Apex on AWS

Introduction

Apex is a technology that enables Mako DOM content, typically loaded from PDF, to be rendered at high speed on a GPU.

This article describes how to run executables on AWS that have been built with the Apex-enabled Mako Core SDK.

Vulkan SDK

Apex uses the Vulkan API layer to queue data and commands to a GPU. Development of Mako projects that make use of the IApexRenderer class will require the Vulkan SDK to be installed. However, the ready built samples such as simpleapexrenderer have Vulkan statically linked, so they can be run on a system with a GPU, providing a suitable driver is installed.

Linux version

Apex is currently only supported on Ubuntu and Alpine.

AWS AMI

The image that’s needed to test Apex is Ubuntu 24.04 with GPU provision:

EC2 instance type: g4dn.xlarge
AMI ID: ami-0df368112825f8d8f (ubuntu/images/hvm-ssd-gp3/ubuntu-noble-24.04-amd64-server-20250305)

Installing the driver

BASH

wget https://uk.download.nvidia.com/tesla/550.90.07/nvidia-driver-local-repo-ubuntu2404-550.90.07_1.0-1_amd64.deb
sudo apt install nvidia-driver-550
?? sudo apt install ./nvidia-driver-local-repo-ubuntu2404-550.90.07_1.0-1_amd64.deb

Unfortunately, a reboot is required for the driver to be fully loaded.

BASH

sudo reboot

Installing Vulkan SDK on Ubuntu

Instructions can be found on the LunarG web site, but in summary, the commands you need are these:

BASH

wget -qO- https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo tee /etc/apt/trusted.gpg.d/lunarg.asc
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-noble.list http://packages.lunarg.com/vulkan/lunarg-vulkan-noble.list
sudo apt update
sudo apt install vulkan-sdk

If you are planning to develop an Apex-enabled Mako application, you will also need some headers and development tools

BASH

sudo apt-get -y install vulkan-headers vulkan-tools glslc libshaderc-dev libvulkan-dev libsm-dev

You may also want Mesa 3D, which is an open-source implementation of the OpenGL, Vulkan, and other graphics APIs. It allows graphics rendering on systems that either don’t have GPU drivers or need software-based rendering. We use it internally for Mako development, as it enables us to unit-test Apex code on VMs that do not have GPU provision.

CODE

sudo apt-get -y install mesa-utils mesa-vulkan-drivers

What happens when the Vulkan libraries are not available?

BASH

./simpleapexrender 01_Cover\ Girl.pdf 01_Cover\ Girl-apex.tif
Exception thrown: [jawsmako/vulkan/vulkanif.cpp:259] Failed to load Vulkan loader library libvulkan.so.1

What happens when the GPU driver is not available?

BASH

 ./simpleapexrender 01_Cover\ Girl.pdf 01_Cover\ Girl-apex.tif
Exception thrown: [jawsmako/vulkan/vulkanif.cpp:699] No suitable Vulkan devices available

Hardware check

Install hwinfo:

BASH

sudo apt install hwinfo

To display GPU information:

BASH

hwinfo --gfxcard
