Viral marketing on social networks is an important application and hot research problem. Most of the related work on viral marketing focuses on the spread of single information, while a product may associate with multi-attribute in real life. Information on multiple attributes of a product propagates in the social networks simultaneously and independently. The attribute information that a user receives will determine whether he would purchase the product or not. We extend the traditional single information influence maximization problem to the Multi-attribute based Influence Maximization Problem (MIMP). We present the Multi-dimensional IC model (MIC model) for the proposed problem. The objective function for MIMP is proved to be non-submodular, then we solve the problem with the Sandwich Algorithm, which can get a max{f(SU)f¯(SU),f̲(SL∗)f(So∗)}(1-1/e) approximation ratio to the optimal solution. Experiments are conducted in two real world datasets to verify the correctness and effectiveness of the proposed algorithm. © 2021, Springer Nature Switzerland AG.

In the Top500 and Graph500 lists of the last years, some of the most powerful systems implement a torus topology to interconnect the millions of computing nodes they include. Some of these torus networks are of five or six dimensions, which implies an additional difficulty as the node degree increases. In previous works, we proposed and evaluated the nD Twin (nDT) torus topology to virtually increase the dimensions a torus is able to implement. We showed that this new topology reduces the distances between nodes, increasing, therefore, global network performance. In this work, we present how to build a 5DT torus network using a specific commercial 6-port network card (EXTOLL card) to interconnect those nodes. We show, using the same number of cards, that the performance of the 5DT torus network we are able to implement using our proposal is higher than the performance of the 3D torus network for the same number of compute nodes. © 2017 John Wiley & Sons, Ltd.

To meet the expected performance requirements of applications running on future exascale systems, the number of processing nodes included in such systems will have to increase and, according to the current trend, also the number of cores in each node. In these systems, the networks, both off-and on-chip, interconnecting these nodes and cores inside nodes, respectively, will have to be much more efficient than current ones. In order to develop and research on interconnection networks, simulation is the most common technique used. Simulators traditionally have used synthetic traffic as network workload which does not represent the network workload that real applications generate. The use of application communication trace files is a best strategy for this purpose. In this paper, we extend an existing tool including functionality related to communication within each node. In this way, the tool will allow interconnection network simulators to model traffic due to all the communications generated in the exascale systems. © 2018 IEEE.

Background: systems Medicine is a novel approach to medicine, that is, an interdisciplinary field that considers the human body as a system, composed of multiple parts and of complex relationships at multiple levels, and further integrated into an environment. Exploring systems Medicine implies understanding and combining concepts coming from diametral different fields, including medicine, biology, statistics, modeling and simulation, and data science. Such heterogeneity leads to semantic issues, which may slow down implementation and fruitful interaction between these highly diverse fields. Methods: In this review, we collect and explain more than100 terms related to systems Medicine. These include both modeling and data science terms and basic systems medicine terms, along with some synthetic definitions, examples of applications, and lists of relevant references. Results: This glossary aims at being a first aid kit for the systems Medicine researcher facing an unfamiliar term, where he/she can get a first understanding of them, and, more importantly, examples and references for digging into the topic. © Massimiliano Zanin et al., 2021;Published by Mary Ann Liebert, Inc. 2021.

Several of the most powerful supercomputers in the Top500 and the Graph500 lists continue choosing a torus topology to interconnect a large number of compute nodes. In some cases, a torus network with five or six dimensions is implemented, however, one notices that the costs of implementing an interconnection network increase with the node degree. In previous works we defined and characterized the nD Twin (nDT) torus topology in order to virtually increase the dimensionality of a torus. This new topology reduces the distances between nodes and therefore increases network performance. In this work, we present how to build a 5DT torus network using commercial 6-port network cards. The main issues of this approach are detailed, and we present solutions these problems. Moreover we show, using the same components, that the performance of the 5DT torus network is higher than the performance of the 3D torus network for the same number of compute nodes.

IEEE International Conference on Cluster Computing

Simulation is often used to evaluate the behaviour and measure the performance of computing systems. Specifically, in high-performance interconnection networks, the simulation has been extensively considered to verify the behaviour of the network itself and to evaluate its performance. In this context, network simulation must be fed with network traffic, also referred to as network workload, whose nature has been traditionally synthetic. These workloads can be used for the purpose of driving studies on network performance, but often such workloads are not accurate enough if a realistic evaluation is pursued. For this reason, other non-synthetic workloads have gained popularity over last decades since they are best to capture the realistic behaviour of existing applications. In this paper, we present the VEF traces framework, a self-related trace model, and all their associated tools. The main novelty of this framework is that, unlike existing ones, it does not provide a network simulation framework, but only offers an MPI task simulation framework, which allows one to use the MPI-based network traffic by any third-party network simulator, since this framework does not depend on any specific simulation platform.

Optimal Configuration for N-Dimensional Twin Torus Networks

Optimal Configuration for N-Dimensional Twin Torus Networks

IEEE International Symposium on Network Computing and Applications

作者： Francisco J. Andújar Juan A. Villar José L. Sánchez Francisco J. Alfaro José Duato Computing Systems Department University of Castilla-La Mancha Albacete Spain Dep. of Systems Data Processing and Computers Technical University of Valencia Valencia Spain

Torus topology is one of the most common topologies used in the current largest supercomputers. Although 3D torus is widely used, recently some supercomputers in the Top500 list have been built using networks with topologies of five or six dimensions. To obtain an nD torus, 2n ports per node are needed. These ports can be offered by a single or several cards per node. In the second case, there are multiple ways of assigning the dimension and direction of the card ports. In a previous work we proposed the 3D Twin (3DT) torus which uses two 4-port cards per node, and obtained the optimal port configuration. This paper extends and generalizes that work in order to obtain the optimal port configuration when n dimensions are considered. Thus, the nDT torus topology is presented and defined, and a detailed formal analysis leads to the optimal port configuration. Finally, performance results are included.

This paper describes an approach to segment and locate people in crowded scenarios with application to a surveillance system for airport dependencies. To obtain robust operation, the system analyzes a variety of visual cues -color, motion and shape- and integrates them optimally. A general method for automatic inference of optimal cue integration rules is presented. This schema, based on supervised training on video sequences, avoids the need of explicitly formulate combination rules based on a-priori constraints. The performance of the system is at least as good as classical fusing strategies like those based on voting, because the optimized decision engine implicitly includes these and other strategies.
