Mojo struct
LoadOrderBarrierStorage
struct LoadOrderBarrierStorage
Storage for load order barrier (mainloop → epilogue load coordination).
This single barrier coordinates the mainloop load warp with the epilogue load warp, ensuring the epilogue load doesn't start before the mainloop has issued its prologue TMA operations.
Protocol:
- Mainloop load warp issues prologue loads
- Mainloop load warp calls arrive() on this barrier
- Epilogue load warp waits on this barrier before starting
This prevents TMA resource contention between mainloop and epilogue loads.
Fields
- barrier_storage (
LoadOrderBarrierStorage.BarrierArray.Storage):
