Participant : Olivier Glück.

Olivier Glück has been invited professor by Concordia University (Faculty of Engineering & Computer Science, Department of Computer Science & Software Engineering). He has conducted researches with Dr. Brigitte Jaumard, Professor & Research Chair, Tier 1, on the Optimization of Communication Networks. He has worked on the following Virtual Machine (VM) migration optimization problem: find a scheduling of VM migration that minimizes the makespan i.e., total duration of the migration assuming that the current VM placement and the target one are given. He has proposed a new sequence-based optimization model with a Mixed Integer Linear Program (MILP), which not only guarantees the finding of the best VM migration scheduling but also the migration of the largest possible number of VMs in the case of deadlocks. He also worked on the design of heuristic algorithms for VM migration and a generator of real VM migration instances to evaluate the models and heuristics proposed. He has also worked on the task offloading problem in edge computing.
