Talk by Amelie Zhou on Jun 15, 2017
Amelie Zhou, postdoc in the Ascola research team will talk about On Achieving Efficient Data Transfer for Graph Processing in Geo-Distributed Datacenters. Graph partitioning, which distributes graph processing workloads to multiple machines for better parallelism, is an important problem for optimizing the performance and communication cost of graph processing jobs. Recently, many graph applications such …

Talk by Valentin Lefèvre on Feb 28, 2017
Valentin Le Fèvre from LIP will present his work. Title: Periodic I/O scheduling for super-computers Abstract: With the ever-growing need of data in HPC applications, the congestion at the I/O level becomes critical in super-computers. Architectural enhancement such as burst-buffers and pre-fetching are added to machines, but are not sufficient to prevent congestion. Recent online …

Jean-Thomas Acquaviva from DataDirect Networks will give a talk about storage in HPC. Titre: IME and Managing the transition to Storage System Hierarchy Abstract: The current storage software stack is the center of a perfect storm. Only five years ago systems were assembled with clearly identified building blocks, each with its own order of magnitude: …

netloc models the entire Curie supercomputer
The TADaaM team succeeded at modeling the entire Curie supercomputing and its interconnection network (one of the largest in Europe, with more than 5000 nodes and 800 switches) thanks to its netloc software. This enables new mapping strategies for thousands of computing tasks in order to improve the performance of numerical simulation applications. Joint work with …

Talk by Juan Luis García Zapata on Sep 27, 2016
Juan Luis García Zapata from the University of Extremadura will present his work on “Spectral graph partition: old and new results” Abstract: A distributed application is modeled as a weighted graph where tasks or processes are the vertices and the edge between two task is weight by the total volume of communications between them. The …

Talk by Guillaume Aupy on Apr 21, 2016
Guillaume Aupy (Vanderbilt Univ.) will give a talk on Optimal Multi-stage algorithm for Adjoint Computation. Abstract: We reexamine the work of Stumm and Walther on multistage algorithms for adjoint computation. We provide an optimal algorithm for this problem whenthere are two levels of check- points, in memory and on disk. Previously, optimal algorithms for adjoint …
