Curtiss-Wright Controls Launches Industry's First Fermi Architecture NVIDIA® GPGPU 3U OpenVPX™ Engine

ASHBURN, VA--(Marketwire - Dec 8, 2011) - Curtiss-Wright Controls Embedded Computing (CWCEC), a business group of Curtiss-Wright Controls and a leading designer and manufacturer of commercial off-the-shelf (COTS) VME, VPX, OpenVPX™ and CompactPCI products for the rugged deployed aerospace and defense market, has announced its first 3U OpenVPX general purpose graphics processing unit (GPGPU)- multi-core engine, the VPX3-491 GPU Application Accelerator. The small form factor VPX3-491 features an NVIDIA® GPU based on the NVIDIA Fermi architecture with 240 CUDA™ cores. Integrated into subsystem, the VPX3-491 functions as a co-processor attached to a host Intel®-processor board and takes advantage of the new PCIe Expansion Plane definitions in the VITA 65 OpenVPX standard to provide off the shelf backplane support for high-speed interconnection between pairs of SBC/GPU. The combination of 2nd Generation Intel processors, gen2 PCI Express interconnect and 240 NVIDIA CUDA cores raises the performance bar for compact systems for demanding military digital signal processing (DSP) applications such as C4ISR, EO/IR, and SatCom.

The VPX3-491, combined with Curtiss-Wright's VPX3-1256 3U OpenVPX single board computer, has already been selected for a demanding military image processing program. The VPX3-491 joins the 6U OpenVPX VPX6-490, introduced earlier this year. These two GPGPU engines enable system designers to build 3U or 6U solutions, depending on the application requirements and the available SWaP envelope, with identical technology.

"The VPX3-491 is the first embedded GPGPU board to bring the highly parallel processing ability of NVIDIA's 240 core graphics processors to the 3U OpenVPX environment, providing system integrators with the highest performance small form factor GPGPU embedded building blocks available," said Lynn Bamford, vice president and general manager of Curtiss-Wright Controls Embedded Computing. "Combined with our 3U OpenVPX single board computers, FPGA engines and FMC I/O modules, we now offer the industry's most comprehensive and highest performance GPGPU solution for the most demanding SWaP-constrained HPEC applications."

The VPX3-491 takes full advantage of GPUs based on the NVIDIA Fermi architecture. Designed for high performance computing, the newest generation of NVIDIA processors feature larger internal shared memories, a completely new L2 cache, unified memory addressing and many other enhancements to improve CUDA-based applications performance and improve programmer productivity. The VPX3-491 supports its high performance GPU processor with a 2 Gbyte, 256-bit wide, 80 Gbyte/s GDDR5 memory subsystem designed to eliminate data bottlenecks and support large signal processing datasets into the onboard memory. The VPX3-491 supports a full 16-lane Gen2 PCIe interface to the backplane, supporting the maximum possible bandwidth between host and GPU. The VPX3-491also supports 8-lane and 4-lane PCIe interfaces.

The VPX3-491 is designed to work with Intel® processor-based SBCs, such as the Curtiss-Wright VPX3-1256 2nd Generation Intel Core™ single board computer.
