Ettore Di Giacinto f5e9caece1 kernel: reframed Blackwell kernel-gap map (research + profiles)
Key corrections: (1) vLLM 24k is AGGREGATE; single-stream roofline ~3300 t/s
(BF16) / 6600 (FP4). (2) GB10 is 1:1:2 BF16:INT8:FP4 - INT8 == BF16, only FP4 is
2x. (3) Measured: dense int8-MMQ at 21% of ceiling, MoE FP4-MMQ at ~5% - both
EXIST, just untuned for Blackwell. Strategy: to MATCH vLLM, tune MMQ or build a
Marlin-style W4A16 BF16 GEMM (FP4 NOT required); to BEAT, fix the existing FP4
MMA on sm_121 (build/miscompile, not greenfield). Dropped the tcgen05 grouped
GEMM rewrite. Cheap next test: dense MXFP4 quant + existing FP4-MMA.
