CMS Tier-0 data processing during the detector commissioning in Run-3
/ Amado Valderrama, Jhonatan Andres (Nebraska U.) ; Eysermans, Jan (MIT) ; Giraldo Villa, German Felipe (CERN) ; Hufnagel, Dirk (Fermilab) ; Kovalskyi, Dmytro (MIT) ; Linares Sancho, Antonio (Wisconsin U., Madison)
/CMS Collaboration
The CMS Tier-0 system is responsible for the prompt processing and distribution of the data collected by the CMS Experiment. A number of upgrades were implemented during the long shutdown 2 of the Large Hadron Collider, which improved the performance and reliability of the system. [...]

HPC resource integration into CMS Computing via HEPCloud
/ Hufnagel, Dirk (Fermilab) ; Holzman, Burt (Fermilab) ; Mason, David (Fermilab) ; Mhashilkar, Parag (Fermilab) ; Timm, Steven (Fermilab) ; Tiradani, Anthony (Fermilab) ; Khan, Farrukh Aftab (Fermilab) ; Gutsche, Oliver (Fermilab) ; Bloom, Kenneth (U. Nebraska, Lincoln)
The higher energy and luminosity from the LHC in Run 2 have put increased pressure on CMS computing resources. Extrapolating to even higher luminosities (and thus higher event complexities and trigger rates) beyond Run3, it becomes clear that simply scaling up the the current model of CMS computing alone will become economically unfeasible. [...]

HEPCloud, a New Paradigm for HEP Facilities: CMS Amazon Web Services Investigation
/ Holzman, Burt (Fermilab) ; Bauerdick, Lothar A.T. (Fermilab) ; Bockelman, Brian (Nebraska U.) ; Dykstra, Dave (Fermilab) ; Fisk, Ian (New York U.) ; Fuess, Stuart (Fermilab) ; Garzoglio, Gabriele (Fermilab) ; Girone, Maria (CERN) ; Gutsche, Oliver (Fermilab) ; Hufnagel, Dirk (Fermilab) et al.
Historically, high energy physics computing has been performed on large purpose-built computing systems. These began as single-site compute facilities, but have evolved into the distributed computing grids used today. [...]

The Diverse use of Clouds by CMS
/ Andronis, Anastasios (Ioannina U. ; CERN) ; Bauer, Daniela (Imperial Coll., London) ; Chaze, Olivier (CERN) ; Colling, David (Imperial Coll., London) ; Dobson, Marc (CERN) ; Fayer, Simon (Imperial Coll., London) ; Girone, Maria (CERN) ; Grandi, Claudio (INFN, Bologna) ; Huffman, Adam (Imperial Coll., London) ; Hufnagel, Dirk (Fermilab) et al.
The resources CMS is using are increasingly being offered as clouds. In Run 2 of the LHC the majority of CMS CERN resources, both in Meyrin and at the Wigner Computing Centre, will be presented as cloud resources on which CMS will have to build its own infrastructure. [...]

/CMS
CMS is using a tiered setup of dedicated computing resources provided by sites distributed over the world and organized in WLCG. These sites pledge resources to CMS and are preparing them especially for CMS to run the experiment's applications. [...]
