The Standard Agent for Linux provides support for PCoIP Ultra, the latest protocol enhancements from Teradici. PCoIP Ultra is optimized for truly lossless support with bit-exact color accuracy and preservation of content detail at the highest frame rates.
PCoIP Ultra protocol enhancements propels our industry-recognized performance into the future of remote computing, with faster, more interactive experience for users of remote workstations working with high-resolution content.
PCoIP Ultra enhancements are disabled by default. You must enable them manually.
PCoIP Ultra is appropriate for specific use cases
For most users, the default PCoIP protocol will provide the best possible experience. Carefully review the recommended use cases in the next section to determine whether you should enable it.
For additional detail on PCoIP Ultra technical requirements for various use cases and troubleshooting steps, refer to KB 2109: PCoIP Ultra Troubleshooting.
When to Enable PCoIP Ultra¶
PCoIP Ultra provides efficient scaling across multicore CPUs, leveraging AVX2 instruction sets. Appropriate for users that require CPU-optimized delivery of 4K UHD, high-framerate video playback and build-to-lossless color accuracy.
For all other scenarios, Teradici recommends that you leave PCoIP Ultra disabled.
To take advantage of PCoIP Ultra, you need:
A PCoIP agent (any type), 21.03 or later
A PCoIP Software Client (any type), 21.03 or later
PCoIP Tera2 Zero Clients are not supported
PCoIP Ultra is supported by PCoIP Software Clients only. PCoIP Tera2 Zero Clients cannot use PCoIP Ultra.
The CPUs on both the agent and the client machines must support the AVX2 instruction set.
Enabling PCoIP Ultra¶
To enable PCoIP Ultra features, edit the pcoip-agent.conf file and set the
pcoip.ultra configuration setting as required:
- 1 To turn on PCoIP Ultra CPU Offload. CPU offload requires CPU support for the AVX2 instruction set on both the remote host and client. The PCoIP Zero client is not supported. CPU offload is recommended for 4K UHD resolutions with video playback requirements of 30 fps (or more), and the highest possible image quality and color accuracy.
All PCoIP Ultra settings take effect on the next PCoIP session. No configuration is required on the PCoIP Software Client.
Turning PCoIP Ultra off
To disable PCoIP Ultra and use the default PCoIP experience instead, set
pcoip.ultra to 0.
