Flexible custom designs for CMS DAQ
/ Arcidiacono, Roberta (INFN, Turin ; Piemonte Orientale U., Novara) ; Bauer, Gerry (MIT) ; Boyer, Vincent (CERN) ; Brett, Angela Mary (Fermilab) ; Cano, Eric (CERN) ; Carboni, Andrea (INFN, Pisa) ; Ciganek, Marek (CERN) ; Cittolin, Sergio (Zurich, ETH) ; Erhan, Samim (UCLA) ; Gigi, Dominique (CERN) et al.
The CMS central DAQ system is built using commercial hardware (PCs and networking equipment), except for two components: the Front-end Readout Link (FRL) and the Fast Merger Module (FMM). The FRL interfaces the sub-detector specific front-end electronics to the central DAQ system in a uniform way. [...]

The DAQ system of the CMS experiment at the LHC is upgraded during the
accelerator shutdown in 2013/14. To reduce the interdependency of the DAQ
system and the high-level trigger (HLT), we investigate the feasibility of
using a file-system-based HLT. [...]

A flexible monitoring system has been designed for the CMS File-based Filter Farm making use of modern data mining and analytics components. All the metadata and monitoring information concerning data flow and execution of the HLT are generated locally in the form of small "documents" using the JSON encoding. [...]

The Data Acquisition system of the Compact Muon Solenoid experiment at CERN assembles events at a rate of 100 kHz, transporting event data at an aggregate throughput of 100 GB/s. By the time the LHC restarts after the 2013/14 shut-down, the current computing and networking infrastructure will have reached the end of their lifetime. [...]

As part of the CMS upgrade during CERN long shutdown period (LS1), the CMS data acquisition system is incorporating Infiniband FDR technology to boost event building performance for operation from 2015 onwards. Infiniband promises to provide substantial increase in data transmission speeds compared to the older 1GE network used during the 2009-2013 LHC run. [...]
