| # Kernel-generation task: Write a fast 8-bit blockwise AdamW kernel (quantised optimiser state) | |
| # | |
| # Adam's two moment buffers are twice the size of the model, which is why 8-bit optimisers exist: each moment is stored as a byte index into a nonlinear 256-entry map plus one fp32 absmax per 2048-element block. Every step has to dequantise both moments through that map, take the AdamW step, and requantise against a NEW block absmax that is not known until the whole block's new moment exists. It is the memory-heaviest kernel in the training loop and it is all bandwidth and lookups. | |

| # SCORING: correctness is a hard gate; the score is achieved GB/s (uncapped leaderboard, 0 if wrong). | |
| # There is no gold solution and no oracle, so nothing has to be vendored or sealed. | |
| # | |
| # TOOLCHAIN POLICY: the agent writes the kernel with Triton (+Gluon), CUDA C++ via nvcc, CUTLASS headers, or | |
| # the CuTe DSL. Enforcement is by ABSENCE, not by scanning: only the permitted toolchain is installed and | |
| # there is no internet, so nothing else can be obtained. | |
