About the research centre or Inria department

The Inria Lille - Nord Europe research centre, created in 2008, has a staff of 360, including 305 scientists in 15 research teams. Recognised for its strong involvement in the socio-economic development of the Hauts-De-France region, the Inria Lille - Nord Europe research centre pursues a close relationship with large companies and SMEs. By promoting synergies between researchers and industrialists, Inria participates in the transfer of skills and expertise in digital technologies and provides access to the best European and international research for the benefit of innovation and companies, particularly in the region.


For more than 10 years, the Inria Lille - Nord Europe centre has been located at the heart of Lille's university and scientific ecosystem, as well as at the heart of Frenchtech, with a technology showroom based on Avenue de Bretagne in Lille, on the EuraTechnologies site of economic excellence dedicated to information and communication technologies (ICT).

Context

The PULSE challenge, shared by Inria and Qarnot computing, aims to develop and promote best practices in geo-distributed hardware and software infrastructures for intensive computing with a reduced environmental footprint.

The aim of this postdoc is to better quantify the difference in environmental footprint of different models of geo-distributed computing, so as to be able to better manage the induced impacts (according to a multi-criteria approach). Ultimately, we hope to be able to recommend best practice hardware and software architectures to drastically reduce impacts while offering the best quality of service to end-users.

Assignment

This project aims to develop two models to compare the environmental impact of a centralised and a decentralised computing service.

The two models should be based on the same assumptions and follow methodologies that are as close as possible in order to achieve directly comparable results.

The project will not be limited to modelling the operational carbon footprint of the service, but will also include :

  • all peripheral services requested by the calculation, i.e. storage and network services, etc.
  • all the peripheral infrastructures concerned by the calculation, i.e. the land of the data centre, data transport, etc.
  • the analysis of the life cycle of the system,
  • the entire environmental footprint: in addition to carbon and greenhouse gas emissions, the impact on rare metals, on water, on soil pollution, etc.
  • more qualitative data to develop a case for the most virtuous model

Main activities

The researcher will have to understand these different subjects through a consequent bibliographical research. The researcher will then have to work on the modelling of each of these paradigms using the most suitable tools. It will be potentially desirable to propose several qualities of models, for example an advanced model and a simpler model. In all cases, it will be essential to produce a model that is easy to use and modify, a priori in the form of an Excel file.

In addition, it will be necessary to develop a more qualitative argument for the most virtuous model.
