| # Compile Cache — MI300X |
|
|
| Generated: 2026-07-21T05:53:03Z |
|
|
| ## Purpose |
| Records the exact configuration under which the compile cache (inductor + Triton) was built. |
| If unexpected AUTOTUNE blocks appear on a later run, compare the current environment |
| against these values to pinpoint the cache-key mismatch. |
|
|
| ## Hardware |
| - GPU: NVIDIA A100 80GB PCIe |
| - GPU count (world_size): 1 (1) |
| - Architecture: gfx942 (AMD MI300X) |
| |
| ## Software Versions |
| | Package | Version | |
| |---------|---------| |
| | Torch | 2.7.1+cu126 | |
| | HIP / ROCm | N/A | |
| | Triton | 3.3.1 | |
| | ck4inductor | N/A | |
| | Python | 3.11.15 | |
| |
| ## Compile Configuration |
| | Setting | Value | |
| |---------|-------| |
| | Compile backend | inductor | |
| | Compile mode | N/A | |
| | GEMM backends | ATEN | |
| | TORCHINDUCTOR\_CK\_DIR | `N/A` | |
| | TORCHINDUCTOR\_CACHE\_DIR | `/workspace/inductor_cache` | |
| | TRITON\_CACHE\_DIR | `/workspace/triton_cache` | |
| | TRITON\_MAX\_BLOCK\_SIZE | N/A | |
| | TORCHINDUCTOR\_COMPILE\_THREADS | 1 | |
| |
| ## Model |
| - Architecture: EnhancedDSRModel (~1.743B total params) |
| - Trainable params: fp32 (~337M — new alignment modules) |
| - Frozen backbone: bf16 (~1.406B — RWKV-7 1.5B World) |
| - Sequence length: 1024 tokens |
| |
| ## Cache Statistics |
| | Cache | Files | |
| |-------|-------| |
| | inductor\_cache | 615 | |
| | triton\_cache | 6170 | |
| | tar.zst size | 91.6 MB | |
| |
| ## Autotune Cache Key |
| The inductor autotune winner cache key is a **hash of the full candidate set** |
| including which backends are enabled. Adding/removing from |
| `TORCHINDUCTOR_MAX_AUTOTUNE_GEMM_BACKENDS` (currently `ATEN`) will |
| invalidate all cached winners and force a full AUTOTUNE re-run. |
| |
| ## Recompilation Trigger Checklist |
| If AUTOTUNE blocks appear on a pod that should have cache hits, verify: |
| 1. `TORCHINDUCTOR_MAX_AUTOTUNE_GEMM_BACKENDS` == `ATEN` |
| 2. `TORCHINDUCTOR_CK_DIR` points to valid CK root: `N/A` |
| 3. `library/src` symlink inside ck4inductor package exists (needed for gemm_universal kernel enumeration) |
| 4. `TORCHINDUCTOR_CACHE_DIR` == `/workspace/inductor_cache` (with extracted cache files present) |
| 5. `TRITON_CACHE_DIR` == `/workspace/triton_cache` (must NOT be `~/.triton` — that is wiped on restart) |
| 6. Torch version matches: `2.7.1+cu126` — different minor/patch versions can invalidate kernel hashes |
| 7. Triton version matches: `3.3.1` |
