Industry's First NVIDIA Fermi GPU OpenVPX Engine

480 cores on a board for military digital signal rpocessing

By Nick Flaherty

Marking a key move of massively parallel graphics technology from the PC desktop to the embedded world, Curtiss-Wright Controls Embedded Computing (CWCEC) has developed the industry's first openVPX board based on NVIDIA's Fermi graphics engine.
The VPX6-490 GPU Application Accelerator uses two NVIDIA GPUs based on the Fermi architecture, each with 240 CUDA cores. Integrated into a High Performance Embedded Computing (HPEC) subsystem, VPX6-490 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
This combination is aimed at demanding military digital signal processing (DSP) applications such as C4ISR, EO/IR and SatCom.
"The VPX6-490 uniquely brings NVIDIA's new 240 core graphics processors to the rugged deployed environment, providing system integrators with the highest performance GPGPU embedded building blocks available," said Lynn Bamford, vice president and general manager of Curtiss-Wright Controls Embedded Computing. "Combined with our 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 HPEC applications."
"Rugged open-architecture processing modules, like Curtiss-Wright's VPX-490, will enable military system designers to leverage the massively parallel performance of our newest GPUs," said Taner Ozcelik, general manager, embedded and automotive business, NVIDIA.
The VPX6-490 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 VPX6-490 supports its dual high performance GPU processors 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. Each GPU device supports a full 16-lane Gen2 PCIe interface to the backplane, supporting the maximum possible bandwidth between host and GPU. The VPX6-490 also supports 8-lane and 4-lane PCIe interfaces.
