JEDI

Jetson-aware Embedded Deep learning Inference acceleration framework with TensorRT

JEDI is a simple framework to apply various parallelization techniques on tkDNN-based deep learning applications running on NVIDIA Jetson boards such as NVIDIA Jetson AGX Xavier and NVIDIA Jetson Xavier NX.

The main goal of this tool is applying various parallelization techniques to maximize the throughput of deep learning applications.

Applied Deep Learning Acceleration Techniques

• Preprocessing parallelization
• Postprocessing parallelization
• Intra-network pipelining with GPU and DLA
• Stream assignment per each pipelining stage

Supported Platforms

• NVIDIA Jetson boards are supported. (Tested on NVIDIA Jetson AGX Xavier and NVIDIA Jetson Xavier NX)

Prerequisite

• Forked tkDNN
• All dependencies required by tkDNN
• Jetpack 4.3 or higher
• libconfig++
• OpenMP

How to Compile JEDI

After installing the forked version of tkDNN, compile the JEDI with the following commands.

git clone https://github.com/urmydata/tkDNN.git
mkdir build && cd build
cmake ..
make

How to Run JEDI

• To run JEDI, the following parameters are needed.

./build/bin/proc -c <JEDI configuration file> -r <JSON result file> -p <tegrastats log> -t <inference time output file>

where

• -c <JEDI configration file>: JEDI configuration file (explanation of JEDI configuration file is shown in here)

• -r <JSON result file> (optional): Output file of detection results in COCO JSON format.

• -p <tegrastats log output file> (optional): Tegrastats log output file during inference which is used for computing the utilization and power.

• -t <inference time output file> (optional): The output file which contains the total inference time

• Example commands of running JEDI

./build/bin/proc -h                                              # print help message
./build/bin/proc -c sample.cfg -r result.json -p power.log       # an example of running

JEDI Configuration Parameters

• JEDI configuration file is based on libconfg format.
• sample.cfg is a sample configuration file with detailed explanation of each configuration parameters

How to Add a New Application in JEDI

• JEDI provides an inteface to add a new tkDNN-based deep learning application.
• Currently, YoloApplication and CenternetApplication are implemented.

1. Write your own deep learning application with the inference application implementation interface

• readCustomOptions: Add a custom option which is used for this application.
• createNetwork: Create a tkDNN-based network
• referNetworkRTInfo: Refer NetworkRT class if any information in this class is needed
• initializePreprocessing: Initialize preprocessing and input dataset
• initializePostprocessing: Initialize postprocessing
• preprocessing: Execute preprocessing
• postprocessing: Execute postprocessing (batched execution must be performed inside this method)
• Call order: readCustomOptions => createNetwork => referNetworkRTInfo => initializePreprocessing => initializePostprocessing => preprocessing/postprocessing
• You can also implement your own dataset with dataset implementation interface

2. Register your application with the following code in your source code.

REGISTER_JEDI_APPLICATION([Your application class name]);

3. Add your source code to CMakeLists.txt
4. Insert app_type = "[Your application class name]" in the JEDI configuration file.
