Journal ArticleDOI
Consistent checkpointing for transaction systems
TL;DR: This paper answers the question of can these data checkpoints be members of a same consistent global checkpoint by providing a necessary and suucient condition suited to transaction systems and two non-intrusive data checkpointing protocols are designed from this condition.
Book ChapterDOI
Integrated monitoring of infrastructures and applications in cloud environments

TL;DR: This article presents the approach that has been taken while designing and implementing the monitoring sub-system for the Cloud-TM FP7 project, which is aimed at realizing a self-adapting, Cloud based middleware platform providing transactional data access to generic customer applications.
Proceedings ArticleDOI
A Lock-Free O(1) Event Pool and its Application to Share-Everything PDES Platforms
TL;DR: This article presents a lock-free event pool which also provides amortized O(1) time complexity for both insertions and extractions, and can sustain highly concurrent accesses, while not leading to noticeable performance degradation when scaling up the thread count.
Proceedings ArticleDOI
Fast-software-checkpointing in optimistic simulation: embedding state saving into the event routine instructions
TL;DR: The obtained data show that FSC, combined with a sparse state saving strategy may represent the best checkpointing solution in case of both medium/small state granularity simulations and large stategranularity simulations even with small (but non-minimal) portions of the state updated by event execution.
Book ChapterDOI
Checkpointing protocols in distributed systems with mobile hosts: A performance analysis
TL;DR: The basic characteristics a checkpointing protocol needs to work with mobile hosts are shown, namely, reduction of the number of checkpoints, the use of incremental checkpointing and consistent global checkpoint built on the fly.
