Mojo struct
MHATileSummary
struct MHATileSummary[ValidLengthType: OptionalPointer]
Summarizes the dimensions and valid-length metadata of the MHA work grid.
Stores the batch size, maximum number of prompt tiles, optional per-batch
sequence length offsets, and the maximum sequence length, providing the
mapping from linear work-tile indices to (prompt_tile, head, batch)
coordinates.
Parameters
- ValidLengthType (
OptionalPointer): The optional pointer type carrying per-batch sequence length offsets (inferred).
Fields
- batch_size (
UInt32): - max_num_prompt_tiles (
UInt32): - valid_length (
ValidLengthType): - max_seq_len (
UInt32):
