Examples

graphStatus Mc2GenTaskCallback(const gert::ExeResGenerationContext *context,
    std::vector<std::vector<uint8_t>> &tasks) {
...
  // Set an AI CPU task.
  auto aicpu_task = KernelLaunchInfo::CreateAicpuKfcTask(context,
      "libccl_kernel.so", "RunAicpuKfcSrvLaunch");
  std::vector<ArgDescInfo> aicpu_args_format;
  aicpu_args_format.emplace_back(ArgDescInfo(ArgDescType::kIrOutput, 0));
  //Obtain the IR index in ArgDescInfo of the kIrOutput type. The obtained value is 0.
  auto ir_index = aicpu_args_format.back().GetIrIndex();
...
}
