Amtrak, the passenger rail line serving more than
25 million passengers in 46 states nationally, has recently selected
components of the webMethods Fabric product suite to serve as the
foundation for the railway's enhanced IT infrastructure. Specifically,
Amtrak is leveraging webMethods to fully integrate its numerous IT
systems and transform those existing applications into functional Web
services within a service-oriented architecture (SOA). By unleashing
the full business value stored within its applications, Amtrak expects
to enjoy a significant boost in customer service, enhanced operational
flexibility and faster time-to-market.
"With webMethods, we have a trusted partner that will help transform
Amtrak's business systems to be fully services-enabled," said Derek
Rost, director of application architecture at Amtrak. "Leveraging the
benefits of a comprehensive SOA will allow Amtrak to tap into and reuse
our existing IT assets, and to extend the business value from those
investments across the entire organization."
Faced with the myriad of incompatible applications and technology
platforms common in large enterprises, Amtrak selected webMethods to
integrate its various IT systems and synchronize its silos of data.
Chief among Amtrak's concerns was the need to overcome the limitations
of the railway's mainframe-based, centralized ticket reservation
system, which made it difficult and costly to enact business process
changes in a timely manner. At the same time, Amtrak wanted to
eliminate the redundancies and maintenance overhead created by
point-to-point integration between its mainframe system and different
distribution channels, including the Web, self-service ticketing kiosks
and agents. Using webMethods' Enterprise Services Platform, Amtrak aims
to develop a comprehensive SOA that would house a common set of Web
services used to enhance and streamline the exchange of information
within and between its customer distribution channels and back-end
systems, beginning with its self-service kiosks.
As it moves to an SOA, Amtrak expects to enhance customer service
with easier and faster access to ticketing and reservation information
across the various distribution channels. At the same time, Amtrak
anticipates streamlining development and maintenance activities as less
time and effort will now be required to implement needed changes.
Added Steve Trus, director of e-commerce at Amtrak, "I'm confident
we've chosen the best partner to extend the value of our IT
infrastructure. webMethods considers our success to be instrumental to
its own success, and is committed to helping us become more agile and
adept at quickly meeting customer needs. Through the dedication of our
on-site technical account manager, we've already seen this commitment
in action and look forward to working with webMethods as we renew our
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.
