| # Dockerfile.sd-cli-cu13 — arch-correct multi-arch sd-cli (CUDA 13 toolchain) | |
| # --------------------------------------------------------------------------- | |
| # Companion to Dockerfile.sd-cli-cu12. Same upstream repo + ref + feature flags; | |
| # the ONLY difference between the two images is the CUDA toolkit and therefore | |
| # the architecture list. See Dockerfile.sd-cli-cu12 for the full "why". | |
| # | |
| # WHY A SEPARATE CUDA 13 IMAGE | |
| # setup.py picks the prebuilt by driver: `cu13` when the host CUDA major >= 13, | |
| # else `cu12` (downloads/setup.py fetch_or_build_sdcli). A binary built against | |
| # the CUDA 13 runtime needs the CUDA 13 toolchain. Blackwell boxes on a CUDA 13 | |
| # driver pull THIS one. | |
| # | |
| # CUDA 13 RAISED ITS ARCH FLOOR — the lists differ BY DESIGN. | |
| # CUDA 13 dropped the older virtual/real arches (Maxwell sm_50/52/53, Pascal | |
| # sm_60/61/62, and Volta sm_70). Its supported floor is Turing sm_75. So the | |
| # cu13 list starts at 75-real (NOT 70-real like cu12) and runs up through 120: | |
| # 75-real Turing (RTX 20xx, T4) | |
| # 80-real Ampere (A100) | |
| # 86-real Ampere (RTX 30xx, A10, A40) | |
| # 89-real Ada (RTX 40xx, L4, L40) | |
| # 90-real Hopper (H100, H200) | |
| # 100-real Blackwell DC (B100/B200) | |
| # 120-real Blackwell (RTX 50xx) <-- the whole point | |
| # 120-virtual PTX tail for compute_120 (JIT forward-compat) | |
| # Putting 70-real here would FAIL the build (sm_70 unsupported in CUDA 13) — | |
| # that is the intended divergence, not an omission. Volta/Pascal/Maxwell users | |
| # stay on the cu12 binary, which setup.py already routes them to. | |
| # | |
| # VERIFY: the build prints `nvcc --list-gpu-arch` (CUDA 13) below. If cmake errors | |
| # on an unsupported arch, reconcile CUDA_ARCHS against that printout. | |
| # --------------------------------------------------------------------------- | |
| # CUDA 13 devel. Keep ubuntu22.04 (glibc 2.35) for binary portability, matching | |
| # the cu12 image. VERIFIED 2026-06-11: nvidia/cuda:13.0.1-devel-ubuntu22.04 DOES | |
| # exist on Docker Hub, so cu13 stays on 22.04 / glibc 2.35 — NO elevated glibc | |
| # floor vs cu12. (13.0.1-devel-ubuntu24.04 also exists; only fall back to it if a | |
| # future 13.x drops the 22.04 variant — that would raise the binary's floor to | |
| # glibc 2.39 on provider boxes, so note it on swap if you ever do.) | |
