    MOUNTAIN VIEW, Calif., Sept. 29 /PRNewswire/ -- PathScale, developer of
 innovative solutions to accelerate the performance and efficiency of Linux(R)
 clusters, this week announced that Voltaire is adding the PathScale
 InfiniPath(TM) HTX(TM) InfiniBand(TM) adapter as one of the InfiniBand
 adapters offered with its high-performance multi-service InfiniBand switches.
 This is the latest in a series of developments that demonstrate how PathScale
 InfiniPath has become the high-performance InfiniBand interconnect of choice
 for performance-minded cluster users.
     More details are available at
     One of the first Voltaire customers to receive the PathScale adapter is
 the Sandia National Laboratory's research facility in Livermore, CA.
 According to Dr. Matt Leininger, computational scientist at Sandia National
 Laboratories, "We see Voltaire's collaboration with PathScale as a very
 positive development that will make it easier for us to build extremely large
 InfiniBand-based clusters based on the OpenIB software stack.  The ability to
 couple the PathScale InfiniBand adapter to Hypertransport has some significant
 advantages in terms of latency and effective bandwidth for many of our complex
 applications such as structure mechanics, computational fluid dynamics and
 combustion codes.  PathScale's support for OpenIB is a critical requirement
 for us."
     PathScale InfiniPath, available as both an adapter card and as an ASIC, is
 the industry's highest performance Linux cluster interconnect for message
 passing (MPI) and TCP/IP applications.  InfiniPath delivers superior
 interconnect performance at commodity price levels by implementing a
 high-performance software stack and by connecting directly to the AMD
 Opteron(TM) processor via a standard HyperTransport HTX slot.  When integrated
 with Voltaire's InfiniBand-based switching solutions, InfiniPath enables
 applications to reliably scale to hundreds or thousands of nodes.
     "This agreement between PathScale and Voltaire marks InfiniBand
 technology's coming of age," observed Nathan Brookwood, principal analyst at
 the industry research firm Insight 64.  "Now the market will be served by
 multiple vendors offering customers a range of price/performance alternatives.
 PathScale's innovative marriage of InfiniBand and HyperTransport technology
 provides a low-latency interconnect that makes clusters of 64-bit x86 systems
 an even more cost-effective approach for high-performance computing
     Voltaire provides a complete family of grid backbone solutions including
 the Voltaire Grid Director(TM) ISR 9288, the industry's most scalable,
 multi-service switch for building high-performance clusters and grids ranging
 from tens to thousands of nodes.  To deliver complete cluster solutions to
 customers, Voltaire has established OEM agreements with leading server vendors
 IBM, HP, SGI, and strategic sales relationships with Sun, NEC and Hitachi.
     PathScale recently published new InfiniPath performance results including
 the Pallas Benchmark Suite and the HPC Challenge Benchmarks that validate
 PathScale InfiniPath as the industry's highest performance commodity cluster
 interconnect for Linux-based HPC applications.  These results can be viewed at
     The Voltaire HCA460HT InfiniBand adapter, based on PathScale InfiniPath is
 orderable immediately from Voltaire and its worldwide channel partner network.
