| SomeoneSerge (Ever OOMed by Element) | ShamrockLee (Yueh-Shun Li)jbedo do you know any downsides to this VM-free approach to assembling singularity images? https://github.com/NixOS/nixpkgs/issues/177908#issuecomment-1495625986 | 14:16:57 |
| SomeoneSerge (Ever OOMed by Element) | Finally (lol) got around to trying Nix-built singularity images on the cluster:
❯ nom build .#pkgsCuda.some-pkgs-py.edm.image -L
❯ du -hs $(readlink ./result)
3.4G /nix/store/axhpdc96qgzk720yciwfach93f3xrqby-singularity-image-edm.img
❯ du -hs /scratch/cs/graphics/singularity-images/images/edm.sif # Baseline based off NGC
7.6G /scratch/cs/graphics/singularity-images/images/edm.sif
❯ rsync -LP ./result triton:
❯ ssh triton srun --mem=8G --time=0:05:00 --gres=gpu:a100:1 singularity exec -B /m:/m -B /scratch:/scratch -B /l:/l --nv ./result nixglhost -- python -m edm.example
...
Saving image grid to "imagenet-64x64.png"...
Done

| SomeoneSerge (Ever OOMed by Element) | ShamrockLee (Yueh-Shun Li) btw the squashfs compression is behaving oddly: I went over some threshold maybe and now a 5.7GiB buildEnv maps into an 11GiB sif | 10:10:34 |
| SomeoneSerge (Ever OOMed by Element) | AJAJAJA all you need is ram: I built the same image with memSize = 20 * 1024 instead of 4 * 1024, and now the final result is like 2.8G... | 11:08:56 |

ShamrockLee (Yueh-Shun Li)jbedo do you know any downsides to this VM-free approach to assembling singularity images? https://github.com/NixOS/nixpkgs/issues/177908#issuecomment-1495625986 not aware of any downsides, it's a pretty nice approach | 01:02:55 |

 markuskowa | SomeoneSerge (UTC+2): I'm pretty busy at the moment. I will look at the slurm PR on the weekend. | 08:48:56 |
