Some typical memory access patterns are provided and programmed in C, which can be used as benchmark to characterize the various techniques and algorithms aim to improve the performance of NUMA memory access. These access patterns, called MAP-numa (Memory Access Patterns for NUMA), currently include three classes, whose working data sets are corresponding to 1-dimension array, 2-dimension matrix and 3-dimension cube. It is dedicated for NUMA memory access optimization other than measuring the memory bandwidth and latency. MAP-numa is an alternative to those exist benchmarks such as STREAM, pChase, etc. It is used to verify the optimizations' (made automatically/manually to source code/executive binary) capacities by investigating what locality leakage can be remedied. Some experiment results are shown, which give an example of using MAP-numa to evaluate some optimizations based on Oprofile sampling. © IFIP International Federation for Information Processing 2012.

This paper considers the problem of task assignment in heterogeneous distributed computing systems with the goal of minimizing the total execution and communication costs. An iterated local search algorithm is proposed for finding the suboptimal task assignment in a reasonable amount of computation time. We study the performance of the proposed algorithm over a wide range of parameters such as the problem scales, the ratio of average communication time to average computation time, and task interaction density of applications. The effectiveness of the algorithm is manifested by comparing it with other competing algorithms in the relevant literature. © (2012) Trans Tech Publications, Switzerland.

Real-time depth of field (DoF) rendering is crucial to realistic image synthesis and VR applications. This paper presents a new method to simulate the depth-of-field effects with bilateral depth filtering. Unlike the traditional rendering methods that handle the depth-of-field with Gaussian filtering, we develop a new DoF filter, called adaptive bilateral depth filter, to adaptively postfilter the pixels according to their depth variance. Depth information is used to focus on the objects with edge-preserving property. Our approach can eliminate the artifacts of intensity leakage, which can generate adaptive high-quality DoF rendering effects dynamically, and can be fully implemented in GPU parallelization. © 2012 Springer-Verlag.

ATE: Anti-malware technique evaluator

Information Security for South Africa (ISSA)

作者： Manuel Corregedor Sebastiaan Von Solms Academy of Computer Science and Software Engineering Johannesburg South Africa

Current commercial anti-malware products fail to guarantee a 100% detection and prevention of malware. This paper proposes an evaluation framework called ATE (Anti-malware Technique Evaluator) that can be used to evaluate commercial anti-malware products. ATE identifies the vulnerabilities in anti-malware products by providing a set of requirements that must be fulfilled by the anti-malware product being evaluated. The ATE requirements used for evaluating anti-malware products go beyond the usual false positives, false negative, performance etc requirements employed by current anti-malware product evaluations.

For a successful software project, acceptable quality must be achieved within an acceptable cost, demonstrating business value to customers and satisfactorily meeting delivery timeliness. Testing serves as the most widely used approaches to determine that the intended functionalities are performed correctly and achieve the desired level of services;however, it is also a labor-intensive and expensive process during the whole software life cycle. Most current testing processes are often technique-centered, rather than organized to maximize business value. In this article, we extend and elaborate the '4+1' theoretical lenses of Value-based software engineering (VBSE) framework in the software testing process;propose a multi-objective feature prioritization strategy for testing planning and controlling, which aligns the internal testing process with value objectives coming from customers and markets. Our case study in a real-life business project shows that this method allows reasoning about the software testing process in different dimensions: it helps to manage the testing process effectively and efficiently, provides information for continuous internal software process improvement, and increases customer satisfaction, which makes winners of all success-critical stakeholders (SCSs) in the software testing process.

LLE is a nonlinear dimensionality reduction method, which has been successfully applied to data visualization. Based on the assumption of local linearity, LLE can compute the weights between the KNN nodes using the local least reconstruction errors, which increase the computational cost. In this paper, a method titled Discriminant Graph Based Linear Embedding (DGBLE) is proposed to set the weights between the nodes in the KNN graph directly to reduce the computational expense. Moreover, label information can also be taken into account to improve the discriminant power of the original LLE. Experiments on some benchmark data show that the proposed method is feasible and effective. © 2012 Springer-Verlag.

When clients store large files on a remote network of unreliable distributed servers, they want to verify that their files are properly stored in the servers without any modification. This can be achieved by the techniques of data integrity. In this paper, we consider how to implement data integrity check by a third party auditor (TPA) in a distributed storage network, with the help of BLS signature. We also consider how the distributed storage network restores data when some server fails or some server crushes down. We present a data integrity check and repair (DICR) scheme, which makes use of a random (n, k) linear code for data restoration and BLS signature to implement data integrity check. Our scheme is robust in the way that the storage network can reconstruct the data when a limited number of servers fail. In the mean time, public auditing on the storage network liberates clients from computational overhead. © (2012) Trans Tech Publications, Switzerland.

International Conference on Availability, Reliability and Security, ARES

作者： Marijke Coetzee Academy of Computer Science and Software Engineering University of Johannesburg South Africa

Service Oriented Architecture (SOA) is a design paradigm that enables applications to be built from business processes to support enterprise architecture. This architecture introduces information security challenges that are not comprehensively addressed by current best-practices. This paper evaluates if an Information Security Management System (ISMS), defined by the international standard ISO/IEC 27001 and 27002 can be used to comprehensively support Information Security governance for SOA. As SOA governance, a separate and distinct governance framework, also addresses information security to a certain extent, managers are faced the difficult task of deciding whether their SOA sufficiently protected by the different frameworks. The conclusion is that information security for SOA needs to be addressed more holistically, following an Enterprise Information Security Architecture (EISA) approach where Enterprise Architecture (EA) is concerned with the design of the overall architectural vision of an organization. The framework chosen for this purpose is SABSA, a well-known enterprise security architecture. Using the example of access control to highlight challenges, it becomes clear that Information Security governance for SOA can benefit from an approach such as SABSA.

The advance of the Internet in the past decade has radically changed the way people communicate and col- laborate with each other. Physical distance is no more a barrier in online social networks, but cultural differences （at the individual, community, as well as societal levels） still govern human-human interactions and must be con- sidered and leveraged in the online world. The rapid deployment of high-speed lnternet allows humans to interact using a rich set of multimedia data such as texts, pictures, and videos. This position paper proposes to define a new research area called ＇connected multimedia＇, which is the study of a collection of research issues of the super-area social media that receive little attention in the literature. By connected multimedia, we mean the study of the social and technical interactions among users, multimedia data, and devices across cultures and explicitly exploiting the cultural differences. We justify why it is necessary to bring attention to this new research area and what benefits of this new research area may bring to the broader scientific research community and the humanity.
