Google Chrome 45.x Blocks GPU Acceleration for WebGL, Direct2D, DirectWrite with Citrix XenApp on Windows 2008R2/2012/2012R2

Solution: Google Chrome 45.x Blocks GPU Acceleration for WebGL, Direct2D, DirectWrite with Citrix XenApp on Windows 2008R2/2012/2012R2

Google Chrome v. 45 have changed their behaviour of their web browser, so they are blacklisting GPUs, which means hardware acceleration is disabled by default in a Remote session this behaviour is seen in Microsoft RDS with RemoteFX, Citrix XenApp 6.5 -> 7.6 with vGPU/GPU pass-through. Behaviour is also seen on Linux environments with Google Chrome.

Issue highlightet in a Citrix XenApp 7.6 (2008R2/2012/2012R2) with GPU

Open Google Chrome and type in chrome://gpu and then you will see if your RDS/XenApp with a GPU is working or not.
With Google Chrome v 45 the default behaviour is now that Google choose to disabling the GPU.

Google Chrome experience with a GPU (Citrix XenDesktop vs Citrix XenApp)

above picture confirms the GPU is not enabled in Google Chrome with RDS/XenApp

interesting is that Multiple Raster Threads in Win7 with a GPU is disable… why lets find out.

This is properly because you haven’t configured the CPU correctly in the hypervisor for the virtual machine.
* hint I did on purpose so you can understand it can be complex to troubleshoot if you don’t configure your environment correctly.

best practices with HDX 3D Pro is 4 vCPU and in XenServer 6.5 you configure it 2:2

Then Multiple Raster Threads works in Win7 after you changed the configuration of the CPU on the Win7 vm.

browser - chrome win7 cpu fix

below picture confirms the GPU is not enabled in Google Chrome with RDS/XenApp in Server 2012R2

Now we have validated that the GPU is blacklisted in RDS/XA with a GPU, lets see if we can fix this.

Performance with a WebGL web app in Google Chrome

CPU is very high when the Google Chrome is running the WebGL application. This is because its using the CPU to do software rasterize of the GPU and this makes your user able to run a webgl application without a GPU, but wait. We actually have a GPU in our RDS/XA server now, why is this not offloading the CPU, thats because Google desided to turn off GPU and blacklist them.

Solution

Edit Google Chrome link and after the chrome.exe add
–ignore-gpu-blacklist
Open Google Chrome and run chrome://gpu in the browser
Check if Hardware acceleration is now working for all functions in Google Chrome

GPU hardware acceleration is now working in RDS/XA with a GPU in Google Chrome and CPU is now offloaded to the GPU as you can see in the below picture.

NVIDIA GRID 2.0

NVIDIA have released the next generation of GRID 2.0. GRID 2.0 is based on the Maxwell architecture and the GRID 1.0 (K1/K2) was based on the Kepler architecture. I have been working with the GRID 1.0 technology since 2012 and it have matured alot in its 2 years of history. When the K1/K2 was released they was first working with GPU pass-through and then vGPU got introduced and you could virtualize the GPUs and increase density, which people wanted. Citrix was with their hypervisor the first company that supported NVIDIA GRID 1.0 and they was also the first company integrating vGPU into their Citrix Studio, so companies could easier provisioning machines with either MCS technology or PVS technology. VMware supported GRID 1.0 vGPU technology in 2015 in their hypervisor VMware vSphere 6.0 and fully integrated with their EUC stack VMware View, so companies can fully provisioning machines. The great thing about GRID 2.0 is that there is no need for a conversation when to choose either a K1 or a K2, if you required GPU compute or GPU framebuffer, M60 are being added to the tope end of the range and bringing 2x the performance, and if you have bladeserver’s, you can add the powerfull vGPU technology into the bladeserver’s with the M6.

Please notice that M6 will 0nly be supporting newer architecture of vendors not old platforms.

Maxwell architecture

Maxwell architecture is the new architecture of GPUs and a powerful GPU you might know is the Titan X

New GPUs GRID 2.0 and specifications

In GRID 2.0 NVIDIA now have a GPU for blade servers a MXM single socket, High-end GPU called M6

In GRID 2.0 NVIDIA replaces K1/K2 with the new PCIe 3.0 Dual Socket, Dual High-end GPU called M60
The M60 delivers 4096 CUDA or compute and 16GB GDDR5 memory/framebuffer

The M60 has 6x the h.264 encoders of the K2, and also Maxwell supports 4:4:4 chroma sub sampling, which is great news for encoders.

Certified GRID 2.0 servers

M6 have following servers supported:

M60 have following servers supported:

vGPU software editions and license

NVIDIA GRID 2.0 software is available in three editions that deliver accelerated virtual desktops to support the needs of your users. These editions include Virtual PC, Virtual Workstation, and Virtual Workstation Extended. GRID perpetual licenses are sold by Concurrent User (CCU).

NVIDIA GRID 2.0 (CCU) stands for ConCurrent User. So basically, per running VM as regardless of whether the user is connected to the VM or not, the VM is connected to the GPU and so consumes a license

NVIDIA GRID 2.0 software is much more than a “driver”. While the software package does include a guest driver for Windows and Linux, it also includes the NVIDIA GRID vGPU manager for VMware vSphere and Citrix XenServer, as well as the license server and M6/M60 mode switching utility.

NVIDIA Tesla M6 and M60 profiles are specific to the M6 and M60. There will be similar profiles as to what NVIDIA had on K1 and K2 (512 MB through 4 GB), all with twice the number of users on M6/ M60 compared to K1/K2. Plus, there is an additional 8 GB profile on M6/M60 which also adds support for CUDA, which wasn’t available on K1/K2.

NVIDIA GRID 2.0 is Maxwell only. If you are an existing customer K1/K2 are unchanged and will remain as a parallel option.

The NVIDIA GRID 2.0 solution

Summary

GA of NVIDIA GRID 2.0 (M60 and M6) will be 15 September 2015.

To get NVIDIA GRID 2.0 if you are a Citrix customer you need:
Server hardware that supports NVIDIA GRID 2.0 +NVIDIA GPU M60 or M6 + NVIDIA vGPU Software license + Citrix XenDesktop or XenApp License (XenServer is included in XD/XA licenses)

To get NVIDIA GRID 2.0 if you are a VMware customer you need:
Server hardware that supports NVIDIA GRID 2.0 +NVIDIA GPU M60 or M6 + NVIDIA vGPU Software license + VMware Horizon license (Horizon includes vSphere for Desktop)

If you are a Citrix customer that wants to run on VMware vSphere you need:

Server hardware that supports NVIDIA GRID 2.0 + NVIDIA GPU M60 or M6 + NVIDIA vGPU Software license + Citrix XenDesktop or XenApp License + VMware vSphere Enterprise Plus license or vSphere for Desktop license

Citrix XenDesktop 7.1

Citrix XenDesktop 7.1 is now finally released and vGPU is now in the product and build in with MCS, very very cool. You can configure GPU pass-through with any GPU card or vGPU profiles with NVIDIA GRID, the brilliant thing about this its now build in to the product, you only have to choose a GPU profile and XenDesktop takes care of the High Availability with XenServer and find the resources that free and connects the GPU to the Virtual Machine. Microsoft have just released Windows 8.1 and Server 2012R2 and in this release of Citrix XenDesktop 7.1, Citrix are supporting Microsoft newest Operating System Platforms.

One of the things that have been fixed in the XenDesktop 7.1 Virtual Delivery Agent is following:

With HDX 3D Pro enabled, the NVIDIA card might not support certain resolutions. This enhancement introduces support of up to 2560×1600 pixel resolutions.
With HDX 3D Pro enabled, client connections to a XenDesktop 5.6 VDA do not support resolutions beyond 1900×1200 pixels. This enhancement introduces support for a wide range of additional resolution ratios, including:
- 1920×1200
- 2048×1152
- 2560×1440
- 2560×1600

What’s new in XenDesktop 7.1

GPU — The Graphical Processing Unit (GPU) capabilities feature provides graphics virtualization, offering a superior experience for users who use graphic-intensive applications and often manipulate 3-D models. The GPU feature also can improve the graphics experience for a large number of users. Administrators can evaluate workflows for the creation of GPU-capable connections and machine catalogs created with an MCS-provisioned master image. If problems are encountered, then Administrators may need to manually create the machines.

When you install Citrix XenDesktop 7.1 on the Controller, you can now choose a GPU type and group which its getting from XenServer.

If you have NVIDIA GRID with XenServer, XenDesktop 7.1 takes care of creating a GPU type attached to the GPU group.

in above example I am choosing a vGPU type: K140Q. It have 960MB video RAM per VM)

If you have 1 GRID K1 card and choose a K140Q type, you can have maximum 16 virtual machines assigned to this card. If you have 2 GRID K1 and choose K140Q type, then you can have 32 virtual machines assigned to the GROUP K1, and XenDesktop 7.1/XenServer vGPU takes care of the HA of GPU assignment.

Look at below chart to get an understanding of which vGPU types you can choose in XenDesktop 7.1 with NVIDIA GRID K1 & K2.

Read my blogpost about vGPU profiles

The above numbers are from NVIDIA but the vGPU types Citrix have defined in XenDesktop 7.1 are following:

for NVIDIA GRID K1 vGPU options:

GRID K100 (256B video RAM per VM)
GRID K140Q (960MB video RAM per VM)
Passthrough – GK107 GL GRID K1

for NVIDIA GRID K2 vGPU options:

GRID K260Q (1920MB video RAM per VM)
GRID K240Q (960MB video RAM per VM)
GRID K200 (256MB video RAM per VM)
Passthrough – GK104GL

Windows Server 2012 R2 and Windows 8.1 support — Deliver a high-definition user experience on Windows 8.1 virtual desktops and physical machines. HDX 3D Pro has also been upgraded to support Windows 8.1.

Upgrade XenDesktop 7 components to 7.1

When you run the installer AutoSelect, the wizard checks whether certain Site components (such as the Delivery Controllers, Director, and VDAs), need to be upgraded. If you opt not to upgrade some components during this process, when you run Studio, it performs a component check and notifies you when components need to be upgraded. You cannot proceed to manage your Site until you upgrade these components.

Upgrade Site with components deployed on different machines

The following figure shows the high-level processes involved when upgrading a XenDesktop 7 to XenDesktop 7.1 in which Studio components are deployed on different machines.

Perform the upgrade procedures in the following order.

Check the licenses

Make sure that your Subscription Advantage date for licenses is no earlier than 2013.0522.

Upgrade StoreFront

If StoreFront is deployed on a separate machine, follow the steps described in Upgrade core components from eDocs

Upgrade Director

If Director is deployed on a separate machine, follow the steps described in Upgrade core components from eDocs

Upgrade Provisioning Services

If you are using Provisioning Services, follow the procedures described in Upgrading Provisioning Services from eDocs

Upgrade the Virtual Delivery Agent

For Remote PC Access deployments, Citrix recommends that you upgrade a VDA in a remote PC using a command-line method. For detailed information, see Install using the command line.

Log on to the server using a local administrator account and run the installer by inserting the media or mounting the ISO drive for this release, and double-clickingAutoSelect.
On the Welcome page, click Start. The wizard detects what components need to be upgraded and displays the Upgrade options page, activating the components you can upgrade.
On the Upgrade options page, select:
- Virtual Delivery Agent for Windows Desktop OS for Desktop OS, and earlier XenDesktop versions
- Virtual Delivery Agent for Windows Server OS for Server OS
On the Firewall page review the default ports and configure firewall rules.
On the Summary review the prerequisites to be installed and the components to be upgraded then click Upgrade.
On the Finish Upgrade page one of the following messages appears upon completion:
- Success — Upgrade successful appears when the upgrade completes without errors.
- Failed — The Upgrade failed appears with a list of failed components. Click Why did this fail to review what you must do to fix the problem. Other components that installed successfully are retained; you do not need to reinstall them.
Click Finish to complete the upgrade.

Upgrade Delivery Controllers

Citrix recommends that you upgrade Delivery Controllers as follows:

Upgrade half of your Site’s Delivery Controllers.
Use the upgraded version of Studio to perform the Site upgrade as described in Upgrade core components.
Upgrade your remaining Delivery Controllers.

Upgrade Databases using Studio

Use Studio to upgrade the Database.

Automatically upgrade Databases

Start Studio. The wizard detects what components need to be upgraded and displays the Mandatory upgrade page.
Select Start the Site upgrade automatically.
At the prompt, select I am ready to upgrade.The wizard displays the upgrade progress. After the upgrade completes, the wizard performs tests. This takes several minutes.
At the Site Upgrade Complete window, you can optionally view a data migration report and then click Finish.
At the Upgrade successful page, click Finish upgrade and return to the Site overview.

Manually upgrade Databases

To minimize Site down time when performing a manual upgrade, it is important that the XenDesktop Administrator closely coordinates with the Database Administrator. This process requires that you run a script that temporarily disables Xendesktop Services while the manual upgrade scripts are run by the Database Administrator using a preferred tool (for example, SQL Server Management Studio). Ideally, immediately after these scripts complete, the XenDesktop Administrator should enable XenDesktop Services and complete the upgrade using Studio.

Manual upgrade requires:

Backing up the databases
Running the generated scripts in the following order:

DisableServices.ps1 — PowerShell script to be run by the XenDesktop administrator on an XenDesktop Controller.
UpgradeSiteDatabase.sql — SQL script run where the Site databases resides
UpgradeMonitorDatabase.sql — SQL script run where the Monitor databases resides.
UpgradeLoggingDatabase.sql — SQL script run where the Logging database resides.
Note: You should only run this script if the Logging database changes. For example, run it after applying a hotfix.
EnableServices.ps1 — PowerShell script to be run by the XenDesktop administrator on an XenDesktop Controller.

To upgrade manually

Start Studio. The wizard detects what components need to be upgraded and displays the Mandatory upgrade page.
Select Manually upgrade this site.
The wizard checks for License Server compatibility. Make sure your License Server and license files are compatible with XenDesktop 7.1. Select the confirmation check box and click Continue.
The wizard prompts you to backup the Database. When you have done so, select the confirmation check box and click Continue.
- The wizard generates the manual upgrade scripts that you must run and displays them in a window
- The Mandatory Upgrade page changes to display a checklist of the manual upgrade steps
Make sure you have completed the checklist tasks and click Finish upgrade and return to Common Tasks.

Upgrade core components

The installer automatically upgrades core components such as Delivery Controllers, Studio, and Director if they were previously installed.

Log on to the server using a local administrator account and run the installer by inserting the media or mounting the ISO drive for this release, and double-clickingAutoSelect.
On the Welcome page, click Start. The wizard detects what components need to be upgraded and displays the Upgrade options page, activating the components you can upgrade.
Click Delivery Controller.
Accept the license agreement.
Review the upgrade steps, click I’m ready to continue and click Next.
On the Core Components page review the components available for upgrade.
On the Firewall page review the default ports and configure firewall rules.
