TL;DR: A new fuzzy-logic trust model for securing Grid resources by enhancing the trust index of resource sites by upgrading their intrusion defense capabilities and checking the success rate of jobs running on the platforms is proposed.
Abstract: How to build the mutual trust among Grid resources sites is crucial to secure distributed Grid applications. We suggest enhancing the trust index of resource sites by upgrading their intrusion defense capabilities and checking the success rate of jobs running on the platforms. We propose a new fuzzy-logic trust model for securing Grid resources. Grid security is enforced through trust update, propagation, and integration across sites. Fuzzy trust integration reduces platform vulnerability and guides the defense deployment across Grid sites. We developed a SeGO scheduler for trusted Grid resource allocation. The SeGO scheduler optimizes the aggregate computing power with security assurance under fixed budget constraints. The effectiveness of the scheme was verified by simulation experiments. Our results show up to 90% enhancement in site security. Compared with no trust integration, our scheme leads to 114% improvement in Grid performance/cost ratio. The job drop rate reduces by 75%. The utilization of Grid resources increased to 92.6% as more jobs are submitted. These results demonstrate significant performance gains through optimized resource allocation and aggressive security reinforcement.

TL;DR: AFGPGA method based on GPU-acceleration, which maps parallel GA algorithm to texture-rendering on consumer-level graphics cards is proposed, which increases the population size, speeds up its execution and provides ordinary users with a feasible FGPGA solution.
Abstract: Fine-grained parallel genetic algorithm (FGPGA), though a popular and robust strategy for solving complicated optimization problems, is sometimes inconvenient to use as its population size is restricted by heavy data communication and the parallel computers are relatively difficult to use, manage, maintain and may not be accessible to most researchers. In this paper, we propose a FGPGA method based on GPU-acceleration, which maps parallel GA algorithm to texture-rendering on consumer-level graphics cards. The analytical results demonstrate that the proposed method increases the population size, speeds up its execution and provides ordinary users with a feasible FGPGA solution.

TL;DR: This work proposes a novel fine-grained benchmarking approach and applies it on two popular GPUs, namely Fermi and Kepler, to expose the previously unknown characteristics of their memory hierarchies, and investigates the structures of different cache systems.
Abstract: Memory access efficiency is a key factor for fully exploiting the computational power of Graphics Processing Units (GPUs) However, many details of the GPU memory hierarchy are not released by the vendors We propose a novel fine-grained benchmarking approach and apply it on two popular GPUs, namely Fermi and Kepler, to expose the previously unknown characteristics of their memory hierarchies Specifically, we investigate the structures of different cache systems, such as data cache, texture cache, and the translation lookaside buffer (TLB) We also investigate the impact of bank conflict on shared memory access latency Our benchmarking results offer a better understanding on the mysterious GPU memory hierarchy, which can help in the software optimization and the modelling of GPU architectures Our source code and experimental results are publicly available

TL;DR: An energy aware degree-based transmission power control protocol is presented, augmenting its distributed protocol with a heuristic that considers neighbor load information when making power control decisions, which can improve energy efficiency and prolong network lifetime significantly, while networks connectivity is still maintained in extreme scenarios.
Abstract: Topology control in wireless networks is important to maintain reliable communication links between base stations and nodes, and to maximize the battery life. This paper analyzes how the power control technology affects the MAC layer, network topology, routing, and energy efficiency. Then an energy aware degree-based transmission power control protocol is presented in this paper. We augment our distributed protocol with a heuristic that considers neighbor load information when making power control decisions. It limits the accretion of transmission power, particularly in loose network. Compared to traditional protocol, our protocol can improve energy efficiency and prolong network lifetime significantly, while networks connectivity is still maintained in extreme scenarios. Simulation results demonstrate our conclusion.

TL;DR: A study of architectural styles for the reference architecture of SOC-based software systems, and a classification scheme for the architecture styles extracted from existing research projects and industry practices are proposed.
Abstract: Architecting service-oriented systems is a complex design activity. It involves making trade-offs among a number of interdependent design decisions, which are drawn from a range of concerns by various software stakeholders. In order to achieve effective and efficient SOC design we believe a careful study of architectural styles that can form the reference architecture is important. Hence, this paper provides a study of architectural styles for the reference architecture of SOC-based software systems. We propose a classification scheme for the architecture styles. These architectural styles are extracted from existing research projects and industry practices based on our classification scheme. For all those identified styles, we present an evolution trend driven by engineering principles for Internet-scale systems. As a result, this paper moves the first step towards creating a Reference Architecture that can be utilised to provide sensible guidance on the design of Web services application architecture.
