Unity Simulation Pro

Unlock the true power of scalable simulations through a simulation-optimized version of the Unity runtime.

Accelerating cutting-edge simulations

Digital twins. The metaverse. Mimicking the real world entails simulating cutting-edge environments with myriad sensors and multiple avatars and agents.

Unity Simulation Pro – a simulation-optimized runtime build – enables you to run these simulations at scale, on premises or in your private cloud, making it simpler, faster, and more cost-effective to test and train powerful simulations.

How it works

Unity Simulation Pro removes dependencies on systems that do not benefit from simulation, providing an efficient, optimized solution that maximizes your infrastructure investment. It has two key features: headless rendering (running the Unity Player headless) and multi-GPU distributed rendering.

Headless rendering build 

Headless rendering is a simulation-specific version of the Unity Linux runtime optimized for running in a pure headless fashion, without any dependency on the X server and window manager.

This provides simulation-specific performance advantages that can contribute up to 50% in simulation efficiency based on internal benchmarks.

Multi-GPU distributed rendering

Distributed rendering decouples execution of user scripts and CPU tasks from the rendering pipeline, allowing multiple accelerators – and multiple hosts – to share the rendering workload. 

This feature is useful when simulating:

  • Multiple cameras (sensors) 
  • Complex scenes with long render times
  • High-throughput co-simulation that involves hardware-in-the-loop (HIL) or software-in-the-loop (SIL) simulation
Customer story

Training embodied AI agents

The Allen Institute for AI (AI2) used reinforcement learning and Unity Simulation Pro to train a robot to maneuver around a room. Unity Simulation Pro sped up the process from 200 fps using one GPU to over 5,000 fps using 32 GPUs. The time it takes to train their robot was reduced from more than two weeks to less than two hours.

Abhinav Gupta, Associate Professor, Carnegie Mellon University

"AI2-THOR is a pioneering simulation platform with the most diverse repository of indoor scenes, and while it provides highly realistic simulation, this high fidelity is computationally intensive. The headless version of AI2-THOR, which is built on Unity Simulation Pro, enables us to train our models in large clusters. The experiments that used to take weeks to finish, can now finish in just a few days."

Key benefits

Time efficiency

Running simulations in a distributed fashion enables you to iterate and test more. When you tighten the feedback loop, you get results faster and accelerate your time to insights.

Headless rendering

The Linux-based (Vulkan-only) build target with headless rendering support allows you to read data from the framebuffers in the rendering pipeline and write it to disk, thereby removing the overhead of displaying an image to the surface, which is often not required for running simulation workloads.

High simulation throughput

Maintain high throughput in your Unity Simulation project by running multiple camera sensors in your project across multiple accelerators locally or in the cloud. The distributed rendering decouples the execution of the user scripts run on the CPU from the underlying rendering pipeline run on the accelerator.

Runtime player containerization

Removing the dependency on the windowing system allows you to run the executable generated from the build target in a flexible way in various environments. With proper NVIDIA-Docker setup, you can even containerize the application without having to worry about X setup.
