vAccel is a hardware acceleration framework, so, in order to use it the system must have a hardware accelerator and its software stack installed in the Host OS. To walk through the requirements for running a vAccel-enabled workload with the jetson-inference plugin, we will use a set of NVIDIA GPUs (GTX 1030, RTX 2060 and a Tesla T4) and a common distribution like Ubuntu.

The Jetson-inference vAccel plugin is based on jetson-inference, a frontend for TensorRT, developed by NVIDIA. This intro section will serve as a guide to install TensorRT, CUDA and jetson inference on a Ubuntu 18.04 system.

Setup NVIDIA custom repos

The first step is to prepare the package system for NVIDIA's custom repos:

# install common utils & get NVIDIA's key
apt-get update && apt-get install -y --no-install-recommends gnupg2 curl ca-certificates wget sudo
curl -fsSL${os}/x86_64/ | apt-key add -

# download repo pkgs and install them
dpkg -i cuda-repo-*.deb
dpkg -i nvidia-machine-learning-repo-*.deb

# update pkg list
apt-get update

Install CUDA and TensorRT

Next, we need to install CUDA and TensorRT:

# install TensorRT
DEBIAN_FRONTEND=noninteractive apt-get install -yy eatmydata && \
    DEBIAN_FRONTEND=noninteractive eatmydata apt-get install -y cuda-11-1 libnvinfer7 libnvonnxparsers7 libnvparsers7 libnvinfer-plugin7

Prepare for building jetson-inference

Following the successful installation of TensorRT, we need to install the requirements for the jetson-inference build system:

apt-get update && apt-get install -y git \
    libnvinfer-dev \
    libnvinfer-plugin-dev \
    libpython3-dev \
    pkg-config \
    python3-libnvinfer-dev \

Finally, we clone jetson-inference:

git clone --recursive
cd jetson-inference

Patch to support GTX 1030 & RTX 2060

To support GTX 1030 and RTX 2060 we need to patch the source tree to add the relevant compute versions (Enable-CM-60-75.patch):

diff --git a/CMakeLists.txt b/CMakeLists.txt
index 46c997dd..d4c3a56c 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt

+               -gencode arch=compute_75,code=sm_75
patch -p1 < Enable-CM-60-75.patch

Then, let's make sure we have a proper compiler & Cmake installed:

ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
apt-get install -y cmake build-essential

Jetson-inference assumes CUDA is installed in /usr/local/cuda. There is a possibility that cuda will be installed in a folder using the version numbering so to make sure the build system can find it we do the following:

ln -sf /usr/local/cuda-11.1 /usr/local/cuda

Building jetson-inference

We create a build dir, enter it prepare the Makefiles:

mkdir build
cd build


Finally, we issue the build command and we install it to our system:

make -j$(nproc)
make install
