HPS TensorRT Plugin Benchmark for TensorFlow Large Model
Overview
This notebook demonstrates how to benchmark the HPS-integrated TensorRT engine for the TensorFlow large model.
For more details about HPS, please refer to HugeCTR Hierarchical Parameter Server (HPS).
Installation
Use NGC
The HPS TensorRT plugin is preinstalled in the 23.05 and later Merlin TensorFlow Container: nvcr.io/nvidia/merlin/merlin-tensorflow:23.05.
You can check the existence of the required libraries by running the following Python code after launching this container.
import ctypes
plugin_lib_name = "/usr/local/hps_trt/lib/libhps_plugin.so"
plugin_handle = ctypes.CDLL(plugin_lib_name, mode=ctypes.RTLD_GLOBAL)
1. Create the TF model
We define the model graph with native TF layers, i.e., tf.nn.embedding_lookup, tf.keras.layers.Dense and so on. The embedding lookup layer is a placeholder here, which will be replaced by HPS plugin later to support looking up 147GB embedding table efficiently.

2. Build the HPS-integrated TensorRT engine
In order to use HPS in the inference stage, we create JSON configuration file and leverage the 147GB embedding table files in the HPS format.
Then we convert the TF saved model to ONNX, and employ the ONNX GraphSurgoen tool to replace the native TF embedding lookup layer with the placeholder of HPS TensorRT plugin layer.
After that, we can build the TensorRT engine, which is comprised of the HPS TensorRT plugin layer and the dense network.
Step1: Prepare the 147GB embedding table
The current instructions below assume you need to train a 147GB DLRM model from scratch based DeepLearningExamples using the 1TB criteo dataset.
1.1 Train a 147GB model from scratch
Please refer to the Quick Start Guide for DLRM, which contains the following important steps:
Built the training docker container.
Preprocessing the training datasets.
Here you have two options, you can use the 1TB Criteo dataset to train a 147GB model (need to use Spark for data preprocessing), or you can use a synthetic dataset (avoid the preprocessing process) for fast verification.
2.1. Preprocess the Criteo 1TB dataset
A.Please change the frequency limit to2in the step6 .Preprocess the datato generate a training dataset for the 147GB embedding model file.
B. Please ensure that thefinal_output_dirpath is consistent with the input data path in the Part 3 forstep 3 Prepare the benchmark input data.
Note: The frequency limit is used to filter out the categorical values which appear less thanntimes in the whole dataset, and make them be 0. Change this variable to 1 to enable it. The default frequency limit is 15 in the script. You also can change the number as you want by changing the line of OPTS=”–frequency_limit 8”.2.2 Generate synthetic data in the same format as Criteo
Downloading and preprocessing the Criteo 1TB dataset requires a lot of time and disk space. Because of this we provide a synthetic dataset generator that roughly matches Criteo 1TB characteristics. This will enable you to benchmark quickly.Run the training and saved a model checkpoint. If you haven’t completed those steps.
Note:If the model is successfully saved, you will find that each category feature of the Criteo data will export afeauture_*.npyfile, which is the embedding table for each feature, and you will merge these npy files into a complete binary embedding table for HPS in the next step.
1.2 Get the embedding model file in hps format
After completing the model training and getting the 147GB embedding model file, you need to convert the embedding table file to the HPS-format embedding file. In addition: you only need to complete the first three steps in the Quick Start Guide to obtain the HPS-format embedding file.
Build the Merlin HPS docker container.
Run the training docker container built during the training stage.
Convert the model checkpoint into a Triton model repository.
Then you will find a folder named sparse under your deploy_path(The paths provided in steps 2 and 3) for format conversion, from which you can find the two embedding table files(emb_vector and key) in HPS format.
Copy the above two files(
emb_vectorandkey) to the deployment path (model_repo/hps_model/1/dlrm_sparse.model)
!tree -n model_repo/hps_model/1/dlrm_sparse.model
model_repo/hps_model/1/dlrm_sparse.model
├── memb_vector
└── mkey
0 directories, 2 files
Step2: Prepare JSON configuration file for HPS
Please note that the storage format in the dlrm_sparse.model/key file is int64, while the HPS TensorRT plugin currently only support int32 when loading the keys into memory.
Note:In order to facilitate the benchmark test from the minimum batch to the maximum batch, we set the test range to a maximum of 65536. If you want to get better performance, please set each batch independently. For instance, if you set batch=32, it is only used to the case with 32 samples for one batch.

To benchmark with Triton Performance Analyzer, we need to prepare the input data of the required format based on Criteo dataset.
In part 2 section 1.1, we have created the binary dataset in final_output_dir. We provide you with a script to convert this binary data into JSON format that can be fed into the Triton Performance Analyzer. To use the script, you will need the DeepLearningExamples again. Make sure you have add it to your $PYTHONPATH.
If not, please run export PYTHONPATH=/DeepLearningExamples/TensorFlow2/Recommendation/DLRM_and_DCNv2. Remember to replace the path with the correct path in your workspace.
#Create a dir to store the JSON format data
!mkdir -p ./perf_data
Please note that the following script will takes several minutes to finish.
#Run the Python script to convert binary data to JSON format
!python spark2json.py --result-path ./perf_data --dataset_path /path/to/your/binary_split_converted_data --num-benchmark-samples 2000000
Remember to replace the --dataset_path with the correct path in your workspace, and specify the --num-benchmark-samples you want to use.

Step3: Launch the Triton inference server
We can then launch the Triton inference server using the TensorRT backend. Please note that LD_PRELOAD is utilized to load the custom TensorRT plugin (i.e., HPS TensorRT plugin) into Triton.
Note: Since Background processes not supported by Jupyter, please launch the Triton Server according to the following command independently in the background.
LD_PRELOAD=/usr/local/hps_trt/lib/libhps_plugin.so tritonserver –model-repository=/hugectr/hps_trt/notebooks/model_repo/ –load-model=dynamic_3fc_lite_hps_trt –model-control-mode=explicit
If you successfully started tritonserver, you should see a log similar to following:
+--------------------------+---------+--------+
| Model | Version | Status |
+--------------------------+---------+--------+
| dynamic_3fc_lite_hps_trt | 1 | READY |
+--------------------------+---------+--------+
Started GRPCInferenceService at 0.0.0.0:8001
Started HTTPService at 0.0.0.0:8000
Started Metrics Service at 0.0.0.0:8002
We can then benchmark the online inference performance of this HPS-integrated engine with 147GB embedding table.
Step4: Run the benchmark
The reported compute infer number at the server side is the end-to-end inference latency of the engine, which covers HPS embedding lookup and TensorRT forward of dense layers.

4. Benchmark for ARM64 or Grace + Hooper systems
Our prebuilt Grace-optimized ARM64 images are currently undergoing testing, and are therefore not yet available via NGC. This will change soon. If you want to benchmark on ARM and in particular a system equipped with a NVIDIA Grace CPU, you can build a compatible docker image yourself by following these steps.
In some steps we provide 2 mutually exclusive alternatives.
Option A (portable ARM64 HugeCTR): If you follow option A instructions, you will build the standard version of HugeCTR for ARM64 platforms. This approach produces binaries that are more portable, but may not allow you get the most out your Grace+Hopper hardware setup.
Option B (G+H optimized HugeCTR): In contrast, if you follow option B instructions, you will build and run a HugeCTR variant that maximizes DLRM throughput on Grace+Hopper systems. However, please be advised that slight alterations to the system setup are necessary to achieve this. To apply these alterations you must have
rootaccess.es configuration
Step 1: Build the NVIDIA Merlin docker images
Use the following instructions on your ARM system to download and build merlin-base and merlin-tensorflow docker images required for the benchmark.
Option A (portable ARM64 HugeCTR):
git clone https://github.com/NVIDIA-Merlin/Merlin.git cd Merlin/docker docker build -t nvcr.io/nvstaging/merlin/merlin-base:23.09 -f dockerfile.merlin . docker build -t nvcr.io/nvstaging/merlin/merlin-tensorflow:23.09 -f dockerfile.tf . cd ../..
Option B (G+H optimized HugeCTR):
git clone https://github.com/NVIDIA-Merlin/Merlin.git cd Merlin/docker sed -i -e 's/" -DENABLE_INFERENCE=ON/" -DUSE_HUGE_PAGES=ON -DENABLE_INFERENCE=ON/g' dockerfile.merlin docker build -t nvcr.io/nvstaging/merlin/merlin-base:23.09 -f dockerfile.merlin . docker build -t nvcr.io/nvstaging/merlin/merlin-tensorflow:23.09 -f dockerfile.tf . cd ../..
Step 2: Prepare host system for running the docker container
Option A (portable ARM64 HugeCTR): No action required.
Option B (G+H optimized HugeCTR): Adjust your Grace+Hopper system configuration to increase the number of large memory pages for the benchmark.
sudo echo '180000' > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
This make take a while.
In addition, you can reuse the light.json configuration file in Prepare JSON configuration file for HPS.
Step 3: Create the model
Follow to Create TF Create the TF model to create the model. There are many ways to accomplish this. We suggest simply running this Jupyter notebook using the docker image that you just created in your ARM64 / Grace+Hopper node, and forward the web-server port to the host system.
Your filesystem or system environment might impose constraints. The following command just serves as an example. It assumes HugeCTR was downloaded from GitHub into the current working directory (git clone https://github.com/NVIDIA-Merlin/HugeCTR.git). To allow writing files, we first give root user (inside the docker image you are root) to access to the notebook folder (this folder), and then startup a suitable Jupyter server.
export HCTR_SRC="${PWD}/HugeCTR" && chmod -R 777 "${HCTR_SRC}/hps_trt/notebooks" && docker run -it --rm --gpus all --network=host -v ${HCTR_SRC}:/hugectr nvcr.io/nvstaging/merlin/merlin-tensorflow:23.09 jupyter-lab --allow-root --ip 0.0.0.0 --port 8888 --no-browser --notebook-dir=/hugectr/hps_trt/notebooks
Step 4: Prepare data
Next, follow the instructions in Build the HPS-integrated TensorRT engine to create the dataset and the predconditions for benchmarking.
Step 5: Run benchmark
Follow the steps outlined in Benchmark HPS-integrated TensorRT engine on Triton to execute the benchmark itself.
