Whitepaper: Running Augmented and Virtual Reality Applications on VMware vSphere using NVIDIA CloudXR

· ·

As many of you know by now, I worked on this project with the VXR team at VMware to try to run Augmented and Virtual Reality Applications on VMware vSphere. The white paper demonstrates that, using VMware vSphere backed by NVIDIA Virtual GPU technology, AR/VR applications can be run on a Windows 10 virtual machine with an NVIDIA vGPU, and streamed to a standalone AR/VR device, such as the Oculus Quest or Vive Focus Plus, using NVIDIA’s CloudXR protocol. It was a very interesting project as we had some real challenges I did not expect. I am not going to reveal the outcome of the project and our findings, you will need to read the white paper for that, it will also give you a good understanding of the use cases around these technologies in my opinion. One thing I can reveal right here though is that these workloads are typically graphic intense. I want to share with you one image which in my opinion explains why this is:

Traditional apps/workloads usually run on a single monitor with a frame rate of 30 frames per second. VR applications are presented in a VR headset. A VR headset has a display for both eyes, that doubles the number of megapixels per second immediately, but these displays also expect 72 frames per second or more typically. This is to avoid motion sickness. All of this is described in-depth in the white paper, of course including our findings around GPU utilization when running VR/AR applications using NVIDIA CloudXR, NVIDIA and VMware vGPU on top of VMware vSphere. I hope you enjoy reading the paper as much as I enjoyed the project!

Last day of my Take 3 with the @ProjectVXR team!

· ·

Today is the last day of my Take 3 with the Project VXR team. Ridiculous how fast these 3 months went. It seems like only yesterday that I posted I was going to start this journey of learning more about the world of Spatial Computing and Remote Rendering of VR in particular. If I say so myself, I feel that over the past 3 months I managed to accomplish quite a lot. The last three months I spend figuring out how to virtualize a Virtual Reality application and how to stream the application to a head-mounted display. I tested different solutions in this space, some of which I discussed on my blog in the past months, and I was surprised how smooth it worked, to be honest. If you are interested in this space, my recommendation would be to look into NVIDIA CloudXR in combination with vSphere 6.7 U3 and NVIDIA vGPU technology.

I can’t share all the details just yet, I wrote a white paper, which now needs to go through reviews and copy editing, and hopefully, it will be published soon. I will, however, discuss some of my findings and my experience during some of the upcoming VMUGs I will be presenting at. Hopefully, people will enjoy it and appreciate it.

One thing I would like to do is thank a few people who helped me tremendously in the past few months. First of all, of course, the folks on the Project VXR team, they gave me all the pointers/hints/tips I needed and shared a wealth of knowledge on the topic of spatial computing. I also like to thank Grid Factory, Ben in particular, for the many discussions, emails etc that we had. Of course also NVIDIA for the discussions and help around the lab equipment. Last but not least, I want to thank the VMware OCTO team focussing on Dell Technologies for providing me with a Dell Precision Workstation, and shipping it out literally within a day or two. Much appreciated everyone!

Now it is time to get back to reality.
