Taipei, November 18, 2011: Zillians, a leading cloud solution provider specializing in high performance computing, GPU virtualization middleware and massive multi-player online game (MMOG) platforms today announced the availability of vGPU – the world’s first commercial virtualization solution for decoupling GPU hardware from software. Traditionally, physical GPUs must reside on the same machine running GPU code. This severely hampers GPU cloud deployment due to the difficulty of dynamic GPU provisioning. With vGPU technology, bulky hardware is no longer a limiting factor. vGPU introduces a thin, transparent RPC layer between local application and remote GPU, enabling existing GPU software to run without any modification on a remote GPU resource.

Utilizing Mellanox Technologies InfiniBand RDMA I/O solutions and NVDIA GPUDirect technology, Zillians vGPU achieved peak data transfer rates between application and GPU hardware. This opens the door to a broader range of GPU applications that can take advantage of virtualized GPU resources, and also a boon for service providers or cloud operators looking to deploy next generation cloud services based on scalable GPU and Infiniband technologies. As interest in GPU-based HPC clusters continues to grow, vGPU represents a critical enabler for systems to realize resource sharing and improve system utilization across a variety of application domains.

“We are excited to collaborate with Zillians to provide new capabilities for high-performance and massive multi-player online gaming cloud platforms,” said Gilad Shainer, Senior Director, Market Development at Mellanox Technologies. “Mellanox InfiniBand I/O solutions with native RDMA support and GPU acceleration provide the essential technology for Zillians’ innovative vGPU solution.”

Availability

Zillians vGPU is now available for early evaluation request. Version 1.0 featuring support for NVIDIA CUDA 4.0 runtime and driver APIs will be released by the end of 2011. Version 2.0 featuring further support for OpenCL 1.1 is scheduled for release in 2012 Q1. To learn more, please visit www.zillians.com/vgpu.

Computer graphics is hard work. Behind the images you see in games and movies, or while editing photos or video, some serious processing is taking place. All the processing power you can muster is needed to push and polish pixels. And this task is only going to get more demanding as these applications get more sophisticated. Graphics Processing Units (GPUs), which do the heavy lifting in computer graphics, range greatly in size, price and performance. They span from tiny cores inside an ARM processor (such as Nvidia’s Tegra or Qualcomm’s Snapdragon), to graphics integrated within an X86 processor (such as AMD’s Fusion, Intel’s Sandy Bridge), to a standalone discrete device, or dGPU (such as AMD’s Radeon, or Nvidia’s GeForce).

The amount of available memory on modern GPUs is relatively small.  Scenes for feature film rendering and visualization have large geometric complexity and can easily contain millions of polygons and a large number of texture maps and other data attributes. CentiLeo presents an interactive out-of-core ray tracing engine running on the single desktop GPU. The system is built around a virtual memory manager. A novel ray intersection algorithm built around an acceleration structure, cached on the GPU, loads needed data on-demand using page swapping. The ray tracing engine is used to implement a variety of rendering and light transport algorithms. The system is implemented using CUDA and runs on a single NVIDIA GTX 480.

A demo video presents an interactive path tracer rendering the massive 400-million-polygon Boeing 777. There will be a talk on SIGGRAPH 2011 about this work: “Out-of-Core GPU Ray Tracing of Complex Scenes“, by Kirill Garanzha, Simon Premoze, and Alexander Bely. Kirill also has a paper at High Performance Graphics this weekend.
