Near-infrared radiation induced attenuation in nested anti-resonant nodeless fibers
/ Medaer, Sacha E R (CERN ; Erlangen - Nuremberg U., Theorie III) ; Bradley, Thomas D (Eindhoven, Tech. U.) ; Di Francesca, Diego (CERN) ; Fu, Qiang (Southampton U.) ; Jasion, Gregory (Southampton U.) ; Kuhnhenn, Jochen (Fraunhofer Inst., Euskirchen) ; Meroli, Stefano (CERN) ; Poletti, Francesco (Southampton U.) ; Schmauss, Bernhard (Erlangen - Nuremberg U., Theorie III) ; Taranta, Austin (Southampton U.) et al.
This Letter reports the first, to the best of our knowledge, spectral radiation induced attenuation (RIA) measurements of nested anti-resonant nodeless hollow-core fibers (NANFs). A 5-tube NANF, alongside a solid-core single-mode radiation resistant fiber (SM-RRF), was irradiated under γ-ray up to 101 kGy (SiO2) and under x-ray up to 241 kGy (SiO2). [...]

CMS expects to manage many tens of peta bytes of data to be distributed over several computing centers around the world. The CMS distributed computing and analysis model is designed to serve, process and archive the large number of events that will be generated when the CMS detector starts taking data. [...]

Grid computing has become very popular in big and widespread scientific communities with high computing demands, like high energy physics. Computing resources are being distributed over many independent sites with only a thin layer of grid middleware shared between them. [...]

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.

Controlled overflowing of data-intensive jobs from oversubscribed sites

The CMS analysis computing model was always relying on jobs running near the data, with data allocation between CMS compute centers organized at management level, based on expected needs of the CMS community. While this model provided high CPU utilization during job run times, there were times when a large fraction of CPUs at certain sites were sitting idle due to lack of demand, all while Terabytes of data were never accessed.

Use of glide-ins in CMS for production and analysis

/On behalf of the CMS Offline and Computing Projects
With the evolution of various grid federations, the Condor glide-ins represent a key feature in providing a homogeneous pool of resources using late-binding technology. The CMS collaboration uses the glide-in based Workload Management System, glideinWMS, for production (ProdAgent) and distributed analysis (CRAB) of the data. [...]
