Special Issue on Parallel and Distributed Data Mining
by Massimo Cafaro 27 Nov '17

27 Nov '17

Special Issue on Parallel and Distributed Data Mining Information Sciences, Elsevier Submission deadline: February 1st, 2018 The sheer volume of new data, which is being generated at an increasingly fast pace, has already produced an anticipated data deluge that is difficult to challenge. We are in the presence of an overwhelming vast quantity of data, owing to how easy is to produce or derive digital data. Even the storage of this massive amount of data is becoming a highly demanding task, outpacing the current development of hardware and software infrastructure. Nonetheless, this effort must be undertaken now for the preservation, organization and long-term maintenance of these precious data. However, the collected data is useless without our ability fully understand and make use of it. Therefore, we need new algorithms to address this challenge. Data mining techniques and algorithms to process huge amount of data in order to extract useful and interesting information have become popular in many different contexts. Algorithms are required to make sense of data automatically and in efficient ways. Nonetheless, even though sequential computer systems performance is improving, they are not suitable to keep up with the increase in the demand for data mining applications and the data size. Moreover, the main memory of sequential systems may not be enough to hold all the data related to current applications. This Special Issue takes into account the increasing interest in the design and implementation of parallel and distributed data mining algorithms. Parallel algorithms can easily address both the running time and memory requirement issues, by exploiting the vast aggregate main memory and processing power of processors and accelerators available on parallel computers. Anyway, parallelizing existing algorithms in order to achieve good performance and scalability with regard to massive datasets is not trivial. Indeed, it is of paramount importance a good data organization and decomposition strategy in order to balance the workload while minimizing data dependences. Another concern is related to minimizing synchronization and communication overhead. Finally, I/O costs should be minimized as well. Creating breakthrough parallel algorithms for high-performance data mining applications requires addressing several key computing problems which may lead to novel solutions and new insights in interdisciplinary applications. Moreover, increasingly the data is spread among different geographically distributed sites. Centralized processing of this data is very inefficient and expensive. In some cases, it may even be impractical and subject to security risks. Therefore, processing the data minimizing the amount of data being exchanged whilst guaranteeing at the same time correctness and efficiency is an extremely important challenge. Distributed data mining performs data analysis and mining in a fundamentally distributed manner paying careful attention to resource constraints, in particular bandwidth limitation, privacy concerns and computing power. The focus of this Special Issue is on all forms of advances in high-performance and distributed data mining algorithms and applications. The topics relevant to the Special Issue include (but are not limited to) the following. TOPICS OF INTEREST Scalable parallel data mining algorithms using message-passing, shared-memory or hybrid programming paradigms Exploiting modern parallel architectures including FPGA, GPU and many-core accelerators for parallel data mining applications Middleware for high-performance data mining on grid and cloud environments Benchmarking and performance studies of high-performance data mining applications Novel programming paradigms to support high-performance computing for data mining Performance models for high-performance data mining applications and middleware Programming models, tools, and environments for high-performance computing in data mining Map-reduce based parallel data mining algorithms Caching, streaming, pipelining, and other optimization techniques for data management in high-performance computing for data mining Novel distributed data mining algorithms SUBMISSION GUIDELINES All manuscripts and any supplementary material should be submitted electronically through Elsevier Editorial System (EES) at http://ees.elsevier.com/ins (http://ees.elsevier.com/ins).

CFP: Special Issue on 'Software Defined Networking and Network Function Virtualization' in Scalable Computing and Communications (Springer)
by Javid Taheri 19 Nov '17

19 Nov '17

--------------------------------------------------------------------------------- Please accept our apologies if you receive multiple copies of this CFP --------------------------------------------------------------------------------- CALL FOR PAPERS Scalable Computing and Communications ~Special Issue Call for Papers~ Software Defined Networking and Network Function Virtualization IMPORTANT DATES: - Submission Deadline: 15 Dec 2017 - Notification of Acceptance: 31 March 2018 - Final Version: 31 May 2018 INTRODUCTION AND MOTIVATION With maturity of virtualization techniques, more and more services are to be run inside virtualized Data Centers vDCs) to further reduce Operational (OPEX) and Capital Expenditures (CAPEX). Aligned with the general trend of migrating traditional IT architectures to clouds (public or private), next generation of telecommunication networks such as 5G are also envisaged to be run on virtualized environments where network functions are deployed on virtual machines and/or containers instead of current proprietary equipment. Several proof-of-concept and initial industrial deployments proved that Software Defined Networking (SDN) and Network Function Virtualization (NFV) are two promising technologies to enable such technological shift. Nevertheless, how to optimize and guarantee the performance of such virtualized systems is still challenging, because they require accurate modelling and efficient optimization to satisfy ever increasing demand of future networks. To address several major issues raised by migrating network applications to virtualized infrastructures, this special issue aims to highlight challenges, state-of-the-art, and solutions to a set of currently unresolved key questions including, but not limited to: performance, modelling, optimizations, reliability, security, and techno-economic aspects of virtualized networks. By addressing these concerns, technology might be one step closer to understanding, and consequently, closing the gap between the performance of the next generation SDN/NFV-based networks and their current counterparts in proprietary boxes. In this special issue, we welcome contributions that can shed light onto any of the following questions: 1. How virtualized networks should be designed to guarantee the performance required by network operations? 2. How virtualized services can be benchmarked and/or compared? 3. How virtualized services should be designed and/or operated to take advantage of cloud infrastructures and further provide flexibilities (such as load migration) that current proprietary equipment cannot provide? 4. How network functions should be placed and/or network capacities should be sliced to optimize network critical metrics such as throughput, delay, jitter, etc.? 5. How virtualized services should/can be efficiently orchestrated, monitored, and managed? PAPER SUBMISSION: - Authors are encouraged to submit high-quality, original work that has neither appeared in, nor is under consideration by, other journals. - All papers will be reviewed following standard reviewing procedures for the Journal. - Papers must be prepared in accordance with the Journal guidelines: www.springer.com/41122 - Submit manuscripts to: http://SCAC.edmgr.com. Topics to be covered in this Special Issue are including, but not limited to: 1. Model, benchmark, and/or optimize operation of SDN/NFV-based networks and services. 2. Resource and/or content allocation for SDN/NFV-based networks and services. 3. Reliability and resiliency of SDN/NFV-based networks and services. 4. Dynamic/flexible construction and deployment of Service Function Chains using SDN/NFV technologies. 5. Fault detection and/or correction for SDN/NFV-based networks and services. 6. Architectures, applications, and use cases of SDN/NFV to provide networking services. 7. Monitoring techniques for SDN/NFV-based networks and services. 8. Deployment, management, and orchestration of SDN/NFV-based networks and services. 9. Business/economic aspects of SDN/NFV-based networks and services. 10. Security concerns of SDN/NFV-based networks and services. 11. Mobile and/or Wireless Networks enabled by SDN/NFV-based networks and services.
