+Benchmark: SM103 (B300) FP4 Ultra GEMM vs SM100 (B200) NVFP4 GEMM
+===================================================================
+
+This benchmark compares the performance of the SM103-optimized FP4 Ultra
+GEMM kernel against the SM100 NVFP4 GEMM kernel, both running on B300
+hardware.  It also benchmarks the effect of Programmatic Dependent Launch
+(PDL) on the quant->GEMM pipeline, where the GEMM consumer can begin
+before the quant producer finishes.
+
+SM103 kernels use:
+  - K=768 tile (vs K=256 on SM100)
+  - FP4 Ultra MMA (UltraVs16) schedule
+  - NoSmemWarpSpecialized epilogue
+  - Sm103BlockScaledConfig scale factor layout
+
+PDL kernels additionally set:
+  - cudaLaunchAttributeProgrammaticStreamSerialization on quant (producer)
+  - CUTLASS launch_with_pdl=true on GEMM (enables overlap with next kernel)
+
+Usage:
+    python benchmarks/kernels/benchmark_nvfp4_sm103.py [--mode gemm|quant|e2e|pdl|all]
+
+Requirements:
+    - B300 GPU (SM103 / compute capability 10.3)
+    - CUDA >= 12.9
+    - vLLM built with ENABLE_NVFP4_SM100=1 and SM103 support
