The SpiNNaker (Spiking Neural Network Architecture) project will soon deliver a machine incorporating a million ARM processor cores for real-time modelling of large-scale spiking neural networks. Although the scale of the machine is in the realms of high-performance computing, the technology used to build the machine comes very much from the mobile embedded world, using small integer cores and Network-on-Chip...
The cerebellum plays a critical role for sensorimotor control and learning. However dysmertria or delays in movements' onsets consequent to damages in cerebellum cannot be cured completely at the moment. To foster a potential cure based on neuroprosthetic technology, we present a frame-based Network-on-Chip (NoC) hardware architecture for implementing a bio-realistic cerebellum model with 100,000...
The demonstrator shows a self-management system for heterogeneous mobile wireless networks that uses context-specific and weighted Key Performance Indicator (KPI) target values defined by the operator to automatically and autonomously configure and control the operation of Self-Organising Network (SON) functions such that they contribute to achieving these KPI targets by appropriately optimising the...
Many-core architectures are playing an important role in the HPC systems. But they are giving high performance at the cost of a great electrical power consumption. On Tianhe-2 supercomputer, the Xeon Phi many-core processors contribute nearly 80% of the system power. Power models are important to guide the design of dynamic power management (DPM) algorithms by predicting the power consumption with...
This paper begins with a discussion of the role and value of network testbed which apply a universal experimental platform to test new theories, new technologies, and new vulnerabilities for cyber security research of networked systems. Several common aspects of NCR, Emulab, Testbed@TWISC, DETER lab, Planet Lab, SATURN, StarBED and GENI are introduced, mainly including: background, techniques, and...
Performance of software is increasingly restricted by the Memory Wall instead of CPU. Many studies focus on alleviating the DRAM latency by improving the row-buffer hit rate. But most of them treat the Kernel and User equally. Data used by Operating System and User applications spread in different rows of the same bank, leading to the contentions for the row-buffer when they access the bank successively...
Software architecture (SA) documentation provides a blueprint of a software-intensive system for the communication between stakeholders about the high-level design of the system. In open source software (OSS) development, a lack of SA documentation may hinder the use and further development of OSS, but how much "architecture" documentation is enough and appropriate is largely dependent on...
In recent years, The Internet of Things(IOT) is one of the hottest research topics. It was originally defined as connected all the things through the sensing devices to the Internet. In addition, Service-Oriented methodology has gradually drawn people's attention. Therefore, integrated The IOT with Service-Oriented methodology is very important. But now IOT service composition is mostly synchronous...
IT has changed business model and business process, and has become an essential ingredient for the competitive advantage. Under such circumstances, a conventional requirements engineering methodology is not sufficient. We propose an IT-driven business model design methodology in order to take advantage of innovative information technologies. The proposed methodology includes XBMC (eXtended BMC), an...
To prevent issues arising from legacy software platforms, adapting to changing customer needs by software evolution is a growing concern of software organizations. How-ever, current practices are pragmatic and subjective, which restricts benchmarking and reduces efficiency. In order to improve evolutionary practices, this paper proposes the Software Functionality Evolution Method (SFEM). The SFEM...
Recent decades have seen BCI applications as a novel and promising new channel of communication, control and entertainment for disabled and healthy people. However, BCI technology can be prone to errors due to the basic emotional state of the user: the performance of reactive and active BCIs decrease when user becomes stressed or bored, for example. Passive-BCI is a recent approach that fuses BCI...
Signal processing requires high performance digital signal processors(DSP) and hardware accelerators. Real and complex multiply-accumulate(MAC) units are the most critical computation units in the DSPs and accelerators, which greatly impact the performance, power and chip area of the signal processing system. A fixed-point Single-Instruction-Multiple-Data(SIMD)/vector MAC architecture is presented...
A Smart Grid approach to electric distribution system management needs to front uncertainties in generation and demand thus making forecasting an up-to-date area of research in electric energy systems. This works aims to propose a day-ahead load forecasting procedure for a medium voltage customer. The load forecasting is performed through the implementation of an artificial neural network (ANN). The...
New challenges will arise with the emergence or Exascale systems. Such challenges are linked power consumption, Input/Ouput and memory performances, scalability of highly concurrent and hierarchical systems and the major one could be reliability. Codesign of software tools for Exascale machines and disruptive technologies will help to face the current challenges. In this talk we will focus on benchmarking...
Modular addition and multiplication plays an important role in data encryption standard. In this paper a new VLS I circuit architectures for addition and multiplication of modulo 2n+1 are presented, which allows the implementation of highly efficient combinational circuits for modular arithmetic. The architecture for adder and multipliers are based on Diminished-1 representation. To realize the architecture...
Considering the dispersion of resources and the uneven distribution of architecture of digital library, this paper proposes a digital library based on inter cloud containing four layers, namely physical layer, internet layer, metadata layer and application layer, analyzes the function of each layer, and describes its resource organization, storage, retrieval and access processes. The simulation results...
Network connectivity offers the potential for a group of musicians to play together over the network. This paper describes a trans-Atlantic networked musical livecoding performance between Andrew Sorensen in Germany (at the Schloss Daghstuhl conference on Collaboration and Learning through Live Coding) and Ben Swift in San Jose (at YL/HCC) in September 2013. In this paper we describe the infrastructure...
In a software development life cycle, system requirement management is an important but neglected step. A good requirement management can not only help developers to meet the requirements of the system, but also play an essential role for the communication among the stakeholders. Usually, natural language is used to describe and record the user requirements, yet it tends toward the situation of ambiguity,...
