Expand description

FP8 E4M3 weight with transposed layout for coalesced prefill GEMM.

B_t: [K, N] — transposed from checkpoint’s B[N, K]. block_scale_t: [K/128, N/128] — transposed from [N/128, K/128]. Enables ~14x faster prefill via w8a16_gemm_t kernel.

Fields§

§weight_t: DevicePtr

[K, N] FP8 E4M3 transposed weight on GPU.

§scale_t: DevicePtr

[K/128, N/128] FP32 transposed block scales on GPU (widened at load).

§n: u32§k: u32
