Curtiss-Wright Controls Announces Demonstration of OFED Stack on the Industry's Highest Performing OpenVPX(TM) HPEC System

Open Source APIs Enable Abstraction of Heterogeneous Software to Bring Commercial HPC Architectures to Rugged, Deployed Defense and Aerospace Subsystems (March 13, 2012)

ASHBURN, VA -- (Marketwire) -- 03/13/12 -- Curtiss-Wright Controls Defense Solutions (CWCDS), a business unit of Curtiss-Wright Controls, has announced that its HPEC (High Performance Embedded Computing) Center of Excellence has conducted the first successful demonstration of OpenFabrics Enterprise Distribution (OFED™) software running on its CHAMP-AV8 series dual 2nd generation Intel® Core™ i7 DSP module enabled with Gen2 Serial RapidIO (SRIO). Curtiss-Wright's HPEC system can support over 3.7 Intel® AVX TFLOPS and 224 GB/sec of fabric connectivity in a standard 16-slot OpenVPX™ chassis. Curtiss-Wright's HPEC system, which supports eight Intel® cores and bandwidth rated at 8 GB/sec to the data plane, is the industry's highest performing HPEC system on a FLOPS/Watt basis. The demonstration was performed using COTS silicon and open source software, which further emphasizes the Curtiss-Wright HPEC system's open architecture compared to alternative OpenVPX systems that require proprietary RapidIO IP and software stacks.

The demonstration represents a major achievement in the development of rugged COTS-based embedded HPEC systems for use in the most demanding Radar, SIGINT/EW, Imaging and other ISR applications. The OFED cross-platform, open-source API software was implemented on Curtiss-Wright's rugged Intel® processor-based CHAMP-AV8 multiprocessor DSP board and VPX6-6902 Switch Card. The demonstration included OpenMPI, an open source implementation of the message passing interface, RapidIO RIONet, an Open-source component that transports Ethernet frames seamlessly over RapidIO Messages, and DAPL/UDAPL InfiniBand® fabric APIs. OFED support enables system integrators to run their application software coded for Ethernet and InfiniBand systems natively on CWCDS rugged, deployable hardware that transparently runs the Gen2 Serial RapidIO fabric.

"We are very proud to offer military COTS solutions providers the highest performing OFED middleware implementation running on open standard rugged OpenVPX HPEC hardware," said Lynn Bamford, senior vice president and general manager of Curtiss-Wright Controls Defense Solutions. "The migration of commercial HPC system architectures and software promise to revolutionize the levels of processing performance that can be deployed to the warfighter, delivering previously unattainable amounts of actionable data and situational awareness derived from ever increasing amounts of signal and sensor inputs."

OFED is an open source software component that abstracts fabrics and operating system RDMA from higher level software. OFED is governed by the OpenFabrics Alliance, with many contributors across the industry. OFED supports multiple fabrics such as Serial RapidIO, Ethernet, InfiniBand and multiple operating systems including Linux and Windows.

OFED Demonstration Features:

  • Linux BSP: Fedora Linux version 15, 64-bit, SMP
  • RIONET: Linux software component that transports Ethernet frames over a Serial RapidIO fabric.
  • OFED - OpenFabrics Enterprise Distribution (OFED™) fabric API
  • OpenMPI - Open Source implementation of a Message Passing Interface (MPI)
  • UDAPL/DAPL - Legacy InfiniBand fabric API's supported by Mellanox
