Software platform Virtualization in chemistry research and university teaching
Journal of Cheminformatics, 2009Co-Authors: Tobias Kind, Tim Leamy, Julie A Leary, Oliver FiehnAbstract:Modern chemistry laboratories operate with a wide range of Software applications under different operating systems, such as Windows, LINUX or Mac OS X. Instead of installing Software on different computers it is possible to install those applications on a single computer using Virtual Machine Software. Software platform Virtualization allows a single guest operating system to execute multiple other operating systems on the same computer. We apply and discuss the use of virtual machines in chemistry research and teaching laboratories. Virtual machines are commonly used for cheminformatics Software development and testing. Benchmarking multiple chemistry Software packages we have confirmed that the computational speed penalty for using virtual machines is low and around 5% to 10%. Software Virtualization in a teaching environment allows faster deployment and easy use of commercial and open source Software in hands-on computer teaching labs. Software Virtualization in chemistry, mass spectrometry and cheminformatics is needed for Software testing and development of Software for different operating systems. In order to obtain maximum performance the Virtualization Software should be multi-core enabled and allow the use of multiprocessor configurations in the virtual machine environment. Server consolidation, by running multiple tasks and operating systems on a single physical machine, can lead to lower maintenance and hardware costs especially in small research labs. The use of virtual machines can prevent Software virus infections and security breaches when used as a sandbox system for internet access and Software testing. Complex Software setups can be created with virtual machines and are easily deployed later to multiple computers for hands-on teaching classes. We discuss the popularity of bioinformatics compared to cheminformatics as well as the missing cheminformatics education at universities worldwide.

Coalitional Game for the Creation of Efficient Virtual Core Network Slices in 5G Mobile Systems
IEEE Journal on Selected Areas in Communications, 2018Co-Authors: Miloud Bagaa, Adlen Ksentini, Tarik Taleb, Abdelquoddouss Laghrissi, Hannu FlinckAbstract:Many ongoing research activities relevant to 5G mobile systems concern the Virtualization of the mobile core network, including the evolved packet core (EPC) elements, aiming for system scalability, elasticity, flexibility, and cost-efficiency. Virtual EPC (vEPC)/5G core will principally rely on some key technologies, such as network function Virtualization, Software defined networking, and cloud computing, enabling the concept of mobile carrier cloud. The key idea beneath this concept, also known as core network as a service, consists in deploying virtual instances (i.e., virtual machines or containers) of key core network functions [i.e., virtual network functions (VNF) of 4G or 5G], such as the mobility management entity (MME), Serving GateWay (SGW), Packet Data network gateWay (PGW), access and mobility management function (AMF), session management function (SMF), authentication server function (AUSF), and user plane functions, over a federated cloud. In this vein, an efficient VNF placement algorithm is highly needed to sustain the quality of service (QoS) while reducing the deployment cost. Our contribution in this paper is twofold. First, we devise an algorithm that derives the optimal number of virtual instances of 4G (MME, SGW, and PGW) or 5G (AMF, SMF, and AUSF) core network elements to meet the requirements of a specific mobile traffic. Second, we propose an algorithm for the placement of these virtual instances over a federated cloud. While the first algorithm is based on mixed integer linear programming, the second is based on coalition formation game, wherein the aim is to build coalitions of cloud networks to host the virtual instances of the vEPC/5G core elements. The obtained results clearly indicate the advantages of the proposed algorithms in ensuring QoS given a fixed cost for vEPC/5G core deployment, while maximizing the profits of cloud operators.
