APEnet+: high bandwidth 3D torus direct network for petaflops scale commodity clusters

We describe herein the APElink+ board, a PCIe interconnect adapter featuring the latest advances in wire speed and interface technology plus hardware support for a RDMA programming model and experimental acceleration of GPU networking; this design allows us to build a low latency, high bandwidth PC cluster, the APEnet+ network, the new generation of our cost-effective, tens-of-thousands-scalable cluster network architecture. Some test results and characterization of data transmission of a complete testbench, based on a commercial development card mounting an Altera FPGA, are provided.Comment: 6 pages, 7 figures, proceeding of CHEP 2010, Taiwan, October 18-2

Moving HomePlug to Industrial Applications with Power-Line Communication Network

Home networking is becoming an attractive application not only for the Internet access but also for home automation. Being a high-speed and dominant standard presently, HomePlug has an important role in home LAN connecting to the Internet. For industrial applications, the Power Line Communication also has significant advances. However, the PHY/MAC technology provided by HomePlug still cannot be employed with some critical features such as real time performance, implications in the event of link and node loss. In this paper, the characteristics of HomePlug PHY/MAC, the property of power line channel, as well as the noise features of power line are analyzed. Based on HomePlug, a model of high level real-time protocol applied to industrial environment is proposed. The protocol simultaneously belongs to layer two and three, and can support real-time implementation with no loss and small delay according to the requirement in PLC networks, for targeting to develop a real time network with high speed power line media and advanced modulation.Singapore-MIT Alliance (SMA

Optical network technologies for future digital cinema

Digital technology has transformed the information flow and support infrastructure for numerous application domains, such as cellular communications. Cinematography, traditionally, a film based medium, has embraced digital technology leading to innovative transformations in its work flow. Digital cinema supports transmission of high resolution content enabled by the latest advancements in optical communications and video compression. In this paper we provide a survey of the optical network technologies for supporting this bandwidth intensive traffic class. We also highlight the significance and benefits of the state of the art in optical technologies that support the digital cinema work flow

Railways in Renaissance — Review of Achievements and Reflection on Prospects

The authors introduce railway renaissance by considering the rail mode\u27s inherent strengths, energy frugality, and developmental role. They address the research question: Does a new post-renaissance normal now prevail? The research progresses a multivariate design that they developed to a case study approach as proliferation of private railway operators as a consequence of renaissance has constrained access to formerly public information. The study examined four countries, Brazil, Russia, India, and China, and one region, the Gulf Cooperation Council States, whose railways have advanced substantially in recent years through implementation of high speed, heavy haul, heavy intermodal, and urban rail. It also examined the migration of countries from the previously identified Fortuitous and Insecure railways clusters to the Enlightened, Progressive, and Assertive clusters. It found advances in institutional learning with respect to design of interventions to achieve renaissance, ownership and funding, market structure, as well as networking and expanding strategic horizons. It concluded that countries that have embraced the railway renaissance have been able to reposition their railways to play a substantial role in their economies and societies, and that a new normal has emerged, with the rail mode now a formidable contender in high-speed, high-volume, heavy-traffic corridors
