    DFSP: A New Algorithm for a Swift Computation of Formal Concept Set Stability

    Concept lattices are very useful for the task of knowledge discovery in databases. However, the overwhelming number of drawn formal concepts was always an actual hamper towards their effective use. In the aim of filtering out, such endless lists of formal concepts, the stability metric is the most worth of...

    From Start-up to SaaS Conglomerate: Life Cycles of Software Products

    A rationale behind the workshop was to provide a forum for researchers to present novel approaches and case studies, which they needed peer feedback on. The first international workshop from start-up to SaaS conglomerate: life cycles of software products, IW-LCSP 2013 was held in June 11th 2013 at Potsdam, Germany....

    NUMA Computing with Hardware and Software Co-Support on Configurable Emulated Shared Memory Architectures

    The Emulated Shared Memory (ESM) architectures are good candidates for future general purpose parallel computers due to their ability to provide an easy-to-use explicitly parallel synchronous model of computation to programmers as well as avoid most performance bottlenecks present in current multicore architectures. In order to achieve full performance the...

    Mixed-Criticality Run-Time Task Mapping for NoC-Based Many-Core Systems

    Contiguous processor allocation improves both the network and the application performance, by decreasing the congestion probability among communication of different applications. Consequently, the average, standard deviation and worst-case latency of the network are decreased significantly. This makes the contiguous allocation a good solution for time-critical applications with bounded deadlines. On...

    Adjustable Contiguity of Run-Time Task Allocation in Networked Many-Core Systems

    According to the International Technology Roadmap for Semiconductors, by 2020 Multi-Processor Systems-on-Chip (MPSoCs) will integrate hundreds of Processing Elements (PEs) connected by a Network-on-Chip (NoC) based communication infrastructure. NoCs provide a regular platform for connecting the system resources and make the communication architecture scalable and flexible compared to traditional bus...

    Transport Layer Aware Design of Network Interface in Many-Core Systems

    In this paper, the authors instigate the design of network interfaces which have knowledge about the transport layer and networking protocols of many-core systems. Workload dynamicity and multitasking are two main features of many-core systems, which are handled by relatively small kernels on each core. In the message-passing paradigm the...

    Embedding Fault-Tolerance with Dual-Level Agents in Many-Core Systems

    Due to the increasing influence of PVT variations and complex application scenarios, many-core systems rely on run-time optimization to achieve the expected performance, energy-efficiency and dependability. Dual-level fault-tolerance is presented on many-core systems, provided by the software-based system agent and hardware-based local agents. The system agent performs fault-triggered energy-aware remapping...

    Self-Adaptive NoC Power Management with Dual-Level Agents: Architecture and Implementation

    Architecture and Implementation of adaptive NoC to improve performance and power consumption is presented. On platforms hosting multiple applications, hardware variations and unpredictable workloads make static design-time assignments highly sub-optimal e.g. in terms of power and performance. As a solution to this problem, adaptive NoCs are designed, which dynamically adapt...

    Hybrid MAC Protocols Characteristics in Multi-Hops Wireless Sensor Networks

    In the current decade, wireless sensor networks are emerging as a peculiar multi-disciplinary research area. By this way, energy efficiency is one of the fundamental research themes in the design of Medium Access Control (MAC) protocols for wireless sensor networks. Thus, in order to optimize the energy consumption in these...

    Modified Uniform Triangular Array for Online Full Azimuthal Coverage Via JADE-MUSIC Algorithm Over MIMO-CDMA Channel

    This paper investigates a Modified Uniform Triangular Array (MUTA) to support online space-time MIMO-CDMA location based services with full azimuthal coverage via JADE-MUSIC algorithm. A new Space-Time Lifting Preprocessing (STLP) scheme is introduced as a decorrelating process of coherent signals through the dense/NLOS multipath MIMO channel before applying the JADE-MUSIC...
