def clusterlaunchcontrol_try_cancel[multicast: Bool = False](result: Pointer[UInt128, address_space=AddressSpace.SHARED], mbar: Pointer[Int64, address_space=AddressSpace.SHARED])

Requests to atomically cancel the cluster launch if it has not started running yet.

Only supported on NVIDIA SM100+ GPUs.

Parameters:

• ​multicast (Bool): Whether to use multicast mode.

Args:

• ​result (Pointer[UInt128, address_space=AddressSpace.SHARED]): A pointer to UInt128 (16B aligned) that will store the result of the cancellation request.
• ​mbar (Pointer[Int64, address_space=AddressSpace.SHARED]): A pointer to an Int64 (8B aligned) memory barrier state.
