General description of the EOS service @CERN
The ALICE detector and data acquisition system was substantially upgraded for Run3 and beyond. One of the main elements of the upgrade was the O2 processing cluster, which compresses the detector data in real time. The output of the compression is then written to EOS buffer for subsequent asynchronous data processing and archival. The requirements for the EOS storage are substantial: 120GB/sec...
This is going to be a brief presentation regarding the operation status of Custodial Disk Storage (CDS) system provided for the ALICE experiment as a Tape. The CDS system is basically using EOS with its erasure coding implementation (RAIN) for the data protection. The CDS joined the WLCG Tape Challenges in the previous year and about a PB of data has been transferred from the experiment. A...
In this communication, we are going to present the deployment project of the EOS storage software solution at the GRIF site. GRIF is a distributed site made of four (4) different subsites, in different locations of the Paris region. The worst network latency between the subsites is within 2-4 msec with 3 of them connected with a 100G connection. The objective is to consolidate the four (4)...
The Joint Research Centre (JRC) of the European Commission is running the Big Data Analytics Platform (BDAP) to enable the JRC projects to process and analyze a wide range of data, providing knowledge and insights in support of EU policy making.
EOS is the main storage system of the BDAP for scientific data. It is in use at JRC since 2016. The gross capacity of 20 PB is currently in the...
This is a talk introducing the GroupBalancer and what it does. We also cover about the current in place GroupBalancer improvements introduced from 4.8.78 release, the ways to configure this for deployments, some figures from existing deployements and what the roadmap for the future holds with these functionalities.
Migrating the AMS experiment data from EOSPUBLIC to EOSAMS02 stimulated development of tools which might be useful in general for similar exercises in the future. We will show the work in progress.
Report on the latest tests done at SLAC with the native XRootD EC library.
Physics analysis is done at CERN in several different ways, using both interactive and batch resources and EOS for data storage. In order to understand if and how the CERN computer centre should change the way analysis is supported for Run3, we performed several performance studies on two fronts: measuring the performance and utilisation levels of EOS with respect to the current analysis...
This presentation will introduce the roadmap for EOS5 during the Run-3 period.
