Mojo struct
QueuedTileScheduler
struct QueuedTileScheduler[tile_shape: UInt32, num_heads: UInt32, /, decoding: Bool, num_ctas: UInt32 = SIMD(GPUInfo.from_family(AcceleratorArchitectureFamily(Int(32), Int(2048), Int(233472), Int(65536), Int(1024)), StringSlice("H100"), Vendor(Int8(2)), StringSlice("cuda"), StringSlice("hopper"), SIMD(9), StringSlice("sm_90a"), Int(132)).sm_count), schedule: MHASchedule = MHASchedule.DEFAULT]
If decoding == False, then num_heads is q_num_heads. If decoding == True, then num_heads is kv_num_heads.

Methods
__init__
def __init__(gidx_ptr: UnsafePointer[UInt32, MutAnyOrigin]) -> Self
get_current_work_info
def get_current_work_info[ValidLengthType: OptionalPointer, //](self, ts: MHATileSummary[ValidLengthType], state: MHATileState) -> WorkInfo
Returns:
advance
def advance[ValidLengthType: OptionalPointer, //, producer: Bool, sync: MHASchedulerSynchronization = MHASchedulerSynchronization.DEFAULT](self, ts: MHATileSummary[ValidLengthType], mut state: MHATileState, pipeline_idx: UInt32) -> OptionalReg[SeqInfo]
The parameter func must return a Bool indicating whether the WorkInfo arg is valid. This function returns whether the current idx corresponds to a valid WorkInfo. Note that if MHASchedulerSynchronization is NONE, then we assume it is only called by thread_idx.x==0.
Returns:
grid_dim
static def grid_dim(batch_size: UInt32, max_num_prompt_tiles: UInt32) -> Tuple[Int, Int, Int]
Returns:
initial_state
def initial_state[ValidLengthType: OptionalPointer, //](self, ptr: UnsafePointer[UInt32, MutAnyOrigin, address_space=AddressSpace.SHARED], tile_summary: MHATileSummary[ValidLengthType]) -> MHATileState
Returns:
unsafe_seq_info
def unsafe_seq_info[ValidLengthType: OptionalPointer, //](self, ts: MHATileSummary[ValidLengthType], state: MHATileState) -> SeqInfo
Returns:
get_type_name
static def get_type_name() -> String
Gets the name of the host type (the one implementing this trait).
Returns:
String: The host type's name.
