Development of banking business leads to system maintenance amount of work increase greatly. In order to discover and resolve the abnormal circumstance in time, and avoid producing greater adverse effects, it is important to apply one method of automatic monitoring, and get alarms and reports directly. This paper introduces an application on AIX platform which is programmed by SHELL code. It can monitor important indexes of banking business front system, give alarms and reports by IPMSG. It helps to discover and resolve banking business system problems in time, guard against risk, and raise working efficiency.

In this paper, a coupling strategy of the Parareal algorithm with the Waveform Relaxation method is presented for the parallel solution of differential algebraic equations. The classical Waveform Relaxation (in space) method and the Parareal (in time) method are first recalled, followed by the introduction of a coupled Parareal-Waveform Relaxation method recently introduced for the solution of partial differential equations. Here, this coupled method is extended to the solution of differential algebraic equations. Numerical experiments, performed on parallel multicores architectures, illustrate the impressive performances of this new method.

Human conversation is the best example of loosely coupled distributed communication known to man. This study specifically considers those parts of the human conversation that show evidence of dynamism and attempts to model these parts with the objective of translating the knowledge of conversational dynamics into the domain of computerised distributed systems. The discipline of metaphorical modelling is adopted in order to create a communication framework that will maintain the aspects of dynamism and apply these design directives in distributed architectures.

Along with the rapid development of parallel computing technology and the popularity of Beowulf cluster system, the scalability of parallel algorithm-machine combinations, which measures the capacity of a parallel algorithm to effectively utilize an increasing number of processors, becomes more and more important. This ratio of parallel overhead to computation is reviewed in this paper, the merit and deficiencies of this metric are pointed out. Then in order to apply the distributed parallel computation environment based on Beowulf cluster it is improved, obtain the new extensible function which reflects the scalability of distributed parallel systems more directly and precisely when the size of machines and the scale of problems are extending in the environment of Beowulf cluster. Finally, the new metric is used to analyze and prove the scalability of parallel algorithms and Beowulf cluster.

The increase acceptance and adoption of cloud computing has seen many research projects focusing on tradition distributedcomputing issues such as resource allocation and performance. The scalability and dynamic heterogeneity of cloud computing presents a different challenge in deciding how resources are allocated to services. In this paper we identify the nature of cloud computing dynamics with virtualisation as a key part to resource allocation and meeting QoS needs. Service Level Agreement (SLA) mainly equates to actions taken when best effort falls and does not address the significant needs of meeting QoS demands as well as efficient utilisation of resources.

Scientific workflows are emerging as a dominant approach for scientists to assemble highly-specialized applications, and to exchange large heterogeneous datasets to automate the accomplishment of complex scientific tasks. Several Scientific Workflow Management Systems (SWfMS) have already been designed so as to support the execution, and monitoring of scientific workflows. Even though, there are still some additional requirements and challenges must be met in order to provide a fully distributed and efficient SWfMS. SWIMS (Scientific Workflow Management and Integration System) environment has been developed trying to examine the nature of these challenges and to accommodate the missing requirements. In this paper we are going to highlight these requirements and show how the workflow management in SWIMS fulfills them.

Cyber-physical Systems of Systems (CPSoS) are large complex systems where physical elements interact with and are controlled by a large number of distributed and networked computing elements and human users. A SoS is an integration of a finite number of constituent systems which are independent and operable, and which are networked together for a period of time to achieve a certain higher goal. In order to specify and model such kind of systems, we need develop specification and modeling methods which would be capable to encompass the systems of systems (SoS) specific properties of cyber physical systems. In this paper, we propose a new paradigm for specifying and modeling cyber physical systems based on system-of-systems approach. We propose an approach to support specification and modeling cyber physical systems based on systems of systems engineering by integrating AADL, Modelicalml and other modeling language. On the basis of the hierarchical concept of industrial CPS system, a hierarchical design scheme of industrial CPSoS system based on OPC UA heterogeneous data integration processing is proposed. This paper will also use AADL for modeling CPS on three levels: 1). robot on the unit level;2) workshops of smart factory on the system level 3) intellectual factory on the SOS level. For the physical aspect of cyber physical system, this paper will propose a method to combine modelical, Simulink and AADL model to model a unit robot which can interaction with real environment.

there're so many kinds of localization algorithms with a big localization error. And how to reduce this error is really a very important problem. This paper studies four distributed localization algorithms in WSN, and introduces a pretty popular optimization algorithm named quantum particle swarm optimization algorithm into it. In the end, this paper does some simulations with matlab. And it proves that the QPSO algorithm works well in node localization algorithm.
