ADVA Optical Networking has announced that its Fiber Service Platform (FSP) 2000 DWDM (Dense Wavelength Division Multiplexing) transport system has been successfully deployed in a field demonstrator for the transmission of 10 Gbit/s Fibre Channel (10G-FC) signals between the German Universities of Stuttgart and Hohenheim.
The field demonstrator involved 10G-FC DWDM transmission using the FSP 2000 on a link between the High Performance Computing Center Stuttgart (HLRS), University of Stuttgart, and the University of Hohenheim in southwest Germany. Throughout the course of the testing, speeds of more than 10.1 Gbit/s were achieved. The multi-layer system was connected in part using 4G-FC local interfaces, which deliver 100 percent more bandwidth than 2 Gbit/s links, but at only 10 to 20 percent higher cost. Both 4 Gbit/s or 10 Gbit/s systems enable higher bandwidth levels with the potential to lower operating expense, and are suited for enterprises launching newer, bandwidth-intensive applications utilizing graphics and video.
Delivering the bandwidth and support of protocols like 10G-FC, ADVA Optical Networking's WDM systems can support up to 80 channels ready for 10G-FC or other high-speed protocols. With a WDM solution in place, customers can connect any storage area network (SAN) fabric or high performance computer over high-bandwidth metro and regional transparent optical networks. This enables applications such as Grid computing, server and storage consolidation, disaster recovery and business continuity.
"We are connecting high-performance computing clusters over longer distances, enabling collaboration with other universities and us to build a flexible, scalable internal network for storage and other critical applications," explained Peter Haas, director of data and network management at HLRS. "We are now sharing scientific research and data around the world and have established Grid computing architectures that allow us to share processing power across disparate sites for high-capacity scientific applications in a virtual setting. This network capability would not be possible without WDM as the foundation."
ADVA Optical Networking has supported the Universities of Stuttgart and Hohenheim since 2001 with an FSP 2000 link operating at 2.5Gbit/s. In 2004, ADVA Optical Networking demonstrated upgradeability of this link to 10 GbE. Now, with this latest 10G-FC demonstrator, ADVA Optical Networking again showed its commitment to providing leading-edge functionality and interoperability for scientific, educational and enterprise customers.
"With a WDM-enabled optical network now in place, these universities have a powerful tool for management of current resources and can plan for growth into the future," stated Dieter Will, VP business management enterprise for ADVA Optical Networking. "The drivers for high-performance WDM-based optical networks will not slow. The ability to simultaneously drive down costs and drastically improve performance with innovative optical transport technologies is exciting for organizations with growing storage and communications needs."
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.

Ruan Pethiyagoda, Cameron Boehmer, John S. Dvorak, and Tim Sze, trained at San Francisco’s Hack Reactor, an institute designed for intense fast paced learning of programming, put together a program based on the N-Queens algorithm designed by the University of Cambridge’s Martin Richards, and modified it to run in parallel across multiple machines.
