CMS Outer Tracker Module Production and Integration at NISER / Rahul Kumar Agrawal
In the LHC long shutdown 3, due to start in mid-2026, the LHC will be upgraded to the High-Luminosity LHC. To address the challenges for operation at the HL-LHC, such as an increased interaction rate and higher radiation levels, an upgrade of the tracking system of the CMS detector is being built. [...]

Commissioning and exploitation of the MareNostrum5 cluster at the Barcelona Supercomputing Center for CMS computing / Delgado Peris, Antonio (Madrid, CIEMAT) ; Flix Molina, Jose (Madrid, CIEMAT) ; Hernandez, Jonathan Matthew (UC, San Diego) ; Perez-Calero Yzquierdo, Antonio Maria (Madrid, CIEMAT) /CMS Collaboration
The MareNostrum 5 (MN5) is the newly deployed pre-exascale EuroHPC supercomputer hosted at the Barcelona Supercomputing Center (BSC) in Spain. Its 750,000-core general-purpose CPU cluster offers new opportunities for CMS data processing and simulation but also presents integration challenges within the CMS distributed computing system, particularly due to network segregation for compute nodes.
