FastX by StarNet Communications is a remote Linux desktop and application delivery platform designed for HPC environments where engineers sit on Windows or macOS workstations but compute on large Linux clusters and supercomputers. It provides graphical access to Linux desktops and individual applications over the network, translating traditional X11 traffic into an efficient protocol that can be consumed through native clients or a browser. https://www.starnet.com/fastx

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

Instead of requiring custom client installs everywhere, FastX exposes Linux desktops directly in a standard web browser using HTTPS, so any device with Chrome, Edge, Firefox or Safari can connect securely to a FastX server. The same backend can also serve native clients for Windows, macOS and Linux, while handling session persistence, reconnect, and access control in multi-user, multi-cluster deployments
In the interview, StarNet explains how this approach is used by universities, national labs, aerospace and defense organizations that run heavy visualization and CAE workloads on shared HPC clusters. Instead of pushing users toward pure command-line workflows, FastX lets them run interactive tools for seismic interpretation, scientific visualization or rich IDEs with point-and-click interfaces, even when the compute nodes sit in remote, highly secured data centers
Recorded at the SC25 Supercomputing conference in St. Louis, the demo shows a live FastX session from a server in San Jose running across a congested show network. The focus is on maintaining usable latency and frame rates over long distances, while still respecting strict IT policies around authentication, cluster access, and security domains. Many sites deploy FastX under campus-wide or site-wide licensing so researchers can attach to the same supercomputing infrastructure from labs, offices or home.
StarNet also highlights its work on supporting Wayland-based environments through the browser, aligning FastX with the ongoing transition away from X11 in many Linux distributions while still serving legacy X11-based applications. The result is a remote display layer that tries to bridge old and new Linux graphics stacks for HPC, giving system administrators a managed way to expose interactive GUI access across the planet without forcing users to abandon their existing tools
