Examples

graphStatus Mc2GenTaskCallback(const gert::ExeResGenerationContext *context,
    std::vector<std::vector<uint8_t>> &tasks) {
  ...
  // Create an AI CPU task.
  auto aicpu_task = KernelLaunchInfo::CreateAicpuKfcTask(context,
      "libccl_kernel.so", "RunAicpuKfcSrvLaunch");
  // Obtain the attach stream.
  auto stream_infos = context->GetAttachedStreamInfos();
  GE_ASSERT_TRUE(!stream_infos.empty());
  const int64_t attach_stream_id = stream_infos[0].stream_id;
  // Add information to the AI CPU KFC task.
  aicpu_task->SetStreamId(attach_stream_id);
  ...
