MCI Inc. teamed with Xtera Communications, Mintera Corp., and Juniper Networks
to successfully transmit 40 Gigabits per second (Gbps) over 3,040 km of
field fiber in MCI's Dallas metro area network. This milestone
demonstrates that next generation technology is now available to
support high-bandwidth IP traffic demands over Ultra Long Haul (ULH)
distances on existing fiber infrastructure while maintaining reliable
"MCI continues to lead the industry in technology innovation and the
delivery of next generation IP services," said Jack Wimmer, MCI vice
president of Network Architecture and Advanced Technology. "As we
execute on our IP convergence strategy, and as customer applications
drive bandwidth onto our network, 40 Gbps transmission becomes an
increasingly important technology to enable efficient scaling of our
The technology field trial, which was conducted in October and
November, carried 74 channels of 10 Gbps traffic and 2 channels of 40
Gbps traffic over 38 individual 80 km spans of standard single mode
fiber around the Dallas metro area using the Xtera all-Raman DWDM
system, Mintera advanced modulation format long reach OC768
transponders, and Juniper Networks T640 IP routers with OC768 short
Using patented all-Raman technologies, Xtera's Nu-Wave Multi-Reach
DWDM platform supports 40 Gbps transmission with unprecedented reach,
extremely high bandwidth, and extensive Optical Add-Drop Multiplexer
(OADM) flexibility to deliver high-quality video, data and advanced
This all-Raman amplifier allows the optical signal to be carried a
greater distance with three times the capacity of most traditional
Erbium Doped Fiber Amplifiers (EDFA). As a result, an all-Raman
approach can translate into lower network costs, increased reliability,
reduced infrastructure builds, simplified channel engineering and
streamlined capacity planning.
Mintera's MI 40000 optical transport equipment enables carriers to
deploy 40 Gbps wavelengths without traffic interruption on
infrastructures designed for, and simultaneously, carrying lower
bit-rate signals. A variety of modulation formats, including DPSK, are
employed to permit this boost in bandwidth efficiency to be implemented
without adding regeneration sites, thus significantly lowering overall
Juniper Networks OC768c router interface enables carriers to
increase the efficiency and capacity of IP networks to better support
bandwidth-intensive applications and services. The Juniper Networks
T-series routing platform offers a combination of advanced routing
features, IP/MPLS capabilities, reliability and scale to support
high-capacity core applications. In combination with the JUNOS software
feature set, the T-series provides the flexibility and scale to help
meet growing bandwidth capacity requirements.
MCI originally demonstrated high-capacity Internet technology in May
2004 when the company successfully transmitted the world's first 40
Gbps IP traffic using MCI optical network fiber between San Francisco
and San Jose, Calif. That was followed weeks later with MCI
extending the reach of 40 Gbps wavelengths to 1,200 km, using the
company's ULH backbone network between Sacramento, Calif., and Salt
Researchers from the Suddhananda Engineering and Research Centre in Bhubaneswar, India developed a job scheduling system, which they call Service Level Agreement (SLA) scheduling, that is meant to achieve acceptable methods of resource provisioning similar to that of potential in-house systems. They combined that with an on-demand resource provisioner to ensure utilization optimization of virtual machines.
Experimental scientific HPC applications are continually being moved to the cloud, as covered here in several capacities over the last couple of weeks. Included in that rundown, Co-founder and CEO of CloudSigma Robert Jenkins penned an article for HPC in the Cloud where he discussed the emergence of cloud technologies to supplement research capabilities of big scientific initiatives like CERN and ESA (the European Space Agency)...
When considering moving excess or experimental HPC applications to a cloud environment, there will always be obstacles. Were that not the case, the cost effectiveness of cloud-based HPC would rule the high performance landscape. Jonathan Stewart Ward and Adam Barker of the University of St. Andrews produced an intriguing report on the state of cloud computing, paying a significant amount of attention to the problems facing cloud computing.

With that in mind, Datapipe hopes to establish themselves as a green-savvy HPC cloud provider with their recently announced Stratosphere platform. Datapipe markets Stratosphere as a green HPC cloud service and in doing so partnering with Verne Global and their Icelandic datacenter, which is known for its propensity in green computing.

The San Diego Supercomputer Center launched a public cloud system for universities in the area designed specifically to run on commodity hardware with high performance solid-state drives. The center, which currently holds 5.5 PB of raw storage, is open to educational and research users in the University of California.
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
04/02/2012 | AMD | Developers today are just beginning to explore the potential of heterogeneous computing, but the potential for this new paradigm is huge. This brief article reviews how the technology might impact a range of application development areas, including client experiences and cloud-based data management. As platforms like OpenCL continue to evolve, the benefits of heterogeneous computing will become even more accessible.
