A real-time FPGA-based cluster finding algorithm for LHCb silicon pixel detector / Bassi, Giovanni (INFN, Pisa ; Pisa, Scuola Normale Superiore) ; Giambastiani, Luca (Padua U.) ; Lazzari, Federico (INFN, Pisa ; INFN, Siena ; Siena U.) ; Morello, Michael J (INFN, Pisa ; Pisa, Scuola Normale Superiore) ; Pajero, Tommaso (Oxford U.) ; Punzi, Giovanni (INFN, Pisa ; Pisa U.)
Starting from the next LHC run, the upgraded LHCb High Level Trigger will process events at the full LHC collision rate (averaging 30 MHz). This challenging goal, tackled using a large and heterogeneous computing farm, can be eased addressing lowest-level, more repetitive tasks at the earliest stages of the data acquisition chain. [...]

A novel reconstruction framework for an imaging calorimeter for HL-LHC / Cristella, Leonardo (CERN) /CMS Collaboration
To sustain the harsher conditions of the high-luminosity LHC, the CMS collaboration is designing a novel endcap calorimeter system. The new calorimeter will predominantly use silicon sensors to achieve sufficient radiation tolerance and will maintain highly-granular information in the readout to help mitigate the effects of pileup. [...]

Evaluation of a high-performance storage buffer with 3D XPoint devices for the DUNE data acquisition system / Abed Abud, Adam  (CERN ; Liverpool U.) ; Biery, Kurt (Fermilab) ; Chavez, Carlos (Liverpool U.) ; Ding, Pengfei (Fermilab) ; Flumerfelt, Eric (Fermilab) ; Freeman, John (Fermilab) ; Lehmann Miotto, Giovanna (CERN) ; Roda, Marco (Liverpool U.) ; Rodrigues, Philip (Oxford U.) ; Sipos, Roland (CERN) et al.
The DUNE detector is a neutrino physics experiment that is expected to take data starting from 2028. The data acquisition (DAQ) system of the experiment is designed to sustain several TB/s of incoming data which will be temporarily buffered while being processed by a software based data selection system.

Proximeter CERN’s detecting device for personnel / Merscher, Christoph (CERN) ; Sierra, Rodrigo (CERN) ; Zimmaro, Alessandro (CERN) ; Giordano, Marco (CERN) ; Danzeca, Salvatore (CERN)
he SARS COV 2 virus, the cause of the better known COVID-19 disease, has greatly altered our personal and professional lives. Many people are now expected to work from home but this is not always possible and, in such cases, it is the responsibility of the employer to implement protective measures. [...]

ARCHIVER - Data archiving and preservation for research environments / Devouassoux, Marion (CERN) ; Fernandes, João (CERN) ; Jones, Bob (CERN) ; Lozada, Ignacio Peluaga (CERN) ; Urban, Jakub (CERN)
Over the last decades, several data preservation efforts have been undertaken by the HEP community, as experiments are not repeatable and consequently their data considered unique. ARCHIVER is a European Commission (EC) co-funded Horizon 2020 pre-commercial procurement project procuring R&D; combining multiple ICT technologies including data-intensive scalability, network, service interoperability and business models, in a hybrid cloud environment.

Laurelin: Java-native ROOT I/O for Apache Spark / Melo, Andrew (Vanderbilt U.) ; Shadura, Oksana (Nebraska U.) /CMS Collaboration
Apache Spark[1] is one of the predominant frameworks in the big data space, providing a fully-functional query processing engine, vendor support for hardware accelerators, and performant integrations with scientific computing libraries. One difficulty in adopting conventional big data frameworks to HEP workflows is the lack of support for the ROOT file format in these frameworks. [...]
