NVIDIA GRID: Citrix HDX adds support for Relative and Absolute Mouse Modes to Linux Receiver

Update: 14th September 2016 – Receiver For Windows 4.5 released today now adds support for Windows in addition to Linux!

Just a quick blog to highlight the availability on the Citrix HDX/ICA protocol of a feature enabling Relative Mouse mode. This is a particularly interesting for many NVIDIA GRID vGPU and graphical users as it enables better behavior of certain gaming like applications, particularly those favoured in federal simulations (battle and flight-simulators) e.g Bohemia Simulations VBS 2 & 3. Before on certain application without using an addition gamepad device the mouse could behave strangely ending up with the user pointing their barrel at the ground or sky.

Benchmarking virtualized NVIDIA GRID GPU cards using HPC methodologies! Don’t wear shiny green high-heels in the farmyard!

I’ve been cc:d on a clutch of strange enquiries recently where people are trying to evaluate the NVIDIA GRID GPU cards using HPC (High-performance computing) methods, benchmarks and comparisons. Hypervisors aren’t usually fully compatible with HPC application architecture and as such, although the newest NVIDIA Tesla cards (M60/M6) can be repurposed between a “compute mode” and a specialist “graphics” mode is provided for virtualized graphics designed with hypervisors and graphical application architecture in mind.

The previous (Kepler) generation of NVIDIAGPUs for virtualized graphics (GRID K1/K2) are designed solely for grahical workloads. Continue reading “Benchmarking virtualized NVIDIA GRID GPU cards using HPC methodologies! Don’t wear shiny green high-heels in the farmyard!”

NVIDIA M60 GPUs – how they support CUDA, OpenCL and compute in “graphics” mode

cuda_openclYesterday I wrote a blog about how to configure the M60 / M6 NVIDIA GPU boards for use for “graphics” mode or “compute” mode and how they were designed for different use cases such as VDI accelerated graphics and HPC (high-performance compute) respectively.

This has led to some questions as to whether “graphics” supports compute and CUDA like technologies. The answer is yes! Continue reading “NVIDIA M60 GPUs – how they support CUDA, OpenCL and compute in “graphics” mode”

Mode switching on NVIDIA M60 (GRID 2.0) cards – modeswitch tool

modeswitchingUpdate (24th Feb 2016): Jason Southern has published an overview and how-to-guide on this tool: https://www.youtube.com/watch?v=VAQhiNNFXxQ&feature=youtu.be

 

I had an enquiry this week asking what the “modeswitch tool” is and when a user should use it. Basically a GRID 1.0 K1/K2 user had been to a demo of the new GRID 2.0 M60 GPUs. As he hadn’t got M60 boards yet he didn’t have the tool and hadn’t downloaded it (so hadn’t read the very comprehensive documentation that comes with it explain when and why to use it) but he’d remembered some information from the demo and was trying to extrapolate that to his GRID 1.0 K1/K2 cards.

Scalability benchmarking – XenDesktop 7.7 and Windows 7

SSSFellerWhen I worked at Citrix one of my now colleagues at NVIDIA (Jason Southern) came to us with a proposal and PoC (you can read the blogs about that experiment, here) for us to implement templates to assist users to configure and optimize HDX graphics for XenDesktop and XenApp (Template details – here). XenDesktop/XenApp 7.6 FP3 saw the release of these templates which allowed users to configure their graphics for the specific needs of their users (user experience vs. server scalability) and network conditions (WAN/limited bandwidth etc.).

HDX: Enhanced Support for 3D and CAD Cursors with Citrix XenDesktop/XenApp 7.6 FP3

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.
