Distributed Authentication in GRID5000 [chapter]

Sebastien Varrette, Sebastien Georget, Johan Montagnat, Jean-Louis Roch, Franck Leprevost
2005 Lecture Notes in Computer Science  
This article expounds and justifies the authentication system used in Grid5000. We first show the limits of classical approaches that are local files and NIS in such configurations.  ...  In this context, authentication is one of the key stone by providing access to the resources. Grid5000 is a french project based on a cluster grid topology.  ...  This system is therefore a particularly good candidate for a robust authentication system in a distributed environment such as Grid5000.  ...

Improving Scalability and Reward of Utility-Driven Self-Healing for Large Dynamic Architectures

Sona Ghahremani, Holger Giese, Thomas Vogel
2020 ACM Transactions on Autonomous and Adaptive Systems  
In addition to formally analyzing the computational effort and optimality of the proposed scheme, we thoroughly demonstrate its scalability and optimality in terms of reward in comparative experiments  ...  They result in scalable solutions but often with merely satisfying adaptation decisions.  ...  The Grid5000 model originates from the Grid5000 system, in which a significant fraction of failures occurs in bursts.  ...
