TADaaM (Topology Aware DAtA Management) is a new Inria project team targeting the optimization of HPC applications taking into account the topology, the affinity, the memory hierarchy, the network contention, the input data and other factors impacting performance. In this talk, we will give an overview of the problematic we want to address, examples of concrete research issues we are looking at as well as set of existing software and results that will be the basis of this project for the coming years. This talk will welcome comments and feedback about this project as well as collaborations and use cases.

Biography: Emmanuel Jeannot is a senior research scientist at INRIA (Institut National de Recherche en Informatique et en Automatique) and he has been conducting his research at INRIA Bordeaux Sud-Ouest and at the LaBRI laboratory since 2009. Before that, he held the same position at INRIA Nancy Grand-Est. In 2006 he was a visiting researcher at the University of Tennessee, ICL laboratory. From 2000 to 2005, he was assistant professor at the Université Henry Poincaré in Nancy. During the period 2000–2009, he did research at the LORIA laboratory. He got his Master and PhD degrees in computer science in 1996 and 1999, respectively both from Ecole Normale Supérieure de Lyon, at the LIP laboratory. After his PhD, he spent one year as a postdoc at the LaBRI laboratory in Bordeaux. His main research interests are algorithms and models for parallel machines, scheduling for heterogeneous environments, data redistribution, distributed computing software, adaptive online compression and programming models.
