Robust Load Delegation in Service Grid Environments
Found in: IEEE Transactions on Parallel and Distributed Systems
By Alexander Fölling, Christian Grimme, Joachim Lepping, Alexander Papaspyrou
Issue Date:September 2010
pp. 1304-1316
In this paper, we address the problem of finding well-performing workload exchange policies for decentralized Computational Grids using an Evolutionary Fuzzy System. To this end, we establish a noninvasive collaboration model on the Grid layer which requir...
Toward an Open Cloud Standard
Found in: IEEE Internet Computing
By Andy Edmonds,Thijs Metsch,Alexander Papaspyrou,Alexis Richardson
Issue Date:July 2012
pp. 15-25
Today's cloud ecosystem features several increasingly divergent management interfaces. Numerous bridging efforts attempt to ameliorate the resulting vendor lock-in for customers. However, as the number of providers continues to grow, the drawback of this a...
A Restful Approach to Service Level Agreements for Cloud Environments
Found in: Dependable, Autonomic and Secure Computing, IEEE International Symposium on
By Florian Blümel,Thijs Metsch,Alexander Papaspyrou
Issue Date:December 2011
pp. 650-657
Cloud Computing is becoming more and more a commodity service to all kinds of businesses. This leads to a stronger need for dependable service guarantees on the resources or applications offered to the customer by the provider via Service Level Agreements....
Applying P2P Strategies to Scheduling in Decentralized Grid Computing Infrastructures
Found in: Parallel Processing Workshops, International Conference on
By Christian Grimme, Joachim Lepping, Jonathan Moreno Picon, Alexander Papaspyrou
Issue Date:September 2010
pp. 295-302
In this paper, we propose a new algorithm for job interchange in Computational Grids that consist of autonomous and equitable HPC sites, called Shaking-G. Originally developed for balancing the sharing of video files in P2P networks, we conceptually transf...
Benefits of Job Exchange between Autonomous Sites in Decentralized Computational Grids
Found in: Cluster Computing and the Grid, IEEE International Symposium on
By Christian Grimme, Joachim Lepping, Alexander Papaspyrou
Issue Date:May 2008
pp. 25-32
This paper examines the job exchange between parallel compute sites in a??decentralized Grid scenario. Here,the local scheduling system remains untouched and continues normal operation. In order to establish the collaboration and interaction between sites ...
Discovering performance bounds for grid scheduling by using evolutionary multiobjective optimization
Found in: Proceedings of the 10th annual conference on Genetic and evolutionary computation (GECCO '08)
By Alexander Papaspyrou, Christian Grimme, Joachim Lepping
Issue Date:July 2008
pp. 227-269
In this paper, we introduce a methodology for the approximation of optimal solutions for a resource allocation problem in the domain of Grid scheduling on High Performance Computing systems. In detail, we review a real-world scenario with decentralized, eq...
