Abstract
The era of Exascale computing raises new challenges for HPC. Intrinsic characteristics of those extreme scale platforms bring energy and reliability issues. To cope with those constraints, applications will have to be more flexible in order to deal with platform geometry evolutions and unavoidable failures. Thus, to prepare for this upcoming era, a strong effort must be made on improving the HPC software stack. This work focuses on improving the study of a central part of the software stack, the HPC runtimes. To this end we propose a set of extensions to the Distem emulator that enable the evaluation of fault tolerance and load balancing mechanisms in such runtimes. Extensive experimentation showing the benefits of our approach has been performed with three HPC runtimes: Charm++, MPICH, and OpenMPI.

Intrinsic characteristics of those extreme scale platforms bring energy and reliability issues. To cope with those constraints, applications will have to be more flexible in order to deal with platform geometry evolutions and unavoidable failures. Thus, to prepare for this upcoming era, a strong effort must be made on improving the HPC software stack. This work focuses on improving the study of a central part of the software stack, the HPC runtimes. To this end we propose a set of extensions to the Distem emulator that enable the evaluation of fault tolerance and load balancing mechanisms in such runtimes. Extensive experimentation showing the benefits of our approach has been performed with three HPC runtimes: Charm++, MPICH, and OpenMPI.</div></front></TEI><affiliations><list><country><li>France</li></country><region><li>Grand Est</li><li>Lorraine (région)</li></region><settlement><li>Metz</li><li>Nancy</li></settlement><orgName><li>Université de Lorraine</li></orgName></list><tree><country name="France"><region name="Grand Est"><name sortKey="Ruiz, Cristian" sort="Ruiz, Cristian" uniqKey="Ruiz C" first="Cristian" last="Ruiz">Cristian Ruiz</name></region><name sortKey="Emeras, Joseph" sort="Emeras, Joseph" uniqKey="Emeras J" first="Joseph" last="Emeras">Joseph Emeras</name><name sortKey="Jeanvoine, Emmanuel" sort="Jeanvoine, Emmanuel" uniqKey="Jeanvoine E" first="Emmanuel" last="Jeanvoine">Emmanuel Jeanvoine</name><name sortKey="Nussbaum, Lucas" sort="Nussbaum, Lucas" uniqKey="Nussbaum L" first="Lucas" last="Nussbaum">Lucas Nussbaum</name></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
