A CAD Bunny's Big Adventure Through Virtualisation… frolicking with GPUs along the way – by Rachel Berry
The TCP implementation within Citrix HDX/ICA protocol used by XenDesktop and XenApp and also Citrix Netscaler is pretty Vanilla to the original TCP/IP standards and definition and the out-of-the-box configuration usually does a good job on LAN. However, for WAN scenarios particularly with higher latencies and certain kinds of data (file transfers), Citrix deployments can benefit greatly from some tuning.

I was so pleased to receive the below invitation to this event coming up in April from Roy Textor who runs DCUG (Deutschsprachige Citrix User Group / German-speaking Citrix User Group). It’s nearly two years since I blogged about the birth of this group, you can read that here. In the time since then Roy has run dozens of user group meetings all over Germany (I’d love you to comment on this blog if you have attended) and the community is going from strength to strength.

A wrote a blog a while ago (read it here) about how although the Citrix Studio Console interface shows every policy for every graphics mode, most modern graphics modes need very little configuration and are affected by a few policies only.

In a past life I was a kernel engineer on Parasolid the numerical heart within many top CAD applications such Ansys Workbench, Dassault Solidworks, Siemens NX and Solid Edge, Bentley, Nemetscheck, Missler Top Solid; I lived, breathed and obsessed about CAD workflows, how users construct parts and use CAD applications. Now I’m in Cloud computing and VDI, I still get to work with CAD applications but am working in an industry where for many other than the customer – a CAD application is just another VDI or virtualised app or workload.
One of our really experienced experts has just done a blog on some evaluation he did on Citrix’s hot new graphics mode: http://trentent.blogspot.ca/2015/09/performance-differences-in-citrix-hdx.html. Now this guy knows what he is doing but I’m a little worried others might not fully understand what has been done or the implications for the results. Trent did some tests flipping the encoder via a registry key. We do not encourage users to play with registry keys, occasionally they can prove useful to tweak a system, but really if that is being done we should be exposing the control via properly documented policies.
Last week I had a twitter user make comment that implied the reason some of our recent thinwire enhancements have happened is because some of the HDX development and product management team are in the UK! Stefan made this comment
After seeing a fellow tweeter struggling to get a decent mobile signal in central London, supposedly one of the world’s most developed cities! Continue reading “When less is more! Avoiding excessive web content!… I hate hi-res stock photography!”
Citrix XenDesktop/XenApp 7.6 FP3 has introduced enhanced architecture to support both 24-bit and 32-bit advanced cursors. Historically remoting protocols have supported simpler cursors but with an increase in the use of complex and larger cursors for complex CAD and 3D applications, Citrix has introduced a new architecture to support such cursors on-going.
I’ve blogged before about how H.264 technologies can inherently have artefacts associated with them (read here). Particularly CAD hidden-line/wireframe lines that are near parallel can show a fading in colour or seem “less sharp”
Jason Southern from NVIDIA released a video this week describing how to measure and understand the framebuffer usage for technologies used by Citrix XenApp, XenDesktop and HDX, the video is available here.

Back in May 2015, at Citrix’s Synergy 2015, I was involved with an HDX demo at Citrix Synergy 2015, the remit was pretty simple – to show really good HDX 3D Pro frame rates, good enough to satisfy gamers, on low-cost hardware using ONLY existing, shipping-today, fully-supported production ready products. We also want to show that HDX 3D Pro can run really w Continue reading “Did I really see a $165 Thin Client doing 55fps+ with Borderlands 2 with HDX 3D Pro, Citrix XenDesktop?”
