Performance optimization in a High Throughput Computing environment

Profiling of computing resources respect to WLCG experiment workloads is a crucial factor to select the most effective resources and to be able to optimise their usage.
There is a rich amount of data collected by the CERN and WLCG monitoring infrastructures just waiting to be turned into useful ...

Cloud data analysis

Cloud synchronization and sharing is a promising area for the preparation of powerful transformative data services. 

The goal of this project is to prepare CERNBOX to be used in connection with heavy-duty activities (large-scale batch processing) on the current LXBATCH infrastructure (LSF) and on its future evolution (HT-Condor): physicists can ...

QA in distributed cloud architecture: evolution of smashbox framework

Cloud synchronization and sharing is an area in evolution with innovative services being built on top of different platforms. CERNBOX is a service ran at CERN to provide at the same time synchronisation services (based on the OwnCloud software) and high-performance data access and sharing (based on EOS, the CERN ...

QA in distributed cloud architecture: injection-fault testing

Clients of the sync&share system (CERNBOX) are particularly exposed to "operational failures" due to heterogeneity of hardware, OS and network environments. 

Sync&share system operates in very heterogenous network environment: from fast, reliable network inside the computing center to unreliable, high-latency ad-hoc connections such as from air-ports etc. 
Windows filesystems ...

Distributed storage systems for big data

The group maintains a framework called dmlite which is used to integrate various types of storage with different protocol frontends. It is the basis of a number of the group’s products such as the Disk Pool Manager (DPM), a grid storage system which holds over 50PB of storage in the ...

Advanced Notifications for WAN Incidents

One of the main challenges in WLCG WAN networking is the network diagnostics and advanced notifications on the issues seen in the network. LHCOPN/LHCONE as the core global networks in WLCG have more than 5000 active links between 120 sites. Currently, most of the issues are only visible by the applications ...

Optimisation of experiment workflows in the Worldwide LHC Computing Grid

The LHC experiments perform the vast majority of the data processing and analysis on the Worldwide LHC Computing Grid (WLCG), which provides a globally distributed infrastructure with more than 500k cores to analyse the tens of PB of data collected each year. Profiling of the computing infrastructure with respect to the ...

Analysis of the I/O performance of LHC computing jobs at the CERN computing centre

The LHC experiments execute a significant fraction of their data reconstruction, simulation and analysis on the CERN computing batch resources. One of the most important features of these data processing jobs is their I/O pattern in accessing the local storage system, EOS, which is based on the xrootd protocol. In ...
