Integration of the Barcelona Supercomputing Center for CMS computing: Towards large scale production / Acosta-Silva, C (PIC, Bellaterra ; Barcelona, IFAE) ; Peris, A Delgado (Madrid, CIEMAT) ; Molina, J Flix (PIC, Bellaterra ; Madrid, CIEMAT) ; Hernández, J M (Madrid, CIEMAT) ; Yzquierdo, A Pérez-Calero (PIC, Bellaterra ; Madrid, CIEMAT) ; Sánchez, E Pineda (Barcelona, Autonoma U.) ; Domínguez, I Villalonga (Barcelona, Autonoma U.) /CMS Collaboration
The CMS experiment is working to integrate an increasing number of High Performance Computing (HPC) resources into its distributed computing infrastructure. The case of the Barcelona Supercomputing Center (BSC) is particularly challenging as severe network restrictions prevent the use of CMS standard computing solutions. [...]

Computing activities at the Spanish TIER-1 & TIER-2s for the ATLAS Experiment in the LHC Run-3 period and towards High Luminosity / ATLAS Collaboration
The Spanish cloud contributes 4% of ATLAS' computing resources both in terms of TIER-1 and TIER-2 sites. This talk delves into the specific architectures of the different sites contributing to our TIER-1 and federated TIER-2 site whilst also offering a wealth of figures quantifying their performance.

Lightweight site federation for CMS support / Acosta-Silva, C (PIC, Bellaterra ; Barcelona, IFAE) ; Peris, A Delgado (Madrid, CIEMAT) ; Flix, J (PIC, Bellaterra ; Madrid, CIEMAT) ; Guerrero, J M (Madrid, CIEMAT) ; Hernández, J M (Madrid, CIEMAT) ; Yzquierdo, A Pérez-Calero (PIC, Bellaterra ; Madrid, CIEMAT) ; Calonge, F J Rodriguez (Madrid, CIEMAT) ; Gómez-Pulgar, J (Madrid, CIEMAT) /CMS Collaboration
There is a general trend in WLCG towards the federation of resources, aiming for increased simplicity, efficiency, flexibility, and availability. Although general VO-agnostic federation of resources between two independent and autonomous resource centres may prove arduous, a considerable amount of flexibility in resource sharing can be achieved in the context of a single WLCG VO, with a relatively simple approach.

Exploitation of network-segregated CPU resources in CMS / Acosta-Silva, C (BIST, Barcelona ; PIC, Bellaterra) ; Peris, A Delgado (Madrid, CIEMAT) ; Flix, J (PIC, Bellaterra ; Madrid, CIEMAT) ; Frey, J (Wisconsin U., Madison) ; Hernández, J M (Madrid, CIEMAT) ; Pérez-Calero Yzquierdo, A (PIC, Bellaterra ; Madrid, CIEMAT) ; Tannenbaum, T (Wisconsin U., Madison) /CMS Collaboration
CMS is tackling the exploitation of CPU resources at HPC centers where compute nodes do not have network connectivity to the Internet. Pilot agents and payload jobs need to interact with external services from the compute nodes access to the application software (cmvfs) and conditions data (Frontier), management of input and output data files (data management services), and job management (HTCondor).
