The integration of heterogeneous resources in the CMS Submission Infrastructure for the LHC Run 3 and beyond
Antonio Perez-Calero Yzquierdo, Marco Mascheroni, Edita Kizinevic +5
While the computing landscape supporting LHC experiments is currently dominated by x86 processors at WLCG sites, this configuration will evolve in the coming years. LHC collaborati…
Adoption of a token-based authentication model for the CMS Submission Infrastructure
Antonio Perez-Calero Yzquierdo, Marco Mascheroni, Edita Kizinevic +6
The CMS Submission Infrastructure (SI) is the main computing resource provisioning system for CMS workloads. A number of HTCondor pools are employed to manage this infrastructure,…
Repurposing of the Run 2 CMS High Level Trigger Infrastructure as a Cloud Resource for Offline Computing
Marco Mascheroni, Antonio Perez-Calero Yzquierdo, Edita Kizinevic +8
The former CMS Run 2 High Level Trigger (HLT) farm is one of the largest contributors to CMS compute resources, providing about 25k job slots for offline computing. This CPU farm w…
HPC resources for CMS offline computing: An integration and scalability challenge for the Submission Infrastructure
Antonio Perez-Calero Yzquierdo, Marco Mascheroni, Edita Kizinevic +5
The computing resource needs of LHC experiments are expected to continue growing significantly during the Run 3 and into the HL-LHC era. The landscape of available resources will a…
