You were absolutely right - MoE CPU offloading wasn't working as advertised. 6 | 7 | I've identified and fixed the problem. During testing, some critical code lines got commented out and accidentally stayed that way in the release. The MoE functionality was essentially disabled while still showing the startup messages, which was misleading. 8 | 9 | The fix has been implemented and thoroughly tested with real MoE models. Everything is working correctly now: 10 | 11 | - `--cpu-moe` properly offloads ALL expert tensors to CPU (65-85% VRAM savings) 12 | - `--n-cpu-moe N` offloads first N expert layers as expected 13 | - Memory allocation errors like yours should be resolved 14 | 15 | **Fix commit: `f91e7ca`** 16 | **Documentation: `d97dd24`** 17 | 18 | You can pull the latest version to test it immediately, or wait for the next official release. The MoE CPU offloading is now fully functional and will help with those large model memory issues you were experiencing. 19 | 20 | Thanks for your patience and for helping us catch this. 21 | 22 | -Mic -------------------------------------------------------------------------------- /.mailmap: -------------------------------------------------------------------------------- 1 | # Canonical identity 2 | # "New Name " "Old Name " 3 | # The name-only form maps any commit using that name regardless of email. 4 | 5 | # Canonical author/committer for this repo 6 | Michael Kuykendall Michael A.

This document records the exact loop, the quality gates, and where to find proofs. 4 | 5 | --- 6 | 7 | ## Development Loop 8 | 9 | 1. **Define a contract/spec** 10 | Example: “Implement `/v1/chat/completions` with streaming (Server‑Sent Events) and match the response schema.” 11 | 12 | 2. **Generate a candidate implementation** 13 | AI tools scaffold code; every line is reviewed before commit. Nontrivial changes are tied to a spec (issue or PR description) and include tests. 14 | 15 | 3. **Validate with properties & invariants** 16 | - Property‑based tests: see [`docs/ppt-invariant-testing.md`](./ppt-invariant-testing.md). 17 | - Runtime invariants: assertions on protocol, state, and memory safety expectations. 18 | - Tests live under `/tests` and run in CI on Linux/macOS/Windows. 19 | 20 | 4. **CI Gates** 21 | Every PR runs: 22 | - DCO sign‑off 23 | - Build matrix (Linux/macOS/Windows) 24 | - Unit + property tests 25 | - Static checks / duplicate issue detection 26 | - Release workflow dry‑run (where applicable) 27 | 28 | 5. **Iterate until green** 29 | Code merges only when all gates pass. Releases are signed/tagged and changelogged. 30 | 31 | --- 32 | 33 | ## Quality Practices 34 | 35 | - **Property Testing**: Exercise edge cases beyond example‑based tests. 36 | - **Runtime Invariants**: Fail fast when correctness assumptions are violated. 37 | - **Benchmarks**: Reproducible scripts and environment in [`docs/BENCHMARKS.md`](./BENCHMARKS.md). 38 | - **OpenAI Compat**: Supported endpoints/fields in [`docs/OPENAI_COMPAT.md`](./OPENAI_COMPAT.md). 39 | - **Security Defaults**: 40 | - Binds to `127.0.0.1` by default. 41 | - External model files are **trust‑on‑first‑use**; optional SHA‑256 verification and allow‑list paths are available/planned. 42 | - Prefer running with least privilege; avoid exposing ports publicly without auth. 43 | 44 | --- 45 | 46 | ## Philosophy 47 | 48 | - **Spec first, code second** — logic/contracts drive implementation. 49 | - **Tests > syntax** — correctness is proven with properties/invariants. 50 | - **AI is a tool; process is the product** — the methodology scales teams. 51 | - **Forever‑free core** — MIT license; contributions via Issues/PRs are welcome. 52 | 53 | --- 54 | 55 | ## Quick Links 56 | 57 | - Property/invariant guide: [`docs/ppt-invariant-testing.md`](./ppt-invariant-testing.md) 58 | - Tests: [`/tests`](../tests) 59 | - CI: GitHub Actions → _CI status badge in README_ 60 | - Benchmarks: [`docs/BENCHMARKS.md`](./BENCHMARKS.md) 61 | - OpenAI Compatibility: [`docs/OPENAI_COMPAT.md`](./OPENAI_COMPAT.md) 62 | -------------------------------------------------------------------------------- /libs/headers/ggml-metal.h: -------------------------------------------------------------------------------- 1 | // Note: this description is outdated 2 | // 3 | // An interface allowing to compute ggml_cgraph with Metal 4 | // 5 | // This is a fully functional interface that extends ggml with GPU support for Apple devices. 6 | // A similar interface can be created for other GPU backends (e.g. Vulkan, CUDA, etc.) 7 | // 8 | // How it works? 9 | // 10 | // As long as your program can create and evaluate a ggml_cgraph on the CPU, you can use this 11 | // interface to evaluate the same graph on the GPU.

13 | 14 | 2. **Sept 12, 2025 (commit a752e2e)**: `tests/regression_tests.rs` file created 15 | - Tests were placed inside a module: `mod regression_tests { ... }` 16 | - Test functions existed: `test_model_discovery_functionality`, `test_openai_api_structures_serialization`, etc. 17 | 18 | 3. **Problem**: The bash script and the test file **were created separately** and never properly synchronized 19 | 20 | ### Why Tests Failed: 21 | 22 | The bash script was calling: 23 | ```bash 24 | cargo test test_model_discovery --features huggingface 25 | ``` 26 | 27 | But the actual test is: 28 | - **File**: `tests/regression_tests.rs` 29 | - **Module**: `mod regression_tests { ... }` 30 | - **Function**: `fn test_model_discovery_functionality()` 31 | 32 | Correct call should be: 33 | ```bash 34 | cargo test --test regression_tests test_model_discovery_functionality --features huggingface 35 | ``` 36 | 37 | ## The Fix 38 | 39 | Updated all test calls in `scripts/run-regression-tests.sh`: 40 | 41 | ### Before (WRONG): 42 | ```bash 43 | cargo test test_model_discovery --features huggingface 44 | cargo test test_openai_api --features huggingface 45 | cargo test test_qwen_model_template_detection --features huggingface 46 | cargo test test_custom_model_directory_environment_variables --features huggingface 47 | cargo test test_cli_model_dirs_option_compatibility --features huggingface 48 | cargo test test_error_handling_robustness --features huggingface 49 | ``` 50 | 51 | ### After (CORRECT): 52 | ```bash 53 | cargo test --test regression_tests test_model_discovery_functionality --features huggingface 54 | cargo test --test regression_tests test_openai_api_structures_serialization --features huggingface 55 | cargo test --test regression_tests test_qwen_model_template_detection --features huggingface 56 | cargo test --test regression_tests test_custom_model_directory_environment_variables --features huggingface 57 | cargo test --test regression_tests test_cli_model_dirs_option_compatibility --features huggingface 58 | cargo test --test regression_tests test_error_handling_robustness --features huggingface 59 | ``` 60 | 61 | ## Tests That Were Already Working 62 | 63 | - ✅ Issue #72 (GPU backend): `cargo test --no-default-features --features huggingface,llama-opencl,llama-vulkan gpu_backend` 64 | - This was calling tests in `tests/gpu_backend_tests.rs` correctly 65 | - 9 tests passed including `test_issue_72_gpu_backend_flag_respected` 66 | 67 | - ✅ MLX Support: `tests/mlx_support_regression_test.rs` 68 | - 10 comprehensive MLX tests 69 | - All passing 70 | 71 | - ✅ Release Gates: `tests/release_gate_integration.rs` 72 | - 9 gate validation tests 73 | - Validates CI/CD workflow 74 | 75 | ## Still Missing: MOE Tests 76 | 77 | **Action Required**: Create `tests/moe_cpu_offload_regression_test.rs` with tests for: 78 | - `--cpu-moe` flag functionality 79 | - `--n-cpu-moe N` flag functionality 80 | - MOE feature compilation 81 | - MOE CLI flag parsing 82 | 83 | ## Verification 84 | 85 | Run the fixed script: 86 | ```bash 87 | bash scripts/run-regression-tests.sh 88 | ``` 89 | 90 | All phases should now pass (except MOE tests which don't exist yet). 91 | 92 | ## Lesson Learned 93 | 94 | **Problem**: Test file and test runner script created separately, never synchronized 95 | **Solution**: Either: 96 | 1. Use CI/CD as single source of truth (`.github/workflows/release.yml`) 97 | 2. Migrate to pure Rust tests: `cargo test --workspace` 98 | 3. If using bash scripts, validate test names match actual functions 99 | 100 | **Recommendation**: Deprecate bash script, use GitHub Actions release gates as the authoritative test suite. 101 | --------------------------------------------------------------------------------
