## 작업
|
|
|
|
1. `MITC4-ASM-001..003` tests를 먼저 작성한다.
|
|
2. Shell topology를 concrete MITC4 global 24x24 stiffness에 dispatch한다.
|
|
3. Active source-element order로 worker-owned local buffers를 만들고 element당
|
|
576 COO entries에 stable `elementOrder`와 `localOrder`를 부여한다.
|
|
4. Existing `SparseMatrix::fromCoo` canonical reduction과 every diagonal slot을
|
|
보존하며 worker가 global CSR을 직접 수정하지 않게 한다.
|
|
5. Serial/TBB/repeated run CSR bytes/values를 비교하고 identical semantic S4/S4R
|
|
fixtures가 identical K를 만드는지 검증한다.
|
|
|
|
## Acceptance Criteria
|
|
|
|
```powershell
|
|
$requiredBuildPaths=@("C:/git/googletest","C:/Program Files (x86)/Intel/oneAPI/mkl/2026.1/lib/cmake/mkl","C:/Program Files (x86)/Intel/oneAPI/tbb/2023.1/lib/cmake/tbb","C:/Program Files/HDF_Group/HDF5/2.1.1/cmake")
|
|
foreach($p in $requiredBuildPaths){if(-not(Test-Path -LiteralPath $p)){throw "Missing $p"}}
|
|
cmake --fresh -S . -B .harness/build -G "Visual Studio 18 2026" -A x64 `
|
|
"-DFESA_GTEST_SOURCE_DIR=C:/git/googletest" `
|
|
"-DMKL_DIR=C:/Program Files (x86)/Intel/oneAPI/mkl/2026.1/lib/cmake/mkl" `
|
|
"-DTBB_DIR=C:/Program Files (x86)/Intel/oneAPI/tbb/2023.1/lib/cmake/tbb" `
|
|
"-DHDF5_DIR=C:/Program Files/HDF_Group/HDF5/2.1.1/cmake"
|
|
cmake --build .harness/build --config Debug --target fesa_unit_tests
|
|
ctest --test-dir .harness/build -C Debug -R "SparseAssembly" --output-on-failure
|
|
```
|
|
|
|
Four-node/24-DOF RED를 확인하고 minimal GREEN. 이후:
|
|
|
|
```powershell
|
|
cmake --build .harness/build --config Debug --target fesa_unit_tests
|
|
ctest --test-dir .harness/build -C Debug -R "SparseAssembly|DofManager|Mitc4ShellKernel" --output-on-failure
|
|
cmake --build .harness/build --config Debug
|
|
ctest --test-dir .harness/build -C Debug --show-only=json-v1
|
|
ctest --test-dir .harness/build -C Debug --output-on-failure
|
|
```
|
|
|
|
## 검증 및 상태 갱신
|
|
|
|
RED와 deterministic focused/full evidence를 summary에 기록하고 current Step만 갱신한다.
|
|
|
|
## 금지사항
|
|
|
|
- Worker가 global CSR을 직접 갱신하거나 unordered reduction을 사용하지 마라.
|
|
- Source type으로 quadrature/hourglass를 분기하지 마라.
|
|
- Load, solve, recovery를 구현하지 마라.
|
|
- 직접 commit/hook 실행 또는 reference/upstream 변경을 하지 마라.
