With support from the Office of the Secretary of Defense, experts from the Naval Postgraduate School (NPS), Microsoft Corp., Cisco Systems and other private sector research partners gathered in Bay St. Louis, Miss., to deploy a "Hastily Formed Network" (HFN), a NPS research initiative that serves as an operational field laboratory for the W2COG. The mission was to rapidly build a communications infrastructure out of the rubble of Hurricane Katrina in the Bay St. Louis and Waveland areas of Mississippi.
The team of 15 students and one faculty member from NPS brought in satellite broadband Internet access, 802.11 (WiFI) and 802.16 (WiMAX) wireless communications, Voice Over Internet Protocol (VoIP), Skype Internet telephony, and the Groove collaborative workspace to enable communications among the local population, state and federal emergency services, and government and non-government organizations (NGOs) that were providing disaster relief. Working out of mobile vans primarily with commercial-off-the-shelf (COTS) components and equipment, the team has created communication zones that support makeshift shelters at Wal-Mart, Kmart and Fred's parking lots, schools and hospitals. Additionally, the team has helped establish and supplement communications among the National Guard, local government offices and fire and police departments in an area recognized as Katrina's "ground zero."
"We learned during last year's tsunami relief efforts that reliable communications is vital to saving lives during a disaster," explained Chris Gunderson, executive director of W2COG. "We've been able to take the lessons learned then and put them to good use to support the relief efforts in Mississippi."
"In establishing simple Internet access and basic telephone services in an area that lost its entire infrastructure, the team has learned a number of valuable lessons about these technologies and their capabilities," said Brian Steckler, an NPS professor and the W2COG HFN project team leader. "From purely technical issues, such as the hasty integration of disparate applications, to basic logistical concerns such as transportation of equipment, the information we are collecting here will no doubt result in even faster responses in the future - both in the United States and overseas."
The NPS/W2COG and partner
vendor collection of HFN field lab equipment will remain on site until
a Federal Emergency Management Agency contracted team of private sector
companies replaces the infrastructure, sometime in the next 30-60 days.
Complete restoration of original telecommunications infrastructure is
expected to take six to 12 months.

Frank Ding, engineering analysis & technical computing manager at Simpson Strong-Tie, discussed the advantages of utilizing the cloud for occasional scientific computing, identified the obstacles to doing so, and proposed workarounds to some of those obstacles.
The private industry least likely to adopt public cloud services for data storage are financial institutions. Holding the most sensitive and heavily-regulated of data types, personal financial information, banks and similar institutions are mostly moving towards private cloud services – and doing so at great cost.
In this week's hand-picked assortment, researchers explore the path to more energy-efficient cloud datacenters, investigate new frameworks and runtime environments that are compatible with Windows Azure, and design a uniﬁed programming model for diverse data-intensive cloud computing paradigms.

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.
