Nvidia, Citrix crank up virtual desktop delivery - carrdidellp
Improvements to Nvidia's virtualization technology are aimed at turning graphics processors into a more important resource in data centers and could speed deployment of virtual desktops and delivery of data over the cloud.
The graphics company Tuesday announced improvements to its VGX technology, which virtualizes the GPU and makes it a resource that can be shared with CPUs and memory in servers. Hardware and software improvements to VGX will permit a graphics board to deliver multiple virtual desktops. Antecedently, VGX could hand over only one virtual machine per graphics board.
Nvidia Virtualization enables efficient use of server resources in a distributed computing environment and GPUs could help cut electric bills through fast delivery of practical desktops. GPUs are considered quicker than CPUs in some cases and are used in some of the world's quickest computers for complex calculations, atomic number 3 easily as by Web browsers for quicker graphics rendering. Virtualizing art processors could enable servers to deport games over the cloud and get superior resources free to remote users.
Nvidia worked with virtualization society Citrix to clear improvements at the hypervisor, number one wood and ironware levels, said Sanford Russell, director of Gridiron selling at Nvidia. The VGX improvements testament work only with Citrix's Xen products, including XenServer and XenApp. Ultimately, Nvidia hopes to add the VGX improvements to virtualization technologies from VMware and Microsoft, but Russell could not provide a special date on when that Crataegus oxycantha happen.
Graphics processors from Nvidia and Advanced Micro Devices are already being used for virtualization, with server makers Dingle, Hewlett-Packard and IBM oblation servers designed for the hyperscale environs. But the realistic desktop user Roger Huntington Sessions were shorthanded by limited resources.
The updates to VGX will deploy virtual desktops running full Windows 7 and users will be competent to run along multiple applications in each session, Russell said.
"What we are delivering is a true PC see," Russell aforesaid.
The Nvidia Grid K1 art board, which has four graphics processors and 16GB of DDR3 store, will be able to plump for upbound to 32 practical machines simultaneously. The Control grid Godwin Austen board, which has two graphics processors and 8GB of GDDR5 memory, bequeath be competent to support up to eight VMs. The virtual machines will be able to tap into on-board DirectX 11 put up to boost multimedia system performance.
The graphics processors are based on Nvidia's latest Kepler architecture and the boards have independent schedulers and memory management units to handle virtual-machine deployment. VGX enables GPUs to skip CPU cycles and to directly deploy and superintend essential machines.
Virtualization is key in version cloud services via GPUs, but the VGX improvements could be ahead of their fourth dimension, aforementioned Jim McGregor, principal psychoanalyst at Tirias Research.
"This is overkill for what people deman and non everyone volition make usance of the resource," McGregor said.
Nvidia is offering a untested set of server products and graphics boards under the marque Grid as the company connects GPUs to the growing number of virtualization and cloud deployments. Nvidia offers the Grid Optical Computing Appliance (VCA), which does server-side processing of multimedia and other applications for cloud-based livery to virtual desktops on thin clients, PCs or tablets. The society has likewise partnered with host makers IBM and Dell to offer GPU-rich Grid servers. Nvidia also said Lake herring will showtime shipping the VGX Grid server called UCS C240 M3 start this month.
But GPUs are already becoming more practical in servers with gaming departure online and more applications being written using parallel programming tools like OpenCL and CUDA, McGregor said.
Servers deal with different types of workloads and GPUs still call for CPUs to function in distributed computation environments. Book of instructions to the GPU are funnelled through the CPU.
"Using [GPUs] as a processor computer architecture in the corrupt is no different than using a [CPU] or bespoke processor," McGregor said.
Nvidia and AMD are artful chips and establishing active standards that make GPUs a more accessible resource. The AMD-led HSA (Heterogeneous Organization Architecture) Initiation has introduced a uniform memory computer architecture called HUMA, which will make different memory types accessible to all processors. Nvidia's next graphics processor called J. C. Maxwell, which is due next year, will too pool unitedly CPU and GPU memory.
Technologies like VGX make GPUs Sir Thomas More relevant in host environments, McGregor said.
"It has a dry road map," McGregor said.
