In this contribution we report on the ongoing R&D activity aiming at preparing the EOS ALICE O2 storage cluster for the very demanding requirements of Run 3. After the planned upgrades of LHC and ALICE detectors, the ALICE experiment is expected to increase the data-taking rate handled by the online system and then recorded into permanent storage by one order of magnitude. In order to...
Distributed computing involves processing data from far remote site. We
explore a new type of cache, XCache, developed within XROOTD, and
explore the its capability to improve the access of the jobs to remote
storages. The proof-of-concept is realized within the ESCAPE european
project and measurement of the performances are done using remote sites.
The presentation will develop the...
The Cern VM File System (CVMFS) is a service for fast and reliable software distribution on a global scale. It is capable of delivering scientific software onto physical nodes, virtual machines, and HPC clusters by providing POSIX read-only file system access. Files and metadata are downloaded on-demand by means of HTTP requests and take advantage of aggressive caching on intermediate caches...
The File Transfer Service (FTS) is a fundamental component for the LHC experiments, distributing the majority of the LHC data across the WLCG infrastructure. Tightly integrated with experiment frameworks, it has transferred more than 1 billion files and a total of 950 petabytes of data in 2019 alone. With more than 30 experiments using FTS at CERN and outside, it has steadily gained popularity...
The German Helmholtz Association (HGF) encompasses 19 research institutes distributed all over Germany, covering a wide variety of research topics ranging from particle and material physics over cancer research to marine biology. In order to stimulate collaborations between different centres, the HGF established so-called incubator platforms. Two of those platforms, relevant for this...
