Examples of such applications include distributed file systems and master/slave data replication. We present Flease, an algorithm for decentralized and fault-tolerant lease coordination in distributed systems. Our algorithm allows the processes competing for a resource to coordinate exclusive access through leases among themselves without a central component. The resulting system easily scales with an increasing number of nodes and resources. We prove that Flease ensures exclusive access, i.e. guarantees that there is at most one valid lease at any time.}, language = {en} } @inproceedings{StenderKolbeckHoegqvistetal.2010, author = {Stender, Jan and Kolbeck, Bj{\"o}rn and H{\"o}gqvist, Mikael and Hupfeld, Felix}, title = {BabuDB: Fast and Efficient File System Metadata Storage}, booktitle = {Storage Network Architecture and Parallel I/Os, IEEE International Workshop on}, publisher = {IEEE Computer Society}, address = {Los Alamitos, CA, USA}, doi = {10.1109/SNAPI.2010.14}, pages = {51 -- 58}, year = {2010}, language = {en} } @article{KolbeckHoegqvistStenderetal.2011, author = {Kolbeck, Bj{\"o}rn and H{\"o}gqvist, Mikael and Stender, Jan and Hupfeld, Felix}, title = {Flease - Lease Coordination Without a Lock Server}, volume = {0}, journal = {Parallel and Distributed Processing Symposium, International}, publisher = {IEEE Computer Society}, address = {Los Alamitos, CA, USA}, doi = {10.1109/IPDPS.2011.94}, pages = {978 -- 988}, year = {2011}, language = {en} } @phdthesis{Kolbeck2012, author = {Kolbeck, Bj{\"o}rn}, title = {A fault-tolerant and scalable protocol for replication in distributed file systems}, year = {2012}, language = {en} } @article{SchmidtGoennerGuerlerKolbecketal.2010, author = {Schmidt-Goenner, T. and Guerler, A. and Kolbeck, Bj{\"o}rn and Knapp, E.}, title = {Circular permuted proteins in the universe of protein folds}, volume = {78}, journal = {Proteins}, doi = {10.1002/prot.22678}, pages = {1618 -- 1630}, year = {2010}, language = {en} } @inproceedings{StenderHoegqvistKolbeck2010, author = {Stender, Jan and H{\"o}gqvist, Mikael and Kolbeck, Bj{\"o}rn}, title = {Loosely Time-Synchronized Snapshots in Object-Based File Systems}, booktitle = {Proceedings of the 29th IEEE International Performance, Computing, and Communications Conference}, publisher = {IEEE Computer Society}, doi = {10.1109/PCCC.2010.5682311}, year = {2010}, language = {en} } @article{Kolbeck2009, author = {Kolbeck, Bj{\"o}rn}, title = {A Protocol for Efficient and Fault-tolerant File Replication over Wide-Area Networks}, volume = {0}, journal = {TCPP Ph.D. Forum, Int.
