The I3S LABORATORY

It's on the SophiaTech campus in the heart of the Sophia Antipolis technology park our laboratory conducts research in the field of information science and communication.
"Advancing knowledge, consider the economic and technological realities, while imagining tomorrow's solutions."

The I3S laboratory is one of the largest information and communication science laboratories in the French Riviera. it was one of first ones to settle down on Sophia Antipolis Science and Technology Park. It consists of a little less than 300 people. [+...]

In partnership with CNRS and INRIA, and numerous industrial collaborations, we work on the themes of innovative research at the cutting edge of science and technology: systems and networks ubiquitous, biology and digital health, modeling for environment interactions and practices. [+...]

 

The laboratory is organized in 4 teams:

COMRED team (French acronym for Communications, Networks, Embedded Systems, Distributed Systems)
MDSC team (French acronym for Discrete Models for Complex System)
SIS team (Signal, Image and Systems)
SPARKS team (Scalable and Pervasive softwARe and Knowledge Systems)

FOCUS DU MOIS

Alessio Pagliari, Fabrice Huet, Guillaume Urvoy-Keller. On the Cost of Acking in Data Stream Processing Systems. 2019 19th IEEE/ACM International Symposium on Cluster, Cloud, and Grid Computing (CCGRID)

Data Stream Processing, Message Reliability, Apache Storm, Acking Framework, Scheduling

The widespread use of social networks and applications such as IoT networks generates a continuous stream of data that companies and researchers want to process, ideally in real-time. Data stream processing systems (DSP) enable such continuous data analysis by implementing the set of operations to be performed on the stream as directed acyclic graph (DAG) of tasks. While these DSP systems embed mechanisms to ensure fault tolerance and message reliability, only few studies focus on the impact of these mechanisms on the performance of applications at runtime. In this paper, the authors demonstrate the impact of the message reliability mechanism on the performance of the application. They use an experimental approach, using the Storm middleware, to study an acknowledgment-based framework. They compare the two standard schedulers available in Storm with applications of various degrees of parallelism, over single and multi cluster scenarios. The authors show that the acking layer may create an unforeseen bottleneck due to the acking tasks placement; a problem which, to the best of their knowledge, has been overlooked in the scientific and technical literature. The authors propose two strategies for improving the acking tasks placement and demonstrate their benefit in terms of throughput and latency.
