HANOVER, Md., Feb. 22 – Ciena Corporation, the network specialist, today announced that its 100G solution, architected with WaveLogic Coherent Optical Processors, has been deployed by Telefonica Vivo. This is the first active 100G network in Brazil, which connects native 100GbE channels to the DWDM system to provide unprecedented speeds for outbound international traffic. The network includes 100G routes that connect the cities of São Paulo, Rio de Janeiro and Praia Grande, Brazil. Ciena’s industry-leading 100G coherent solution will add significant bandwidth, scalability and reliability to Telefonica Vivo’s network infrastructure.
Telefonica is the largest mobile operator in Brazil with 76 million customers and is also the top performing wireless company based on the national telecommunications sector watchdog Anatel’s quality indicators. The company has 3.7 million fixed broadband customers and 610,700 pay TV access points in Brazil.
With this regional and long-haul domestic network upgrade, Telefonica Vivo becomes the first network operator in Brazil to deploy 100G, allowing the operator to extract more capacity out of existing fiber and support the delivery of high-bandwidth services and applications.
The upgraded network, spanning hundreds of kilometers, will provide 100G transport between the cities of São Paulo, Rio de Janeiro and Praia Grande, Brazil over multiple routes.
Telefonica Vivo and Ciena have a long-term relationship and have been working together for more than ten years.
“Demand for capacity will continue to grow because of the increasing number of connections to public and private networks, as well as the business and consumer demand for applications such as video and remote storage," said Fabio Medina, vice president and general manager of Ciena in Central and Latin America. "Addressing this challenge requires a network that is future-proof and that combines intelligence, scalability and high capacity - and that is where Ciena’s intelligent infrastructure comes into play. We are thrilled to support Telefonica Vivo in building the country’s first 100G network, which will allow Brazilians to enjoy advanced, high-speed applications and services.”
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.
