HPS TensorRT Plugin Demo for HugeCTR Trained Model
Overview
This notebook demonstrates how to build and deploy the HPS-integrated TensorRT engine for the model trained with HugeCTR.
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 HugeCTR Container: nvcr.io/nvidia/merlin/merlin-hugectr: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)
Data Generation
HugeCTR provides a tool to generate synthetic datasets. The Data Generator is capable of generating datasets of different file formats and different distributions. We will generate one-hot Parquet datasets with power-law distribution for this notebook:

Train with HugeCTR
We can train a DLRM model with HugeCTR Python APIs. The trained sparse and dense model files will be saved separately. The model graph will be dumped into a JSON file.

Build the HPS-integrated TensorRT engine
The sparse saved model dlrm_hugectr0_sparse_1000.model is already in the format that HPS requires. In order to use HPS in the inference stage, we need to create JSON configuration file for HPS.
Then we convert the dense saved model dlrm_hugectr_dense_1000.model to ONNX using hugectr2onnx, and employ the ONNX GraphSurgoen tool to replace the input embedding vectors with 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 JSON configuration file for HPS
Please note that the storage format in the dlrm_hugectr0_sparse_1000.model/key file is int64, while the HPS TensorRT plugin only supports int32 when loading the keys into memory. There is no overflow since the key value range is 0~260000.

Succesfully build the TensorRT engine
Deploy HPS-integrated TensorRT engine on Triton
In order to deploy the TensorRT engine with the Triton TensorRT backend, we need to create the model repository and define the config.pbtxt first.
!mkdir -p model_repo/dlrm_hugectr_with_hps/1
!mv dlrm_hugectr_with_hps.trt model_repo/dlrm_hugectr_with_hps/1
%%writefile model_repo/dlrm_hugectr_with_hps/config.pbtxt
platform: "tensorrt_plan"
default_model_filename: "dlrm_hugectr_with_hps.trt"
backend: "tensorrt"
max_batch_size: 0
input [
{
name: "categorical_features"
data_type: TYPE_INT32
dims: [-1,26]
},
{
name: "numerical_features"
data_type: TYPE_FP32
dims: [-1,13]
}
]
output [
{
name: "label"
data_type: TYPE_FP32
dims: [-1,1]
}
]

]
Writing model_repo/dlrm_hugectr_with_hps/config.pbtxt
!tree model_repo/dlrm_hugectr_with_hps
model_repo/dlrm_hugectr_with_hps
├── 1
│ └── dlrm_hugectr_with_hps.trt
└── config.pbtxt
1 directory, 2 files
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=dlrm_hugectr_with_hps –model-control-mode=explicit
If you successfully started tritonserver, you should see a log similar to following:
+----------+--------------------------------+--------------------------------+
| Backend | Path | Config |
+----------+--------------------------------+--------------------------------+
| tensorrt | /opt/tritonserver/backends/ten | {"cmdline":{"auto-complete-con |

We can then send the requests to the Triton inference server using the HTTP client.
