No, but with many other heavy applications. It's all about sizing. What hardware do you use? And is server 2016 baremetal or a hypervisor in between? To be honest, a P2000 is a low end to midrange card. For multi user workloads on graphics intensive applications you need other cards like T4 or RTX6000.

Hi rody, i have done some cad projects... so for me its clear, but here i‘m confused, because the vendor has done the sizing and delivers the server.... but now the customer asks me to get out of that hell .... so for that i need a real world comparison from anyone who ever go through that
k
It doesn't look like Elekta Monaco is very GPU intensive, it just displays radiology images. Sounds more like your Citrix setup is not properly done..
On the other hand, like Rody says, it's probably not a good idea to share a P2000 with multiple users.. But I think the rest of the hardware is also going to be important. What's the specifications of the server?
Also important to know what exactly is not "performing" well. Image quality? Frame rate?
c
Every host has 2 xeon gold cpu‘s with 3.2 ghz. When anyone zooming in / out, the cpu goes up to 100% and its stucks
,,citrix setup is not properly done“ -> elekta delivers the server with an own preinstalled site setup ;) .... so rds an directly connected screen to host doesn‘t change anything
k
So sounds like Citrix is not using the GPU to do the displaying/encoding.
And when/if the HDX settings are set to something like "Build to Lossless", which would make sense in this case, since it's radiology images and you'd want them to be crystal clear, that's not going to work very well without GPU encoding and HDX 3D Pro running properly.
I think it would make sense if you run Citrix's HDX Monitor and do an export of the settings so Rody or I can take a look at them.
r
Or even better, use RDAnalyzer so we can see all the details.

Or that 😄
That would be easier indeed, good point Rody.
c
Okay, will do it and come back on that
here the screenshot from rdpro
here the policy provided by the vendor
r
Hmm, disable that and set the graphics to: - Allow Visually Lossless: Enabled - Visual Quality: Build to Lossless - Allow Hardware Encoding: Enabled - use video codec: For the Entire screen This will do YUV444 with Build to Lossless for windows endpoints, all other will do YUV420. Build to Lossless is in remote scenarios much better than Always lossless as it will use H264 for moving images and will build it to a lossless image when movement stops
Here is a comparison I made with a 4Mbit connection

Hi @Rody Kossen, just provided the original policy. Already set it like you said. The Problem is here that the cpu drops to 100% when the users scrolling in monaco
k
Then (as said before) the GPU is probably not doing the encoding. (Hardware Encoding: Enabled)
It should mention that in the "Detected settings" part of the RDAnalyzer
Alternatively you can install HDXMonitor to verify: https://support.citrix.com/article/CTX135817

Will confirm this week with an PoC with a new server with a t4
