# 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`
