Mojo struct

KernelGeometry

struct KernelGeometry

Bundles kernel-shape inputs and the derived scheduling counts.

Fields

• ​BM (Int): Block shape M (rows per workgroup tile).
• ​BN (Int): Block shape N (columns per workgroup tile).
• ​BK (Int): Block shape K (reduction dimension per workgroup tile).
• ​MMA_M (Int): MFMA op shape M.
• ​MMA_N (Int): MFMA op shape N.
• ​MMA_K (Int): MFMA op shape K.
• ​elem_bytes (Int): Element size in bytes (1 for FP8, 2 for BF16/FP16, 4 for FP32).
• ​simd_width (Int): SIMD load width in elements (typically simd_width_of[in_type]()).
• ​is_fp8 (Bool): True iff elem_bytes == 1 (FP8 dtypes).
• ​vm_per_load_a (Int): Number of vmcnt entries consumed per channel-A prefetch.
• ​vm_per_load_b (Int): Number of vmcnt entries consumed per channel-B prefetch.
• ​lgkm_per_load_a (Int): Number of lgkmcnt entries consumed per channel-A fragment load.
• ​lgkm_per_load_b (Int): Number of lgkmcnt entries consumed per channel-B fragment load.
