 pie_ | it might not be trivial to build against an old glibc though | 05:50:48 |

 Madoura | So apparently mainline clang can compile and link HIP executables just fine without hipcc.
It still makes sense to follow the official ROCm software stack for nixpkgs, but dang. This would have been a lot easier to just use regular clang. | 15:48:46 |
| pie_ | heh | 15:49:57 |
| pie_ | I still want to work on it but I haven't gotten my little project working yet. Also exams. | 15:50:23 |
| Madoura | Ah I get it.
I've had a lot of free time lately so I've been spending it (without sleeping...) working on porting ROCm to nixpkgs lol.
Theoretically since we have rocmClangStdenv now switching away from hipcc if/when it's needed should be easy for all the ROCm packages. | 15:51:35 |

| SomeoneSerge (back on matrix) | Hi! Just wanted to mention that torchWithRocm is going to require allowUnfree = true when https://github.com/NixOS/nixpkgs/pull/222273 gets merged. I think this needs to be addressed upstream in openai/triton (they unconditionally download and vendor a copy of ptxas from cuda), but I haven't the capacity to handle this now | 19:54:53 |

| Ryan Swart | Kind of a meta question - I am trying to run static nix on an HPC cluster and am running into some roadblocks (with a custom path and disabling the sandbox as much as possible I am still running into permission denied errors - can't chroot or run bubblewrap); given that I have the ability to run arbitrary binaries - is there a way to disable all "special" path modification etc in such a way that common HPC access limitations can allow nix to still build derivations? | 02:28:46 |
| Ryan Swart | I have looked into both static-nix and nix-portable, but neither seem to be a drop-in solution for my case | 02:29:36 |

| John ✒️ | ryantalo: have you tried something like this? https://www.jboy.space/blog/nix-on-hpc.html | 11:56:18 |
| 1 Apr 2023 |
| SomeoneSerge (back on matrix) | Anyone tried running running Nix from Singularity and binding /nix/store? The cluster at my uni won't enable user namespaces, so no unchroot and no bubblewrap for me | 23:44:29 |
| SomeoneSerge (back on matrix) | singularity run --bind /abc:/efg something.sif works, but I want to use singularity-tools.buildImage and that puts e.g. the shell into /nix/store, which then is hidden by the --bind =' | 23:45:35 |
| SomeoneSerge (back on matrix) | And singularity run --overlay is, again, disabled on the cluster xD | 23:45:55 |

disable all "special" path modification etc
Hi, which path modifications are you referring to?

| Ryan Swart | That describes using chroot - which I don't have permissions to do; nix seems to get to a point of reading/writing source files, and takes forever to work through them (like 5 mins+, log example here: https://gist.github.com/ryanswrt/3ebf02bd10e25319f153014698a14c63) and then eventually dies | 13:40:48 |
| 3 Apr 2023 |
| Ryan Swart | It ends up dying with error: setting up a private mount namespace: Operation not permitted | 00:50:04 |
