Gnodal Fabric "Frees the Network" for 10-Gigabit Ethernet iWARP Performance Test
SALT LAKE CITY, UT, Nov 14, 2012 (MARKETWIRE via COMTEX) --
Today at SC12, Gnodal Limited, the high-performance data center
networking company, announced that its Gnodal(R) GS7200 Switch
supported Intel's performance testing of ESI Group's PAM-CRASH
physics-based simulation software. The test demonstrates that iWARP
(RDMA over Ethernet) is a viable alternative to proprietary fabrics,
providing the opportunity for High Performance Computing (HPC)
operators to benefit from its cost-efficiency and flexibility.
The Gnodal GS7200 Switch was used in a simulation of a car-to-car
crash to compare performance of iWARP technology versus InfiniBand.
The tests conducted by researchers at Intel Corporation demonstrated
improved results for 10-Gigabit Ethernet (GbE) networking with iWARP
technology, confirming that the advantages of iWARP over proprietary
technologies such as Infiniband are available without significant
performance penalty. This heralds the opportunity to support
scientific and engineering applications within a converged network
environment, providing the necessary low-latency requirements through
a combination of RDMA and the industry leading low-latency of the
Gnodal GS-Series.
"Gnodal GS-Series Switches, as demonstrated in the benchmark, are
able to support the requirements of iWARP for typical ISV
applications," said Dr. John Taylor, Gnodal Vice President of
Technical Marketing. "The Gnodal Ethernet Fabric not only allows all
paths to be used within the network, it also dictates 'fairness' in
their use, ensuring that applications are not starved of resources."
Gnodal engaged with Intel's LAN Access Division to test a number of
ISV codes within a converged network setting, using NetEffect
Ethernet Server Cluster Adapters from Intel that support RDMA, and
the Gnodal GS-Series switches that use highly efficient
implementations of loss-less Ethernet standards. This transport
offered precise support of the OpenFabrics Enterprise Distribution
(OFED(TM)) environment, obviating particular kernel operations,
coupled with unique support for TCP/IP flows. This has particular
advantages in providing the necessary inter-server Message Passing
Interface (MPI) communications, as well as standard networking
operations.
The Gnodal GS7200 Switch enabled Intel's benchmarking around iWARP --
the standard RDMA protocol for Ethernet -- and has proven that the
typical use-case for Infiniband supporting moderate scale-out HPC is
now possible with High-Speed Ethernet. This implementation enables
users the performance value and benefits of the Ethernet standard in
terms of integration, management, and access to a richer set of
third-party peripherals -- all of which decrease the total cost of
ownership of HPC resources.
"The PAM-CRASH test proves that the Gnodal ASIC Ethernet architecture
with High-Speed Ethernet, built around low-overhead RDMA Ethernet
protocols and Ethernet Fabrics that provide low-latency at scale with
congestion avoidance built-in, can sustain a converged network
strategy in traditional HPC environment," added Dr. Taylor of Gnodal.

About Gnodal
The Gnodal(R) ASIC Ethernet switch architecture features a
congestion-aware performance and workload engine that allows for
ultra-low latency transmission while utilizing a dynamic, fully
adaptive load-balancing mechanism to arbitrate equitably a
pre-emptive pathway for large data-sets, high-computational
applications and massive storage demands prevalent in HPC and Big
Data environments. The 72-port, 40-GbE, "fabric-in-a-box" GS0072
solution extends Gnodal leadership in port density ToR solutions and
won the best-in-class award for networking at Interop 2012
(www.bestofinterop.com/winners).
Gnodal high-performance network fabrics deliver industry leading
speed to help reduce latencies. Gnodal highest port density 1U and 2U
ToR switches are ideally suited for deployment within co-location
environments and enterprise data centers. On ingress into GS-Series
switching, the initial latency is sub-150 nanoseconds (store/forward)
with each subsequent Gnodal switch added to the fabric incurring only
66 nanoseconds of additional latency (cut-through).
