![]() ![]() However rendering is just one of a number of tasks and computational loads that performs really well on a GPU. Typically these rendering tasks often involved implementing libraries that could handle lots of vector data, facets and manipulate them (think triangles!). Standard APIs and libraries such as OpenGL and DirectX were specifically developed to make developing rendering applications that made writing code that could be parallelised easy, exploiting the potential of the GPU. The “G” in GPU stands for Graphics because this has been historically where this type of processor was found to be extremely useful. GPUs on the other hand can have hundreds or thousands of smaller cores designed for parallel performance. CPUs have few cores optimized for serial processing. If NVIDIA enable CUDA support for vGPU as they have for GPU passthrough, then Citrix will automatically gain support.ĬUDAis very interesting. OpenGL and CUDA support is also provided by the GPU vendors such as NVIDIA. ![]() We have deliberately avoided using synthetic drivers to avoid the serious problems encountered by other vendors on benchmarks such as Redwa圓D. This ensures that the support for DirectX and OpenGL is always up to date and available as for physical servers, this white paper from HP details how support on other hypervisors significantly lags Citrix. ![]() All of Citrix’s GPU technologies rely on GPU vendors own drivers to avoid an additional layer of support and certification. So it seemed the perfect time to clarify the position.įor Citrix products, Vendor Drivers provide the support for DirectX, OpenGL, OpenCL and CUDA. Additionally there was an error in a whitepaper that stated vGPU currently supported CUDA which isn’t yet true. During the EMEA masterclass several questions arose on CUDA support across many of our different GPU technologies. We always run a live Q&A on these webinars with a team of real software engineers, product managers and solutions experts and afterwards review the quality of our answers and see what Citrix should do long term to clarify those questions that recur. Please note this blog was written in April 2014 and you are reading it in the future you should check the support matrix for possible further improvements with NVIDIA and Citrix.Ī few months ago we ran an interactive masterclass for XenServer and XenDesktop customers featuring storage configuration software from NetApp and also NVIDIA GRID vGPU (true hardware GPU sharing) for XenDesktop with HDX 3D Pro.
