National Initiatives

• Project Acronym: OverFlow.

• Project Title: Workflow Data Management as a Service for Multisite Applications.

• Coordinator: Alexandru Costan.

• Duration: Octobre 2015–October 2019.

• Other Partners: None (Young Researcher Project).

• External collaborators: Kate Keahey (University of Chicago and Argonne National Laboratory), Bogdan Nicolae (Huawei Research) and Christophe Blanchet (Institut Français de Bioinformatique).

• Abstract: This JCJC project led by Alexandru Costan investigates approaches to data management enabling an efficient execution of geographically distributed workflows running on multi-site clouds.

• Progress: In 2017, we have reviewed in depth the technical and architectural needs of data storage for the use cases that drive OverFlow, in order to consolidate a set of requirements for its future architecture. Based on these workflow traces, in a second step, we have investigated the suitable benchmarks that reasonably represent them. In this direction, we have first focused on ingestion and storage optimisations for such complex deployments, in particular the novel support for concurrent writes. The project was successfully reviewed at T0+18.

• Project Acronym: KerStream.

• Project Title: Big Data Processing: Beyond Hadoop!

• Coordinator: Shadi Ibrahim .

• Duration: January 2017–January 2021.

• Other Partners: None (Young Researcher Project).

• Abstract: This JCJC project led by Shadi Ibrahim aims to address the limitations of Hadoop when running stream Big Data applications on large-scale clouds and to do a step beyond Hadoop by proposing a new approach, called KerStream, for scalable and resilient stream Big Data processing on clouds. The KerStream project can be seen as the first step towards developing the first French middleware that handles Stream Data processing at Scale.

• Note: Shadi Ibrahim left the KerData team in April 2017, so that this contract is no longer managed within the KerData team.

• Project Acronym: ADT Damaris

• Project Title: Technology development action for te Damaris environment.

• Coordinator: Alexandru Costan.

• Duration: 2016–2018.

• Abstract: This action aims to support the development of the Damaris software. Inria's Technological Development Office (D2T, Direction du Développement Technologique) provided 2 years of funding support for a senior engineer.

  Hadi Salimi is funded through this project to document, test and extend the Damaris software and make it a safely distributable product.
