Title: "Data Management and Resilience Techniques at Large Scale"





Abstract:

This talk introduces a series of data management and resilience techniques at large scale. It is structured in three parts. First, it focuses on distributed versioning techniques that keep track of the history of changes for massive data sets, which can be used both to revisit previous states and to optimize concurrent read/write operations. These techniques form the core of the BlobSeer project. Second, it introduces an approach to perform scalable, on-demand broadcast of massive data sets using an adaptive peer-to-peer collaboration strategy, which was adopted by the HPCDS project. Third, it focuses on checkpoint-restart techniques at extreme scale: multi-level checkpointing, adaptive asynchronous post-processing, etc. These techniques form the core of the VeloC project.
