Start up a CentOS 7.5 server desktop based on the latest AMI available in the closest Region: This ensures that the GPU is reserved for specific OpenGL API tasks for the application, and that the performance is not impacted by the desktop environment decorations. Other non-compositing desktop managers (such as XFCE, MATE, etc.) are supported as well. To make the most efficient use of the NVIDIA Tesla M60 framebuffer memory, disable the compositing features of the desktop manager. NVIDIA Grid Driver 6.1 (for the G3 instance family).This stack contains the following software: Use the CentOS 7.5 Server AMI and install the NVIDIA/Xorg/KDE stack to create a fully functioning desktop environment with a max resolution of 16384 x 8640 (that is, 4x4K) at 60 Hz. Except for DCV, this stack is compatible with Debian/Ubuntu distributions. The minimum requirements for this 4K (3840×2160) configuration are as follows: Full-screen redraws may be necessary only in rare cases. One of the benefits of using a multithreaded framebuffer reader is that only the defined block of the rendered desktop that is changing needs to be sent over the network. The GPU framebuffer memory used per session generally limits the number of sessions per managed desktop.Ī smooth reliable experience depends on a low latency and high-bandwidth connection to the EC2 instance hosting the desktop. Each instance can also host multiple users, either in collaborative sessions, or with up to four independent 4K monitors. Depending on the specific G3 instance type selected, multi-GPU managed desktops give additional performance benefits. Provision the backend Linux desktop instance with a 4096×2160 (4K) resolution. Source: from the Amazon offices located in Herndon, VAīandwidth requirements depend on the quality of the desktop experience as well as the desired resolution. Some customers may even prefer to install AWS Direct Connect. I recommend choosing the nearest AWS Region (under 100 ms). Thus latency is an important metric to consider when provisioning this solution. The server captures the framebuffer, which is sent in real time to the client machine over the network. In this configuration, a client machine connects to the provisioned desktop (server) in the cloud. An upcoming followup post details enabling this technology on the Windows platform. Such GPU-backed Linux instances have been used for VFX rendering, computational drug discovery, and computational fluid dynamics (CFD) simulation use cases. This allows clients to take advantage of the server GPU and display the high-resolution content on local thin clients, mobile devices, and low-powered desktops and laptops. The framebuffer objects generated by the GPU are compressed when sent over the network, and decompressed by the local CPU resources. Given the variety of Linux distributions as well as desktop managers, it can be valuable to have a generic solution for provisioning a Linux desktop on Amazon EC2.Ī GPU-backed instance reduces the computational requirements from the client (local) machine, eliminating the need for a local discrete GPU to run graphical workloads. However, many desktop services and applications are better served through a Linux backed instance. Amazon WorkSpaces and Amazon AppStream 2.0 both deliver managed Windows-based machine images with GPU-backed instances.
