CINTIA: A distributed, low-latency index for big interval data

Ruslan Mavlyutov, Philippe Cudre-Mauroux
2015 2015 IEEE International Conference on Big Data (Big Data)  
We also propose a lowlatency, Big Data system that implements CINTIA on top of a popular distributed file system and efficiently manages large interval data on clusters of commodity machines.  ...  In this paper we introduce CINTIA-the Checkpoint INTerval Index Array-an efficient data structure to store and query interval data, which achieves high memory locality and outperforms state-of-the art  ...  The value of the checkpoint step ChS has a strong influence both on the efficiency of our structures and on its memory consumption.  ...

Phosphorylation of serine 1387 in Brca1 is specifically required for the Atm-mediated S-phase checkpoint after ionizing irradiation

Bo Xu, Anne H O'Donnell, Seong-Tae Kim, Michael B Kastan
2002 Cancer Research  
It is clear that one of the roles of the Brca1 protein is to facilitate cellular responses to DNA damage.  ...  We also found that mutation of serine 1423 in Brca1, a target of Atm phosphorylation, abrogates the G2-M checkpoint but not the ionizing irradiation-induced S-phase checkpoint.  ...  Acknowledgments We gratefully acknowledge the technical assistance of Diane Woods and Margaret Reis.  ...

Quasi-synchronous checkpointing: Models, characterization, and classification

D. Manivannan, M. Singhal
1999 IEEE Transactions on Parallel and Distributed Systems  
Asynchronous checkpointing provides maximum autonomy for processes to take checkpoints; however, some of the checkpoints taken may not lie on any consistent global checkpoint, thus making the checkpointing  ...  In synchronous checkpointing, processes synchronize their checkpointing activities so that a globally consistent set of checkpoints is always maintained in the system.  ...  ACKNOWLEDGMENTS The authors thank the anonymous referees for their excellent suggestions for improvement of the paper.  ...
