  1. 168. Coffea-casa: an analysis facility prototype
    Oksana Shadura (University of Nebraska Lincoln (US))

    Long talk

    Data analysis in HEP has often relied on batch systems and event loops; users are given a non-interactive interface to computing resources and consider data event-by-event. The "Coffea-casa" prototype analysis facility is an effort to provide users with alternate mechanisms to access computing resources and enable new programming paradigms. Instead of the command-line interface and...

  2. 46. Evaluating CephFS Performance vs. Cost on High-Density Commodity Disk Servers

    Long talk

    CephFS is a network filesystem built upon the Reliable Autonomic Distributed Object Store (RADOS). At CERN we have demonstrated its reliability and elasticity while operating several 100-to-1000TB clusters which provide NFS-like storage to infrastructure applications and services. At the same time, our lab developed EOS to offer high performance 100PB-scale storage for the LHC at extremely low...

    Long talk

    Generative machine learning models offer a promising way to efficiently amplify classical Monte Carlo generators' statistics for event simulation and generation in particle physics. Given the already high computational cost of simulation and the expected increase in data in the high-precision era of the LHC and at future colliders, such fast surrogate simulators are urgently needed.
