/CMS
The connection of diverse and sometimes non-Grid enabled resource types to the CMS Global Pool, which is based on HTCondor and glideinWMS, has been a major goal of CMS. These resources range in type from a high-availability, low latency facility at CERN for urgent calibration studies, called the CAF, to a local user facility at the Fermilab LPC, allocation-based computing resources at NERSC and SDSC, opportunistic resources provided through the Open Science Grid, commercial clouds, and others, as well as access to opportunistic cycles on the CMS High Level Trigger farm.

Stability and scalability of the CMS Global Pool: Pushing HTCondor and glideinWMS to new limits

The CMS Global Pool, based on HTCondor and glideinWMS, is the main computing resource provisioning system for all CMS workflows, including analysis, Monte Carlo production, and detector data reprocessing activities. The total resources at Tier-1 and Tier-2 grid sites pledged to CMS exceed 100,000 CPU cores, while another 50,000 to 100,000 CPU cores are available opportunistically, pushing the needs of the Global Pool to higher scales each year.

Using the GlideinWMS System as a Common Resource Provisioning Layer in CMS

CMS will require access to more than 125k processor cores for the beginning of Run 2 in 2015 to carry out its ambitious physics program with more and higher complexity events. During Run1 these resources were predominantly provided by a mix of grid sites and local batch resources. [...]

Pushing HTCondor and glideinWMS to 200K+ Jobs in a Global Pool for CMS before Run 2
/ Balcas, J (Vilnius U.) ; Belforte, S (INFN, Trieste ; Trieste U.) ; Bockelman, B (Nebraska U.) ; Gutsche, O (Fermilab) ; Khan, F (Quaid-i-Azam U.) ; Larson, K (Fermilab) ; Letts, J (UC, San Diego) ; Mascheroni, M (INFN, Milan Bicocca ; Milan Bicocca U.) ; Mason, D (Fermilab) ; McCrea, A (UC, San Diego) et al.
The CMS experiment at the LHC relies on HTCondor and glideinWMS as its primary batch and pilot-based Grid provisioning system. So far we have been running several independent resource pools, but we are working on unifying them all to reduce the operational load and more effectively share resources between various activities in CMS.

CMS experience of running glideinWMS in High Availability mode
/ Sfiligoi, Igor (UC, San Diego) ; Letts, James (UC, San Diego) ; Belforte, Stefano (INFN, Trieste) ; Mc Crea, Alison Jean (UC, San Diego) ; Larson, Krista Elaine (Fermilab) ; Zvada, Marian (Karlsruhe U., EKP) ; Holzman, Burt (Fermilab) ; PÂ Mhashilkar ; Bradley, Daniel Charles (Wisconsin U., Madison) ; Saiz Santos, Maria Dolores (UC, San Diego) et al.
The CMS experiment at the Large Hadron Collider is relying on the HTCondor-based glideinWMS batch system to handle most of its distributed computing needs. In order to minimize the risk of disruptions due to software and hardware problems, and also to simplify the maintenance procedures, CMS has set up its glideinWMS instance to use most of the attainable High Availability (HA) features.
