hwloc 2.0.0 and new memory technologies

TADaaM is releasing the new major hwloc 2.0 version which updates the way we model new memory technologies (HBM, NVDIMM, etc). This is the result of two years of work and several research papers about this new modeling and about improving support for manycore architectures at scale. The announce of hwloc 2.0.0

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 …

Georges Da Costa will present works around “Multi-objective resources optimization: Performance- and Energy-aware  HPC and Clouds“

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 …
