The Joint Research Centre (JRC) of the European Commission has set up the Big Data Analytics Platform to enable the JRC projects to process and analyse big data, extracting knowledge and insights in support of EU policy making.
Since 2016, EOS is the main storage component of the platform. In 2020, the total gross capacity of this instance has reached 19 PiB.
The Big Data Analytics...

Our team is in charge of providing storage and transfer services for the LHC and non-LHC experiments at CERN. In this presentation we are going to walk you through the activities of the EOS operations team at CERN in 2020. We are going to focus on the achievements, hurdles and lessons learned throughout the past year.

Mr Dan Szkola (Fermi National Accelerator Lab. (US))01/03/2021, 15:40
Fermilab has been running an EOS instance since testing began in June 2012. By May 2013, before becoming production storage, there was 600TB allocated for EOS. Today, there is approximately 11PB of storage available in the EOS instance.
An update of our current experiences and challenges running an EOS instance for use by the Fermilab LHC Physics Center (LPC) computing cluster. The LPC...

The institutes at the Vienna Biocenter (GMI, IMBA, IMP) have run HPC services for their life sciences research for several years. With our new infrastructure "CLIP", additional partners came on board in 2019, including the Austrian high-energy physics community.
Beginning in 2020 the Austrian grid T2 setup was modernized and based on the CLIP infrastructure.
We run a converged EOS...

We present a disk-based custodial storage for the ALICE experiment at CERN to preserve its raw data alternative to tape with the EOS QRAIN. In this presentation, we describe the detailed system deployment of disk-based custodial storage, the integration to the ALICE experiment and the current status of system monitoring such as hardware error detection and power consumption measurement.

Haibo li (Institute of High Energy Physics Chinese Academy of Science)02/03/2021, 08:35
In this presentation, we will report our current experiences and challenges with running EOS instances for used by IHEP CAS. Currently, IHEP has a total of 42PB storage, of which EOS accounts for 16PB, an increase of 10PB in 2020. At present, the LHAASO experiment mainly uses EOS as its mass storage system. In addition, the JUNO experiment has completed the construction of EOS testbed, and EOS...

Particle physics computing model has a kind of high statistical calculation, such applications need to access a large amount of data for analysis, the data I/O capability is very high requirements.For example, the LHAASO experiment generates trillions of events each year, and the large raw data needs to be decode to encode and mark before it can be analyzed. In this process, very high I/O...

Mr Andrey Kirianov (NRC Kurchatov Institute PNPI (RU))02/03/2021, 10:55
In this talk we will share our experience in implementing write buffering with background stage-out of files from a site accessing the Data Lake prototype using EOS built-in LRU and File Converter engines. This study was aimed at improving resource usage for CPU-only sites by reducing the data stage-out overhead.
