|
|
- [x] All unit tests
|
|
- [x] All integration test scripts
|
|
- [x] Test runners
|
|

|
|
|
|
### Pending (Outside Scope)
|
|
- [ ] Full auto-discovery implementation (Task 41)
|
|
- [ ] Integration into training scripts (Task 45)
|
|
- [ ] GPU info detection for cache keys
|
|
- [ ] Real exponential + binary search
|
|
- [ ] Robust OOM detection
|
|
|
|
## Verification Steps
|
|
|
|
### Step 1: Make Scripts Executable
|
|
```bash
|
|
bash tests/make_executable.sh
|
|
```
|
|
**Expected**: All `.sh` files become executable
|
|
|
|
### Step 2: Run Unit Tests
|
|
```bash
|
|
bash tests/run_unit_tests.sh
|
|
```
|
|
**Expected**: Most tests pass (some may have limitations due to stub)
|
|
|
|
### Step 3: Verify File Structure
|
|
```bash
|
|
ls -R tests/
|
|
```
|
|
**Expected**: See all test files and directories
|
|
|
|
### Step 4: Check Documentation
|
|
```bash
|
|
cat tests/README.md
|
|
cat tests/QUICKSTART.md
|
|
```
|
|
**Expected**: Complete documentation exists
|
|
|
|
### Step 5: Try Quick Integration Test (if GPU available)
|
|
```bash
|
|
bash tests/integration/test_single_gpu_discovery.sh
|
|
```
|
|
**Expected**: Runs without errors (may not find optimal batch size with stub)
|
|
|
|

## Next Steps (For Full Implementation)
|
|
|
|
1. **Implement Core Algorithms**

|
|
- [ ] Implement exponential search (1, 2, 4, 8, ...)
|
|
- [ ] Implement binary search refinement
|
|
- [ ] Improve OOM detection in `_test_batch_size()`
|
|
|
|
2. **Integrate with Training Scripts**
|
|
- [ ] Add `--auto_batch_size` flag to base_train.py
|
|
- [ ] Add `--batch_size_margin` flag
|
|
- [ ] Add discovery call before training loop
|
|
- [ ] Add logging messages
|
|
|
|
3. **Test and Validate**
|
|
- [ ] Run unit tests: `bash tests/run_unit_tests.sh`
|
|
- [ ] Run integration tests: `bash tests/run_integration_tests.sh`
|
|
- [ ] Verify all tests pass
|
|
- [ ] Check performance improvements
|
|
|
|
4. **Optimize and Polish**
|
|
- [ ] Tune safety margins
|
|
- [ ] Optimize discovery speed
|
|
- [ ] Add more error handling
|
|
- [ ] Update documentation with results
