The GENERTIA red team uses a genetic algorithm to perform vulnerability analysis in an effort to discover holes in an intrusion detection system. This paper demonstrates how a GENERTIA blue team generates detectors to patch those holes discovered by the GRT, The GBT uses a novel approach to generate detectors that have different coverage in order to reduce the amount of overlap of detectors created by random generation and negative selection.

Multiscale Modeling of Materials-2000

作者： Andia, P.C. Costanzo, F. Gray, G.L. Yurick, T.J. Lab. Parallel Computational Mech. Eng. Science and Mechanics Dept. The Pennsylvania State University University Park PA 16802 United States

An approach is presented for the determination of the residual stresses and elastic moduli of particle systems resulting from computer simulations of particle or atomic deposition. The proposed technique is based on fundamental concepts of elasticity and is capable of capturing the variation of stresses and moduli as functions of position within the system. Application to a simple particle system consisting of a deposited thin film is demonstrated.

Facing the large-scale, heterogeneous dynamic resource and the complex constraints of computation-intensive parallel scientific applications, collab.rating large-scale computation resource for these applications within Large-Scale Distributed Computing Infrastructures like grids and clouds are challenging. This paper addresses this issue by proposing a Resource Capability Model and implementing a corresponding language GSO and an information service Application Information Service to ensure not only the resource description, aggregation, matchmaking but also life cycle management of the reservations and tasks. Experiment result shows that our mechanism is scalab.e in both Grid and Cloud environment. © Institute for Computer sciences, Social Informatics and Telecommunications Engineering 2014.

We report our work on evaluating performance of several MPI Allgather algorithms on Fast Ethernet. These algorithms are ring, recursive doubling, Bruck, and neighbor exchange. The first three algorithms are widely used today. The neighbor exchange algorithm which was recently proposed by the authors incorporates pair-wise exchange, and is expected to perform better with certain configurations, mainly when using TCP/IP over Ethernet. We tested the four algorithms on terascale Linux clusters DeepComp 6800 and DAWNING 4000A using TCP/IP over Fast Ethernet. Results show that our neighbor exchange algorithm performs the best for long messages, the ring algorithm performs the best for medium-size messages and the recursive doubling algorithm performs the best for short messages.

International Review on Computers and software 2012年第4期7卷 1541-1546页

In National Earthquake Precursory (NEP) industry, massive device resources are distributed in agencies and administrations and their communication method, command set and hardware performance are heterogeneous. It is emergent to make all the device resources availab.e and dependable to the whole system. To access these resources effectively and reliably has become one of the urgent problems of the NEP industry. Faced with the need of effective device resources access and QoS guarantee, we propose a mechanism of Device Collab.ration Middleware based on QoS and implement the device source middleware in NEP. Experiments show that our middleware performs well in whole NEP. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.

Sparse matrix-vector multiplication (SpMV) is an important kernel in many scientific applications and is known to be memory bandwidth limited. On modern processors with wide SIMD and large numbers of cores, we identify and address several bottlenecks which may limit performance even before memory bandwidth: (a) low SIMD efficiency due to sparsity, (b) overhead due to irregular memory accesses, and (c) load-imbalance due to non-uniform matrix structures. We describe an efficient implementation of SpMV on the Intel® Xeon Phi™ Coprocessor, codenamed Knights Corner (KNC), that addresses the above challenges. Our implementation exploits the salient architectural features of KNC, such as large caches and hardware support for irregular memory accesses. By using a specialized data structure with careful load balancing, we attain performance on average close to 90% of KNC's achievable memory bandwidth on a diverse set of sparse matrices. Furthermore, we demonstrate that our implementation is 3.52x and 1.32x faster, respectively, than the best availab.e implementations on dual Intel® Xeon™ Processor E5-2680 and the NVIDIA Tesla K20X architecture. © 2013 ACM.

This chapter presents a formalization of functional and behavioural requirements, and a refinement of requirements to a design for CoCoME using the Relational Calculus of Object and Component Systems (rCOS). We give a model of requirements based on an abstraction of the use cases described in Chapter 3.2. Then the refinement calculus of rCOS is used to derive design models corresponding to the top level designs of Chapter 3.4. We demonstrate how rCOS supports modelling different views and their relationships of the system and the separation of concerns in the development. © 2008 Springer-Verlag Berlin Heidelberg.

GPU is the mainstream co-processor computers of heterogeneous architecture. parallel graph algorithms are fundamental for many data-driven applications to be solved on heterogeneous clusters. SSSP (Single Source Shortest Path) algorithm is one of the most important one. We proposed a graph representation structure with unified vertex’s degree. This method ensures the data block size consistency. And then, the transferring in memory on this representation makes the data reading in cohesion for CUDA thread blocks. Thirdly, vertex renumbering optimizes the locality of graph vertices to make the relaxing operation more efficient. With data of New York road, we implemented SSSP algorithms of delta-stepping on Nvida Tesla K20x GPU device. The experimental results show that the best unified-degree is approximate to the mode of vertex-degree of the graph. For example of the New York road map, all degrees were unified into 4-degree that results to the biggest speed-up of SSSP algorithm. © Springer International Publishing Switzerland 2015.

With the rapid development of highperformance computing, computational fluid dynamics (CFD) has become an important part of hydrodynamics and aerodynamics. Mesh quality is the key factor that affects the accuracy and efficiency of CFD numerical calculation. However, the current the process of mesh quality discrimination is very time-consuming. The manpower time needed for this process takes up a large proportion in the whole numerical calculation process. A large number of artificial intelligence algorithms have been put forward to replace the human to efficiently complete all kinds of tedious tasks. In this paper, we propose a convolutional neural network (CNN) based mesh quality discrimination method, MeshNet. MeshNet uses residual neural network structure to learn mesh features and automatically judge the mesh quality. The experimental results show that the proposed network can greatly save lab.r time cost and achieve an accuracy of 94.41% for mesh quality discrimination. © 2020 IEEE.
