What Is Holoscan?

The Holoscan container is part of NVIDIA Holoscan, the AI sensor processing platform that combines hardware systems for low-latency sensor and network connectivity, optimized libraries for data processing and AI, and core microservices to run streaming, imaging, and other applications, from embedded to edge to cloud. It can be used to build streaming AI pipelines for a variety of domains, including Medical Devices, High Performance Computing at the Edge, Industrial Inspection and more.

In previous releases, the prefix Clara was used to define Holoscan as a platform designed initially for medical devices. As Holoscan has grown, its potential to serve other areas has become apparent. With version 0.4.0, we're proud to announce that the Holoscan SDK is now officially built to be domain-agnostic and can be used to build sensor AI applications in multiple domains. Note that some of the content of the SDK (sample applications) or the documentation might still appear to be healthcare-specific pending additional updates. Going forward, domain specific content will be hosted on the HoloHub repository.

The Holoscan container includes the Holoscan libraries, GXF extensions, headers, example source code, and sample datasets, as well as all the dependencies that were tested with Holoscan. It is the recommended way to run the Holoscan examples, while still allowing you to create your own C++ and Python Holoscan application.

What Is IGX Holoscan Production Branch October 2023?

The IGX Holoscan Production Branch, part of NVIDIA AI Enterprise -IGX and purpose-built for NVIDIA IGX Orin platforms, provides an API-stable branch that includes monthly fixes for high and critical software vulnerabilities. This branch provides a stable and secure environment for building your mission-critical AI applications running at the edge. The Holoscan production branch releases every six months with a three-month overlap between two releases.

Getting started with IGX Holoscan Production Branch

Before you start, ensure that your environment is set up by following one of the deployment guides available in the NVIDIA IGX Orin Documentation

Visit the Holoscan User Guide to get started with the Holoscan SDK

Holoscan Prerequisites

Prerequisites for each supported platform are documented in the user guide.

On x86_64, you'll need the NVIDIA Container Toolkit version 1.14.1 and Docker. These should already be installed as part of IGX SW 1.0+.

Running the container

  1. Log in to the NGC docker registry

    docker login nvcr.io
    
  2. Press the Get Container button at the top of this webpage and choose the version you want to use. You can set it as NGC_CONTAINER_IMAGE_PATH in your terminal for the next steps to use:

    # For example
    export NGC_CONTAINER_IMAGE_PATH="nvcr.io/nvaie/holoscan-pb23h2:23.10.05-igpu"
    
  3. If using a display, ensure that X11 is configured to allow commands from docker:

    xhost +local:docker
    
  4. Start the container

    docker run -it --rm --net host \
      --runtime=nvidia \
      -e NVIDIA_DRIVER_CAPABILITIES=all \
      -v /tmp/.X11-unix:/tmp/.X11-unix \
      -e DISPLAY=$DISPLAY \
      --ipc=host \
      --cap-add=CAP_SYS_PTRACE \
      --ulimit memlock=-1 \
      --ulimit stack=67108864 \
      ${NGC_CONTAINER_IMAGE_PATH}
    
    • --runtime=nvidia and -e NVIDIA_DRIVER_CAPABILITIES are properties of the nvidia container toolkit to leverage the NVIDIA GPUs and their capabilities. Read more here.
    • -v /tmp/.X11-unix and -e DISPLAY are needed to enable X11 display forwarding.
    • --ipc=host, --cap-add=CAP_SYS_PTRACE, --ulimit memlock=-1 and --ulimit stack=67108864 are required to run distributed applications with UCX. Read more here.

    To expose additional hardware devices from your host to the container, add the --privileged flag to docker run (not secure), or mount their explicit device nodes by adding the flags below:

    • AJA capture card: add --device /dev/ajantv20 (and/or ajantv2<n>).
    • V4L2 video devices (HDMI IN, USB): add --device /dev/video0 (and/or video<n>)
      • If configuring a non-root user in the container, add --group-add video or ensure the user has appropriate permissions to the video device nodes (/dev/video*).
      • If using HDMI IN from a developer kit, also add --device /dev/capture-vi-channel0 to access the Tegra Video Input channels. You might need to add more nodes (with the last digit increasing) depending on the number of channels needed.
    • ConnectX RDMA: add --device /dev/infiniband/rdma_cm and --device /dev/infiniband/uverbs0 (and/or uverbs<n>).
      • This requires the MOFED drivers installed on the host.
      • Needed for RDMA (RoCE or Infiniband). Not required for simple TCP Ethernet communication through a ConnectX SmartNIC.

    If configuring a non-root user in the container, ensure the user has appropriate permissions to the dri device nodes (/dev/dri/*). This can be done by adding --group-add $(cat /etc/group | grep "video" | cut -d: -f3) and --group-add $(cat /etc/group | grep "render" | cut -d: -f3) (Note: simply passing --group-add render might not work if the group id differs between your host and container, even if mounting /etc/group)

Using the installed libraries and headers

The Holoscan SDK is installed under /opt/nvidia/holoscan. It includes a CMake configuration file inside lib/cmake/holoscan, allowing you to import holoscan in your CMake project (link libraries + include headers):

find_package(holoscan REQUIRED CONFIG PATHS "/opt/nvidia/holoscan")
target_link_libraries(yourTarget PUBLIC holoscan::core)

Alternatives to hardcoding PATHS inside find_package in CMake are listed under the Config Mode Search Procedure documentation.

Examples

Python, C++, and GXF examples are installed in /opt/nvidia/holoscan/examples alongside their source code, and run instructions (also available on the GitHub repository).

Running the examples

Example to run the Hello World example:

# Python
python3 /opt/nvidia/holoscan/examples/hello_world/python/hello_world.py


# C++
cd /opt/nvidia/holoscan/examples
./hello_world/cpp/hello_world

Make sure to edit any relative path in the yaml config if you want to run from a different working directory.

Building the examples

You can rebuild the C++ and GXF examples as-is or copy them anywhere on your system to experiment with.

Example to build all the C++ and GXF examples:


export src_dir="/opt/nvidia/holoscan/examples/" # Add "<example_of_your_choice>/cpp" to build a specific example
export build_dir="</path/of/your/choice/>"

cmake -S $src_dir -B $build_dir -G Ninja \
  -D Holoscan_ROOT="/opt/nvidia/holoscan"
cmake --build $build_dir -j

Also see the HoloHub repository for a collection of Holoscan operators and applications which you can use in your pipeline or for reference.
