clusterlaunchcontrol_try_cancel[multicast: Bool = False](result: UnsafePointer[UInt128, address_space=AddressSpace.SHARED], mbar: UnsafePointer[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 (
UnsafePointer[UInt128, address_space=AddressSpace.SHARED]): A pointer toUInt128(16B aligned) that will store the result of the cancellation request. - mbar (
UnsafePointer[Int64, address_space=AddressSpace.SHARED]): A pointer to anInt64(8B aligned) memory barrier state.
