the efficient and secure elliptic curve scalar multiplication can be constructed by combining the addition chain and elliptic curve. In this paper, a kind of "Double-Addition" additive chain is proposed by studying the Fibonacci sequence. the "Double-Addition" sequence of arbitrary integer k is calculated by using Fibonacci and the method of gold. In addition, each cycle of this method is fixed to perform double point and a point add operations based on the "Double-Addition" of the elliptic curve scalar multiplication algorithm, so as to be able to resist the simple power attack. At the same time, the length of the chain is greatly shortened by using the double point operation compared with the chain of the Fibonacci. Experimental results showed that the efficiency of proposed algorithm in this paper has preceded by 4% to 18% over the previous ones known in the literature and in the average chain length it has attained 38% to 55% reduction compared to other doubling-free addition chain methods.

PARRAY (or parallelizing ARRAYs) is an extension of C language that supports system-level succinct programming for heterogeneous parallel systems. Parray extends mainstream C programming with novel array types. this leads to shorter, more portable and maintainable parallel codes, while the programmer still has control over performance-related features necessary for deep manual optimization. this paper uses the case study on stepwise program refinement of matrix transposition to illustrate the basic techniques of PARRAY programming. © 2014 ifip international Federation for Information Processing.

In this paper, we present a novel stochastic analyzing model for e2e virtualized cloud services using hierarchical Quasi-Birth Death structures (QBDs). We divide the overall virtualized cloud services into three sub-hierarchies, and then, analyze each individual sub-hierarchy using QBDs. Our approach reduces the complexity of performance analysis. Our results are useful to prevent the cloud center from entering unsafe operation, and also reveal practical insights into load balancing and capacity planning for virtualized computing environments. © 2014 ifip international Federation for Information Processing.

Modern datacenters rely heavily on virtualization technologies to offer customized computing and network resources on demand to a large number of tenant applications. However, efficiency in resource utilization delivered by virtualization technologies that exploit statistical multiplexing of resources across applications means that predictability in performance remains a challenge. Allocation of network bandwidth is particularly difficult, given the variability of traffic flows between the components of multi-tier applications. Static bandwidth allocation based on peak traffic rates ensures SLA compliance at the cost of significant overprovisioning, while allocation based on mean traffic rates ensures efficient usage of bandwidth at the cost of QoS violations. We describe MAPLE, a network-aware VM ensemble placement scheme that uses empirical estimations of the effective bandwidth required between servers to ensure that QoS violations are within targets specified in the SLA for the tenant application. Experimental results obtained using traffic traces collected from an emulated datacenter show that, in contrast to the Oktopus network-aware VM placement system, MAPLE is able to allocate computing and network resources in a manner that balances efficiency of resource utilization with performance predictability.

Let us consider an upper bounded number of data streams to be processed by a Divisible Load application. the total workload is unknown and the available speeds for communicating and computing may be poorly a priori estimated. this paper presents a resource selection method that aims at maximizing the throughput of this processing. From a set of processing units linked by a network, this method consists in forming an optimal set of master-workers clusters. Results of simulations are presented to assess the efficiency of this method experimentally. Before focusing on the proposed resource selection method, the paper comes back on the adaptive scheduling method on which it relies.

In a cloud computing environment, virtual machine allocation is an important task for providing infrastructure services. Generally, the datacenters, on which a cloud computing platform runs, are distributed over a wide area network. therefore, communication cost should be taken into consideration when allocating VMs across servers of multiple datacenters. A network-aware VM allocation algorithm for cloud is developed. It tries to minimize the communication cost and latency between servers, with the number of VMs, VM configurations and communication bandwidths are satisfied to users. Specifically, a two-dimensional knapsack algorithm is applied to solve this problem. the algorithm is evaluated and compared with other ones through experiments, which shows satisfying results.

the growing size of the multiprocessor system increases its vulnerability to component failures. the fault diagnosis is the process of identifying faulty processors in a system through self-testing, and the diagnosability is an important parameter to measure the reliability of an interconnection network. As a new measure of fault tolerance, conditional diagnosability can better evaluate the real diagnosability of interconnection networks. In this paper, we derive the conditional diagnosability of the multiprocessor systems in terms of Complete Josephus Cubes CJC(n) (n >= 8) under the comparison model.

DCell has been proposed for one of the most important data center networks as a server centric data center network structure. DCell can support millions of servers with outstanding network capacity and provide good fault tolerance by only using commodity switches. In this paper, we prove that there exist r vertex disjoint paths {P(i vertical bar)1 <= i <= r} between any two distinct vertices u and v of DCell(k) (k >= 0) where r = n + k - 1 and n is the vertex number of DCell(0). the result is optimal because of any vertex in DCell(k) has r neighbors with r = n + k - 1.

As a new kind of commercial model, cloud computing can integrate various kinds of resources in the network. Resource providers offer these resources to users in the form of service and receive corresponding profits. To make more rational use of the cloud resources, an effective mechanism is necessary for allocating the resources. In this paper, the price attribution and non-price attributions of both traders are analyzed. the support vector machine algorithm is utilized to predict the price, further determining the quote and bid. then, the BP neural network algorithm is used to transfer the non-price attributions to the quality index. Finally, to maximize the total satisfaction of resource providers and resource consumers, the mean-variance optimization algorithm is adopted to obtain the optimized cloud resource allocation scheme. Simulation results have shown that the proposed mechanism is feasible and effective.
