15- Design and study of green aspects in parallel resources simulation for
scheduling in distributed platforms - GRAAL
Type de poste : Post-doctorant
Lieu de travail : Lyon
Thème de recherche : Algorithmique, programmation, logiciels et architectures
Projet : GRAAL


Environment

Yves Caniou - yves.caniou@ens-lyon.fr

Research team name: GRAAL

Research domain: Networks, Systems and Services, Distributed Computing

Research theme: Algorithms and Scheduling for Distributed Heterogeneous
Platforms

This position is offered at the "Rhone-Alpes" Research Unit of INRIA, located
near Grenoble and Lyon.
The Unit includes more than 700 people, within 34 research teams and 10
support services.

Deadline for applications: 21/03/2010.
Monthly salary after taxes : 2127.64 € (medical insurance included)

Note: recommendation letters can be sent separetely from the application file,
to: recrutpostdoc@inrialpes.fr

Activities
Context:
Financial cost and carbon footprint are central to research issues concerning
High Performance Computing and its network aspects. Hence last technologies
bring for example processors able to vary their frequency speed in order to
consume less power directly (at processor level) and indirectly (at the air
conditioning level of a machines room for example).
On another level, researches are leaded to develop batch reservation systems
able to dynamically turn on and off resources, and dynamically reduce their
speed, in function of the load of the parallel machine they manage.
In parallel, studies on scheduling in distributed systems require simulation
tools implementing models the closest to reality in order to replay
experiences in the same conditions to confront approaches, analyze behaviors
and compare results that we cannot study and/or quantify in purely
theoretical.

State of Art:
Simgrid is a distributed platform simulator implementing several layers and
models for simulation (processors and network). With the module Simbatch, we
have extended the functionalities of Simgrid, making possible to simulate
parallel resources and their batch manager for study of cluster scheduling
issues as well as distributed scheduling issues at Grid level.
In parallel, carbon footprint measures have been taken on the Grid'5000 site
of Lyon by a research team of Lyon. Models are also studied, both on the
consumption of a on/off status change of a machine (stop, hibernate, etc.)
and on frequency modulation by teams in Lyon and Toulouse, in order to
integrate such mechanisms in OAR, the batch manager developed in Grenoble,
which is deployed on each site of Grid'5000.

Subject:
The main objective of this work is to study, adapt and implement energy
consumption models in the parallel resources simulator Simbatch.
Scheduling and re-scheduling based on green metrics, which follow actual work
in progress in the team, will be conducted and used to validate the
simulator.

Skills and profile
The candidate is expected to have knowledge on distributed platforms,
computing Grid and on scheduling in heterogeneous distributed platforms.
Candidates with experiences in Simgrid and Simbatch will be favored.
