Constructing a scientific and effective bank risk forewarning model is an important measure to effectively guard against and defuse risks in commercial banks. this article constructs a bank risk forewarning model using BP neural network and principal component analysis method. Meanwhile, being aimed at that it takes a long time while processing the mass data to train the network, it also decomposes the algorithm for MapReduce, running in parallel to reduce the running time. the experiment result shows that the neural network model achieved higher accuracy of rate 88percents.

How to, eliminate redundant communications is a key issue in developing, parallelizing compilers for distributed' memory, machines. An important way, to) improve the, performance of the code generated by parallelizing compiler in distributed memory systems is to eliminate as much communications as possible. this paper investigates algorithms for generating communications code from previously published work and modifies them to eliminate redundant communications. Based on the mathematical model of symbolic coefficient linear inequalities the revisited formal specification of communications sets are presented and the corresponding improved algorithms are given. Experimental results indicate that the new algorithms can reduce communication messages and improve the performance of parallelized code significantly.
Within this keynote, selected research topics from the field of inter-organizatioanal elastic processes will be discussed, with a focus on the key challenges maintainability, reliability and correctness of such elasti...

Mobile cloud computing represents the most explicit attempt yet to move computing technology beyond the confines of tool usage towards a pervasive penetration. the increasing role and importance of mobile technology and cloud computing in our daily lives implies the need for new approach. the mobile users' motivation and cloud computing characteristics make them very appropriate for developing mobile cloud service. the aim of this paper is to complement previous research on adoption and use of mobile cloud computing by benefiting from theory of consumer research and media use, namely 'uses and gratification'. the focus is on cognitive, social and technological motivation dimensions that a mobile user experiences when possessing, interacting and using mobile devices with cloud computing.

Withthe rapid development of mobile Internet and electronic commerce, massive transactional operations under new data modules becomes the dominated workload of the database systems. In order to meet the functional and performance requirements of this kind of business, new distributed transactional databases system evolve fast. However, because of the distinct technical differences between the new distributed transactional database and traditional centralized transactional database, such as technical component architecture and principles of computing and storage, the evaluation framework and method for traditional database cannot directly apply to distributed transactional database. For example, the existing benchmarks can't evaluate high availability, scalability, and distributed consistency issues which are important characteristics after distribution. It is urgent for the industry to construct evaluation methods for distributed transactional databases so as to comprehensively measure the technical maturity and capability of these products. In this paper, we first summarize the definition and characteristics of distributed transactional database system. After evaluating the existing test benchmarks for distributed transactional database, we propose a new evaluation framework and test methods for distributed transactional database system. this paper provides a new guidance for testing and selecting distributed transactional database in the world.

the computing systems required to collect, analyse and store the physics data at LHC would need to be distributed and global in scope. CMS is actively involved in several grid-related projects to develop and deploy a fully distributedcomputing architecture. We present here recent developments of tools for automating job submission and for serving data to remote analysis stations. Plans for further test and deployment of a production grid are also described.

Virtualisation first and cloud computing later has led to a consolidation of workload in data centres that also comprises latency-sensitive application domains such as High Performance computing and telecommunication. these types of applications require strict latency guarantees to maintain their Quality of Service. In virtualised environments withtheir churn, this demands for adaptability and flexibility to satisfy. At the same time, the mere scale of the infrastructures favours commodity (Ethernet) over specialised (Infiniband) hardware. For that purpose, this paper introduces a novel traffic management algorithm that combines Rate-limited Strict Priority and Deficit round-robin for latency-aware and fair scheduling respectively. In addition, we present an implementation of this algorithm on the bmv2 P4 software switch by evaluating it against standard priority-based and best-effort scheduling.
