However, as it is not feasible to realise all types of VNFs in CNs, the coexistence of VMs and CNs is proposed. To put VMs and CNs together, an orchestration framework that can chain services across distributed and heterogeneous domains is required. To this end, we implemented a framework by extending and consolidating state-of-the-art tools and technologies originated from Network Function Virtualization (NFV), Software-defined Networking (SDN) and cloud computing environments. This framework chains services provisioned across Kubernetes and OpenStack domains. During the demo, we deploy a service consist of CN- and VM-based VNFs to demonstrate different features provided by our framework.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_id":"12953","access_level":"closed","file_name":"p240-Kouchaksaraei.pdf","file_size":1206037,"creator":"ups","date_created":"2019-08-26T09:09:50Z","date_updated":"2019-08-26T09:09:50Z"}],"publication":"13th ACM International Conference on Distributed and Event-based Systems","doi":"10.1145/3328905.3332505","conference":{"name":"13th ACM International Conference on Distributed and Event-based Systems","start_date":"2019-06-24","end_date":"2019-06-28","location":"Darmstadt"},"date_updated":"2022-01-06T07:04:21Z","author":[{"full_name":"Razzaghi Kouchaksaraei, Hadi","id":"60845","last_name":"Razzaghi Kouchaksaraei","first_name":"Hadi"},{"first_name":"Holger","full_name":"Karl, Holger","id":"126","last_name":"Karl"}],"place":"Darmstadt","citation":{"mla":"Razzaghi Kouchaksaraei, Hadi, and Holger Karl. “Service Function Chaining Across OpenStack and Kubernetes Domains.” <i>13th ACM International Conference on Distributed and Event-Based Systems</i>, 2019, doi:<a href=\"https://doi.org/10.1145/3328905.3332505\">10.1145/3328905.3332505</a>.","bibtex":"@inproceedings{Razzaghi Kouchaksaraei_Karl_2019, place={Darmstadt}, title={Service Function Chaining Across OpenStack and Kubernetes Domains}, DOI={<a href=\"https://doi.org/10.1145/3328905.3332505\">10.1145/3328905.3332505</a>}, booktitle={13th ACM International Conference on Distributed and Event-based Systems}, author={Razzaghi Kouchaksaraei, Hadi and Karl, Holger}, year={2019} }","short":"H.

Following the steadily growing interest in business model innovation, software tools have shown great potential in supporting business model development and innovation. Yet, understanding the cognitive processes involved in the generation of business model ideas is an aspect of software design-knowledge that has so far been neglected. To investigate whether providing stimuli – in this case, brainstorming questions – can enhance individual creativity in this context, we conduct an exploratory experiment with over 100 participants. Our study is the first to systematically investigate the process of idea generation using a software-based business model development tool with stimuli. Our preliminary findings have the potential to support the future development of business model development tools and to refine the research design used to evaluate such tools."}],"file":[{"file_name":"p547-szopinski(1).pdf","access_level":"closed","file_id":"13899","file_size":1005738,"creator":"dsz","date_created":"2019-10-17T06:58:40Z","date_updated":"2019-10-17T06:58:40Z","relation":"main_file","success":1,"content_type":"application/pdf"}],"status":"public","type":"conference","accept":"1","publication":"Proceedings of the ACM Creativity & Cognition","ddc":["330"],"keyword":["Business model innovation","idea generation","cognitive stimuli","business model development tools","experiment","creativity support system"],"language":[{"iso":"eng"}],"file_date_updated":"2019-10-17T06:58:40Z","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"17","name":"SFB 901 - Subproject C5"}],"_id":"9850","user_id":"36372","department":[{"_id":"276"}]},{"type":"journal_article","accept":"1","status":"public","_id":"9853","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C5","_id":"17"}],"department":[{"_id":"276"}],"user_id":"16205","file_date_updated":"2019-10-17T06:51:18Z","publication_status":"epub_ahead","intvolume":"         7","page":"90-100","citation":{"ieee":"D.

The mechanism has to decide how many units of the item are transferred from the seller to the buyer and how much money is transferred from the buyer to the seller.

Since many scheduling problems are NP-hard in the strong sense, there is only limited research on exact algorithms and how their efficiency scales when implemented on parallel computing architectures. We address this gap by (1) adapting an exact branch-and-price algorithm to a parallel machine scheduling problem on unrelated machines with sequence- and machine-dependent setup times, (2) parallelizing the adapted algorithm by implementing a distributed-memory parallelization with a master/worker approach, and (3) conducting extensive computational experiments using up to 960 MPI processes on a modern high performance computing cluster. With our experiments, we show that the efficiency of our parallelization approach can lead to superlinear speedup but can vary substantially between instances. We further show that the wall time of serial execution can be substantially reduced through our parallelization, in some cases from 94 hours to less than six minutes when our algorithm is executed on 960 processes.","lang":"eng"}],"file":[{"relation":"main_file","content_type":"application/pdf","access_level":"open_access","file_id":"6513","file_name":"cor-parallel-bp-for-upmsp.pdf","file_size":4153528,"date_created":"2019-01-08T14:03:53Z","creator":"hsiemes","date_updated":"2019-01-08T14:03:53Z"}],"status":"public","type":"journal_article","publication":"Computers & Operations Research","ddc":["000"],"keyword":["parallel machine scheduling with setup times","parallel branch-and-price algorithm","high performance computing","master/worker parallelization"],"language":[{"iso":"eng"}],"file_date_updated":"2019-01-08T14:03:53Z","_id":"6512","user_id":"61579","department":[{"_id":"277"}]}]
