Solution overview
Introduction
The NVIDIA Triton Inference Server provides a datacenter and cloud inferencing solution optimized for NVIDIA GPUs. The server provides an inference service via an HTTP or gRPC endpoint that allows remote clients to request inferencing for any number of GPU or CPU models being managed by the server.
This README provides step-by-step deployment instructions for models generated during training (as described in the model README). Additionally, this README provides the corresponding deployment scripts that ensure optimal GPU utilization during inferencing on the Triton Inference Server.
Deployment process
The deployment process consists of two steps:
- Conversion. The purpose of conversion is to find the best performing model format supported by the Triton Inference Server. Triton Inference Server uses a number of runtime backends such as TensorRT, LibTorch and ONNX Runtime to support various model types. Refer to Triton documentation for the list of available backends.
- Configuration. Model configuration on the Triton Inference Server, which generates necessary configuration files.
To run benchmarks measuring the model performance in inference, perform the following steps:
-
Start the Triton Inference Server.
The Triton Inference Server container is started in one (possibly remote) container and the ports for gRPC or REST API are exposed.
-
Run accuracy tests.
Produce results that are tested against given accuracy thresholds. Refer to step 8 in the Quick Start Guide.
-
Run performance tests.
Produce latency and throughput results for offline (static batching) and online (dynamic batching) scenarios. Refer to step 10 in the Quick Start Guide.
Setup
Ensure you have the following components:
- NVIDIA Docker
- PyTorch NGC container 21.02
- Triton Inference Server NGC container 21.02
- NVIDIA CUDA repository
- NVIDIA Ampere, Volta or Turing based GPU
Quick Start Guide
To deploy your model on Triton Inference Server perform the following steps using the default parameters of the nnUNet model on the Medical Segmentation Decathlon dataset. For the specifics concerning inference, see the Advanced section.
-
Clone the repository. IMPORTANT: This step is executed on the host computer.
git clone https://github.com/NVIDIA/DeepLearningExamples.git cd DeepLearningExamples/PyTorch/Segmentation/nnUNet
-
Setup the environment on the host computer and start the Triton Inference Server.
source triton/scripts/setup_environment.sh bash triton/scripts/docker/triton_inference_server.sh
-
Build and run a container that extends the NGC PyTorch container with the Triton Inference Server client libraries and dependencies.
bash triton/scripts/docker/build.sh bash triton/scripts/docker/interactive.sh
-
Prepare the deployment configuration and create folders in Docker.
IMPORTANT: These and the following commands must be executed in the PyTorch NGC container.
source triton/scripts/setup_environment.sh
-
Download and pre-process the dataset.
bash triton/scripts/download_data.sh bash triton/scripts/process_dataset.sh
-
Setup parameters for deployment.
source triton/scripts/setup_parameters.sh
-
Convert the model from training to inference format (for example TensorRT).

-
Run the Triton Inference Server performance online tests.
We want to maximize throughput within latency budget constraints.
Dynamic batching is a feature of the Triton Inference Server that allows
inference requests to be combined by the server, so that a batch is
created dynamically, resulting in a reduced average latency.
You can set the Dynamic Batcher parameter max_queue_delay_microseconds
to
indicate the maximum amount of time you are willing to wait and
preferred_batch_size
to indicate your maximum server batch size
in the Triton Inference Server model configuration. The measurements
presented below set the maximum latency to zero to achieve the best latency
possible with good performance.
python triton/run_online_performance_test_on_triton.py \
--server-url ${TRITON_SERVER_URL} \
--model-name ${MODEL_NAME} \
--input-data random \
--batch-sizes ${BATCH_SIZE} \
--triton-instances ${TRITON_INSTANCES} \
--number-of-model-instances ${NUMBER_OF_MODEL_INSTANCES} \
--shared-memory \
--result-path ${SHARED_DIR}/triton_performance_online.csv
- Run the Triton Inference Server performance offline tests.
We want to maximize throughput. It assumes you have your data available for inference or that your data saturate to maximum batch size quickly. Triton Inference Server supports offline scenarios with static batching. Static batching allows inference requests to be served as they are received. The largest improvements to throughput come from increasing the batch size due to efficiency gains in the GPU with larger batches. This example uses shared-memory.
python triton/run_offline_performance_test_on_triton.py \
--server-url ${TRITON_SERVER_URL} \
--model-name ${MODEL_NAME} \
--input-data random \
--batch-sizes ${BATCH_SIZE} \
--triton-instances ${TRITON_INSTANCES} \
--shared-memory \
--result-path ${SHARED_DIR}/triton_performance_offline.csv
Advanced
Triton embedded deployment
Triton embedded deployment means that client and server are running on the same machine (e.g. MRI).
The shared-memory extensions allow a client to communicate input and output tensors by system or CUDA shared memory. Using shared memory instead of sending the tensor data over the GRPC or REST interface can provide significant performance improvement for some use cases. Because both of these extensions are supported, Triton reports "system_shared_memory" and "cuda_shared_memory" in the extensions field of its Server Metadata.
More information about shared memory can be found here Shared memory
Prepare configuration
You can use the environment variables to set the parameters of your inference configuration.
Triton deployment scripts support several inference runtimes listed in the table below:
Inference runtime | Mnemonic used in scripts |
---|---|
TorchScript Tracing | ts-trace |
TorchScript Tracing | ts-script |
ONNX | onnx |
NVIDIA TensorRT | trt |
Example values of some key variables in one configuration:
PRECISION="fp16"
FORMAT="ts-script"
BATCH_SIZE="1, 2, 4"
BACKEND_ACCELERATOR="cuda"
MAX_BATCH_SIZE="4"
NUMBER_OF_MODEL_INSTANCES="1"
TRITON_MAX_QUEUE_DELAY="1"
TRITON_PREFERRED_BATCH_SIZES="2 4"
Latency explanation
A typical Triton Inference Server pipeline can be broken down into the following steps:
- The client serializes the inference request into a message and sends it to the server (Client Send).
- The message travels over the network from the client to the server (Network).
- The message arrives at the server and is deserialized (Server Receive).
- The request is placed on the queue (Server Queue).
- The request is removed from the queue and computed (Server Compute).
- The completed request is serialized in a message and sent back to the client (Server Send).
- The completed message then travels over the network from the server to the client (Network).
- The completed message is deserialized by the client and processed as a completed inference request (Client Receive).
Generally, for local clients, steps 1-4 and 6-8 occupy a small fraction of time, compared to steps 5. As backend deep learning systems like Jasper are rarely exposed directly to end users, but instead only interfacing with local front-end servers, for the sake of Jasper, we can consider that all clients are local.
