16:54 |
 emily | like what is the Nix-side concurrency | 16:16:56 |
| raitobezarius | per leaf derivation | 16:16:58 |

like what is the Nix-side concurrency you mean in terms of max-jobs? | 16:17:15 |
| emily | and cores yes | 16:17:20 |
| raitobezarius | something like 4C | 16:17:39 |
| raitobezarius | 2-3 max jobs probably | 16:17:44 |
| emily | ok | 16:24:27 |
| emily | do you know the specs of the M2s? | 16:24:30 |
| raitobezarius | the current CI is a M1 | 16:24:45 |
| raitobezarius | the M2 I can give it to you, give me a sec | 16:24:49 |

| emily | 8 GiB :'( | 16:28:20 |
| emily | two VMs probably not viable then | 16:28:48 |
| emily | if you can get Buildkite to only assign slots from the same CL then it seems fine to do 1 | 16:29:24 |
| emily | you need some kind of mutex-y or wrapper thing anyway because you need to make the wipe happen between | 16:29:42 |
| emily | tbh if you have enough Macs then you might be able to skip the VMs and just do MDM wipes between builds and rotate through the machines | 16:30:05 |
| emily | not sure if the total throughput looks better or worse like that | 16:30:10 |
| emily | I do trust MDM wipes on Apple Silicon to be safe from all but the most sophisticated userspace attacks and I don't trust the latter to consider escaping a VM an obstacle | 16:31:13 |
| raitobezarius | https://gerrit.lix.systems/c/lix/+/3765/4?tab=comments redid it | 17:14:05 |

8 GiB :'( if you want to upgrade them for me, you are welcome | 17:14:15 |
| raitobezarius | also why the fuck virtualizing macOS takes more than 500MB ? | 17:14:26 |
| raitobezarius | you can't run macOS headless? | 17:14:32 |
| emily | upgrade… RAM? how could such a thing be accomplished? | 17:14:34 |
| raitobezarius | just desolder and resolder no? | 17:14:40 |
| raitobezarius | don't tell me that the RAM is on the SoC ? | 17:14:45 |
| emily | the very notion is alien | 17:14:45 |
| emily | yes, it's on the SoC | 17:14:49 |
| emily | that's why they have such good memory bandwidth | 17:14:52 |
| raitobezarius | i don't need good memory bandwidth | 17:15:00 |
