Research interest:

Most of my work has been devoted to the design of practical scheduling and resource allocation algorithms for distributed platforms. In general, most of scheduling problems are NP-Complete in the strong sense, in particular as soon as communications are taken into account or as soon as dependences between tasks are modeled by a general DAG. In this context, the general approach that I proposed is rather to change the problem (i.e. to consider a close problem whose solution is easier) rather than trying to improve the bounds proposed in the literature. To achieve this, the key point is to identify the critical features of the platform/application couple that must be taken into account. For instance, heterogeneity is a key feature for computing resources, and taking contentions into account is crucial for modeling communications. On the other hand, some assumptions are very fruitful in order to cope with the complexity. For instance, assuming that there is a large number of tasks to be processed or a very large message enables to concentrate on steady state and makes many scheduling problems solvable in polynomial time. Along the same ideas, the use of overlay networks makes it possible to design communication schemes restricted to graph classes having good properties.

At the moment, I am interested in

  • understanding the performance of dynamic (randomized) scheduling policies and what level of static knowledge (expressed as affinities) must be taken into account
  • understanding what characteristics of the applications make them efficient to dynamically schedule on heterogeneous resources where performance is hard to predict and failures are likely to happen.
