Selected recent keynote talks, invited talks and panels


BDEC2 is the second series of BDEC workshops. BDEC2 will focus on the problem that the previous series identified and analyzed, namely, the problem of defining and creating consensus around a shared cyberinfrastructure for science in the data saturated world that is now emerging. Since massive amounts of data will soon be getting generated nearly everywhere, massive amounts of computing and storage will have to be available for use at the “edge” or in the “fog,” as well in commercial Clouds and HPC centers. This is spelled out more detail in a short prospectus. BDEC workshops are closed and invitation-only. BDEC invites representatives of leading application communities to participate in one or more of the workshops and contribute to the BDEC prospective documents.

A comprehensive list of my publications can be found on HAL Open Archives Library:


  • BlobSeer is a data management platform we are currently developing for sharing massive data at very large scales. It originally relies on advanced techniques for decentralized data management and versioning techniques to provide scalable data throughput under heavy data access concurrency.
  • Damaris: Damaris is a middleware for multicore SMP nodes allowing them to efficiently handle data transfers for storage and visualization by dedicating one or a few cores to the application I/O or for in situ visualization. It has been developed within the framework of a collaboration with the Joint Laboratory for Extreme-Scale Computing (JLESC, ex-JLPC). It was successfully evaluated with the CM1 tornado simulation, one of the Blue Waters target applications, on several supercomputers (Titan, Jaguar, Kraken), where it demonstrated excellent scalability.
  • JuxMem: is a platform which illustrates the concept of Grid Data-Sharing Service, defined using a hybrid approach based on Distributed Shared Memory and Peer-to-Peer techniques.
