Methods​

__init__​

def __init__(*, num_q_heads: Int, group: Int, qk_depth: Int, ov_depth: Int, swizzle_mode: TensorMapSwizzle, page_size: Int) -> Self

BM_eff​

def BM_eff(self) -> Int

Number of distinct sequence positions per CTA tile.

When fuse_gqa, each CTA tile covers BM // group seq positions × group heads = BM physical rows.

Returns:

Int

rope_depth​

def rope_depth(self) -> Int

Returns:

Int

num_qo​

def num_qo(self) -> Int

Returns:

Int

correction_smem_elements​

def correction_smem_elements(self) -> Int

Returns:

Int

num_active_warps_per_group​

def num_active_warps_per_group(self) -> Int

Returns:

Int

num_active_threads_per_group​

def num_active_threads_per_group(self) -> Int

Returns:

Int
