The Liberty Alliance Project, a
global consortium for open federated identity and Web services
standards, announced that products from IBM, NEC, NTT and RSA
Security passed interoperability testing at Liberty's recent
conformance event. These companies successfully demonstrated that their
products meet interoperability standards for Liberty Federation and
join nearly seventy other identity products and solutions from multiple
vendors that have now passed Liberty interoperability testing.
Liberty Alliance holds regular conformance events at varying
locations around the world to test products for interoperability of
Liberty identity specifications. After participating in a five-day
testing event held in Tokyo earlier this month, IBM, NEC, NTT and RSA
Security have demonstrated interoperability of products and solutions
that incorporate Liberty Federation (Liberty ID-FF 1.2 and/or SAML 2.0)
"Liberty's Interoperable Program is about creating a global
ecosystem of identity solutions that have been proven to work together
in an open federated network environment," said Roger Sullivan, chair
of the Liberty Alliance conformance program and vice president of
business development for Oracle's Identity Management. "Since Liberty
launched the program in 2003, identity products that have passed
interoperability testing have been deployed extensively in a variety of
industries and vertical market segments worldwide."
Liberty Alliance is the only global identity organization with a
history of ensuring identity products from multiple vendors truly
interoperate. Implementations must interoperate with at least two other
vendor implementations through a series of tests designed to
exhaustively exercise specification features in a real-world deployment
setting. Symlabs and Trustgenix supported the testing by providing
their previously validated Liberty Interoperable products and
Interoperability of products is a key factor in deploying and
managing successful identity systems. Organizations specifying products
that have met Liberty's requirements for interoperability can count on
solutions that will deploy quickly and immediately interoperate with
other Liberty-enabled identity solutions. This allows organizations to
deploy open federated identity systems faster, more cost-effectively
and on the widest possible scale.
The ever-growing complexity of scientific and engineering problems continues to pose new computational challenges. Thus, we present a novel federation model that enables end-users with the ability to aggregate heterogeneous resource scale problems. The feasibility of this federation model has been proven, in the context of the UberCloud HPC Experiment, by gathering the most comprehensive information to date on the effects of pillars on microfluid channel flow.
Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).
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 study of climate change is one of those scientific problems where it is almost essential to model the entire Earth to attain accurate results and make worthwhile predictions. In an attempt to make climate science more accessible to smaller research facilities, NASA introduced what they call ‘Climate in a Box,’ a system they note acts as a desktop supercomputer.

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.
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. Use this quick article to jump-start your own thinking on heterogeneous computing.
