Recently, Gajarský et al. proposed a new parameter called modular-width using the notion of modular decomposition of graphs. They showed that the chromatic number problem and the partitioning into paths problem, and hence hamiltonian path and hamiltonian cycle, are FPT when parameterized by this parameter. In this paper, we study modular-width in parameterized parallel complexity and show that the weighted maximum clique problem and the maximum matching problem are fixed-parameter parallel-tractable (FPPT) when parameterized by this parameter."}],"language":[{"iso":"eng"}],"series_title":"LNCS","doi":"10.1007/978-3-319-59605-1_13","author":[{"first_name":"Faisal N.","last_name":"Abu-Khzam","full_name":"Abu-Khzam, Faisal N."},{"full_name":"Li, Shouwei","first_name":"Shouwei","last_name":"Li"},{"id":"37612","full_name":"Markarian, Christine","last_name":"Markarian","first_name":"Christine"},{"id":"15523","full_name":"Meyer auf der Heide, Friedhelm","last_name":"Meyer auf der Heide","first_name":"Friedhelm"},{"last_name":"Podlipyan","first_name":"Pavel","full_name":"Podlipyan, Pavel"}],"year":"2017","title":"Modular-Width: An Auxiliary Parameter for Parameterized Parallel Complexity","date_updated":"2022-01-06T07:03:52Z","citation":{"bibtex":"@inproceedings{Abu-Khzam_Li_Markarian_Meyer auf der Heide_Podlipyan_2017, series={LNCS}, title={Modular-Width: An Auxiliary Parameter for Parameterized Parallel Complexity}, DOI={<a href=\"https://doi.org/10.1007/978-3-319-59605-1_13\">10.1007/978-3-319-59605-1_13</a>}, booktitle={Proceedings of the 11th International Workshop on Frontiers in Algorithmics (FAW)}, author={Abu-Khzam, Faisal N. and Li, Shouwei and Markarian, Christine and Meyer auf der Heide, Friedhelm and Podlipyan, Pavel}, year={2017}, pages={139–150}, collection={LNCS} }","ama":"Abu-Khzam FN, Li S, Markarian C, Meyer auf der Heide F, Podlipyan P.

For the analysis, this opens up two possibilities: building generic, policy independent and building specific, policy dependent IFAs. While the former needs to track all dependencies between program entities, the latter allows for a reduced and thus more efficient analysis.\r\n\r\nIn this paper, we start out by formally defining a policy independent information flow analysis. Next, we show how to specialize this IFA via policy specific variable tracking, and prove soundness of the specialization. We furthermore investigate refinement relationships between policies, allowing an IFA for one policy to be employed for its refinements. As policy refinement depends on concrete program entities, we additionally propose a precomputation of policy refinement conditions, enabling an efficient refinement check for concrete programs.","lang":"eng"}],"publication":"Formal Methods and Software Engineering - 19th International Conference  on Formal Engineering Methods (ICFEM 2017)"},{"issue":"2","publication":"International Journal of Network Management","abstract":[{"lang":"eng","text":"Network function virtualization and software-defined networking allow services consisting of virtual network functions to be designed and implemented with great flexibility by facilitating automatic deployments, migrations, and reconfigurations for services and their components. For extended flexibility, we go beyond seeing services as a fixed chain of functions. We define the service structure in a flexible way that enables changing the order of functions in case the functionality of the service is not influenced by this, and propose a YANG data model for expressing this flexibility. Flexible structures allow the network orchestration system to choose the optimal composition of service components that for example gives the best results for placement of services in the network. When number of flexible services and number of components in each service increase, combinatorial explosion limits the practical use of this flexibility. In this paper, we describe a selection heuristic that gives a Pareto set of the possible compositions of a service as well as possible combinations of different services, with respect to different optimization objectives. Moreover, we present a heuristic algorithm for placement of a combination of services, which aims at placing service components along shortest paths that have enough capacity for accommodating the services. By applying these solutions, we show that allowing flexibility in the service structure is feasible."}],"date_created":"2017-10-17T12:41:02Z","file":[{"relation":"hidden","date_updated":"2018-06-13T09:15:42Z","file_name":"58-preprint-ijnm.pdf","file_size":2765738,"access_level":"open_access","file_id":"1579","content_type":"application/pdf","creator":"florida","date_created":"2018-03-21T13:18:13Z"},{"creator":"sevilmeh","date_created":"2018-06-13T09:22:37Z","access_level":"open_access","file_size":2766920,"file_name":"58-accepted-ijnm.pdf","date_updated":"2018-06-13T09:22:37Z","relation":"main_file","content_type":"application/pdf","file_id":"3197"}],"department":[{"_id":"75"}],"type":"journal_article","author":[{"first_name":"Sevil","last_name":"Dräxler","full_name":"Dräxler, Sevil","id":"31764"},{"id":"126","first_name":"Holger","last_name":"Karl","full_name":"Karl, Holger"}],"title":"Specification, Composition, and Placement of Network Services with Flexible Structures","year":"2017","date_updated":"2022-01-06T07:02:42Z","doi":"10.1002/nem.1963","citation":{"bibtex":"@article{Dräxler_Karl_2017, title={Specification, Composition, and Placement of Network Services with Flexible Structures}, DOI={<a href=\"https://doi.org/10.1002/nem.1963\">10.1002/nem.1963</a>}, number={2}, journal={International Journal of Network Management}, publisher={Wiley Online Library}, author={Dräxler, Sevil and Karl, Holger}, year={2017}, pages={1--16} }","ama":"Dräxler S, Karl H.

In addition to assigning jobs to processors, the scheduler must distribute the resource among the processors (e.g., for three processors in shares of 20\\%, 15\\%, and 65\\%) and adjust this distribution over time. Each job $j$ comes with a size $p_j \\in \\mathbb{R}$ and a resource requirement $r_j > 0$. Jobs do not benefit when receiving a share larger than $r_j$ of the resource. But providing them with a fraction of the resource requirement causes a linear decrease in the processing efficiency. We seek a (non-preemptive) job and resource assignment minimizing the makespan.Our main result is an efficient approximation algorithm which achieves an approximation ratio of $2 + 1/(m-2)$. It can be improved to an (asymptotic) ratio of $1 + 1/(m-1)$ if all jobs have unit size. Our algorithms also imply new results for a well-known bin packing problem with splittable items and a restricted number of allowed item parts per bin.Based upon the above solution, we also derive an approximation algorithm with similar guarantees for a setting in which we introduce so-called tasks each containing several jobs and where we are interested in the average completion time of tasks (a task is completed when all its jobs are completed).","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1145/3087556.3087578","author":[{"full_name":"Kling, Peter","first_name":"Peter","last_name":"Kling"},{"full_name":"Mäcker, Alexander","first_name":"Alexander","last_name":"Mäcker","id":"13536"},{"full_name":"Riechers, Sören","first_name":"Sören","last_name":"Riechers"},{"full_name":"Skopalik, Alexander","first_name":"Alexander","last_name":"Skopalik","id":"40384"}],"year":"2017","title":"Sharing is Caring: Multiprocessor Scheduling with a Sharable Resource","date_updated":"2022-01-06T07:02:46Z","citation":{"bibtex":"@inproceedings{Kling_Mäcker_Riechers_Skopalik_2017, title={Sharing is Caring: Multiprocessor Scheduling with a Sharable Resource}, DOI={<a href=\"https://doi.org/10.1145/3087556.3087578\">10.1145/3087556.3087578</a>}, booktitle={Proceedings of the 29th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA)}, author={Kling, Peter and Mäcker, Alexander and Riechers, Sören and Skopalik, Alexander}, year={2017}, pages={123--132} }","short":"P.

This paves the way for wide-area service deployments with improved service quality: e.g. user-perceived response times can be reduced by offering services at nearby sites. But always assigning users to the nearest site can be a bad decision if this site is already highly utilised. This paper formalises two related decisions of allocating compute resources at different sites and assigning users to them with the goal of minimising the response times while the total number of resources to be allocated is limited – a non-linear capacitated Facility Location Problem with integrated queuing systems. To efficiently handle its non-linearity, we introduce five linear problem linearisations and adapt the currently best heuristic for a similar scenario to our scenario. All six approaches are compared in experiments for solution quality and solving time. Surprisingly, our best optimisation formulation outperforms the heuristic in both time and quality. Additionally, we evaluate the influence of distributions of available compute resources in the network on the response time: The time was halved for some configurations. The presented formulation techniques for our problem linearisations are applicable to a broader optimisation domain."}],"_id":"64","publisher":"IEEE","page":"121--135","user_id":"477","ddc":["040"],"status":"public","has_accepted_license":"1","citation":{"mla":"Keller, Matthias, and Holger Karl. “Response-Time-Optimised Service Deployment: MILP Formulations of Piece-Wise Linear Functions Approximating Non-Linear Bivariate Mixed-Integer Functions.” <i>IEEE Transactions on Network and Service Management</i>, no. 1, IEEE, 2017, pp. 121--135, doi:<a href=\"https://doi.org/10.1109/TNSM.2016.2611590\">10.1109/TNSM.2016.2611590</a>.","apa":"Keller, M., &#38; Karl, H.
