|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.

|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.
|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 ...

|Malt-related project: Standard documentation workflow and conversion tools for documentation, slides etc||
In order to standardise the way service web sites (both for user facing and administrators pages) are handled across the group and department, IT/CDA proposes a standard way to create, maintain and serve service web sites, based on modern and open technologies (Markdown, Gitlab and Openshift). This is now documented ...
