Présentation
Patricia Stolf is a Professor in Computer Science at the University of Toulouse. She received her PhD from INSA (Toulouse, France), in 2004. She is a member of the IRIT Laboratory. Her main interests are related to large scale distributed systems like grid or clouds, distributed algorithms and autonomic computing.
She is currently working on PEPR Cloud (CareCloud), PEPR TASE (AI-NRGY) and IPCEI CIS Next Generation Cloud Infrastructure and Services (E2CC project). The main topics are energy efficiency and sufficiency in cloud and in the continuum edge-cloud.
She has been involved in different research projects: in the ACTION COST IC0804 Energy Efficiency in Large Scale Distributed Systems, in the European CoolEmAll project, in the national ANR SOP project and in the national ANR Datazero project.
She has worked on the ANR Datazero2 project studying how to manage the electricity and IT services in a datacenter operated with several green energy sources.
She has lead the ANR i-Nondations (e-Flooding) project which aims to handle fast floods in crisis management and resiliency. The project suggests managing three phases: before, during, and after a crisis in a loop of feedback coming from the autonomic field called MAPE-K loop. It is based on four steps : Monitoring, Analysis, Planning and Execution with a Knowledge database. The monitoring will detect events, Analysis will analyze the risks based on models of predictions; creation of metrics to measure the impact on infrastructures; and proposing functions to evaluate alternative trajectories. The Plan will decide how to handle the crisis in order to find the optimal on the alternatives and then actions will be executed. Two loops will be used : one for short term timescale and one for long term. The short term one will aim to handle the crisis while the long term one will aim to prevent other crisis. Both loops will interact through a learning process. The Execute module of the loops will not be addressed in this project.
Her expertise covers resources management (multi-objectives optimization problems) and autonomic computing in different contexts: cloud computing (load-balancing, energy aware and thermal aware placement) and crisis management.
