“…Unfortunately, such a machine was not available to us at the time of our experiment. Alternatively, we were able to use one of the methods that emulate multi-core machines [18]. In our experiment, we emulated the multi-core machine with nine machines.…”

In this paper, we propose a novel block cipher mode of operation, which is known as the counter chain (CC) mode. The proposed CC mode integrates the cipher block chaining (CBC) block cipher mode of operation with the counter (CTR) mode in a consistent fashion. In the CC mode, the confidentiality and authenticity of data are assured by the CBC mode, while speed is achieved through the CTR mode. The proposed mode of operation overcomes the parallelization deficiency of the CBC mode and the chaining dependency of the counter mode. Experimental results indicate that the proposed CC mode achieves the encryption speed of the CTR mode, which is exceptionally faster than the encryption speed of the CBC mode. Moreover, our proposed CC mode provides better security over the CBC mode. In summary, the proposed CC block cipher mode of operation takes the advantages of both the Counter mode and the CBC mode, while avoiding their shortcomings.

“…This is both an advantage (faster networks and CPUs can be emulated) and a disadvantage (if more control over the device speed is needed). The approach used in Distem (based on [3]) is more simple and more robust, but is limited to reducing the performance -it cannot be used to emulate faster machines.…”

International audienceBetween simulation and experiments on real-scale testbeds, the combined use of emulation and virtualization provide a useful alternative for performing experiments on distributed systems such as clusters, grids, cloud computing or P2P systems. In this paper, we present Distem, a software tool to build distributed virtual experimental environments. Using an homogenenous set of nodes, Distem emulates a platform composed of heterogeneous nodes (in terms of number and performance of CPU cores), connected to a virtual network described using a realistic topology model. Distem relies on LXC, a low-overhead container-based virtualization solution, to achieve scalability and enable experiments with thousands of virtual nodes. Distem provides a set of user interfaces to accomodate different needs (command-line for interactive use, Ruby and REST APIs), is freely available and well documented. After a detailed description of Distem, we perform an experimental evaluation of several of its features.Entre la simulation et l'expérimentation sur des plates-formes réelles, l'usage combiné de l'émulation et de la virtualisation fournit une alternative utile pour réaliser des expériences sur des systèmes distribués tels que les clusters, grilles, le Cloud ou les systèmes P2P. Dans cet article, nous présentons Distem, un logiciel permettant de construire des environnements expérimentaux distribués virtuels. À partir d'un ensemble homogène de noeuds, Distem émule une plate-forme composée de noeuds hétérogènes (en termes de nombre et de performance de leurs coeurs CPU), connectés à un réseau virtuel décrit à partir d'un modèle de topologies réaliste. Distem se base sur LXC, une solution de virtualisation légère à base de conteneurs, pour obtenir des propriétés de passage à l'échelle satisfaisantes et permettre des expériences avec des milliers de noeuds virtuels. Distem fournit plusieurs interfaces utilisateurs permettant de s'adapter à différents besoins (ligne de commande pour l'usage interactif, Ruby, API REST), est librement disponible et bien documenté. Après une description détaillée de Distem, cet article présente une validation expérimentale de plusieurs de ses fonctionnalités

“…Traditional EMT simulation is limited by the computing power of the simulation platform and the parallel structure of the simulation algorithm. However, in recent years, with the emergence of high-performance computing platforms, EMT simulation platforms have developed from single computer to computer cluster [4], from multi-core CPU [5] to GPU-based [6,7] or FPGA-based [8] heterogeneous computing. The development of the simulation platforms greatly improves the calculation speed of the model and the simulation efficiency of the power systems.…”

With the interconnection of regional grids and the increasing penetration of renewable energy, the order of the power system model is getting higher and higher, which brings great challenges to the accuracy and real-time performance of electromagnetic transient (EMT) simulation. The simulation of power systems with a high proportion of renewable energy requires a sharp increase in the performance of the hardware platform and the parallelism of the simulation algorithm. To solve this problem, the paper proposes a finegrained parallel modelling method for power systems with a high proportion of renewable energy, which is inspired by the latency insertion method used in the design of large-scale integrated circuits. And this method is implemented on GPU to achieve the componentlevel and device-level parallelized simulation of power systems with a high proportion of renewable energy. Finally, the correctness of the proposed algorithm and the CPU-GPU cooperative architecture is verified based on an improved 118-bus case. The cascade system of the improved 9-bus case is used as an example to verify the superiority of the proposed algorithm in terms of simulation efficiency.
