The 40 MHz trigger-less DAQ for the LHCb Upgrade
/ Campora Perez, D H (INFN, CNAF) ; Falabella, A (CERN) ; Galli, D (OCEM, Bologna ; Bologna U.) ; Giacomini, F (CERN) ; Gligorov, V (INFN, CNAF) ; Manzali, M (Bologna U. ; Ferrara U.) ; Marconi, U (OCEM, Bologna) ; Neufeld, N (INFN, CNAF) ; Otto, A (INFN, CNAF) ; Pisani, F (INFN, CNAF ; Rome U.) et al.
The LHCb experiment will undergo a major upgrade during the second long shutdown (2018–2019), aiming to let LHCb collect an order of magnitude more data with respect to Run 1 and Run 2. The maximum readout rate of 1 MHz is the main limitation of the present LHCb trigger. [...]

Reliability of datagram transmission on Gigabit Ethernet at full link load
/ Barczyk, A ; Carbone, A ; Dufey, J P ; Galli, D ; Jost, B ; Marconi, U ; Neufeld, N ; Peco, G ; Vagnoni, V M
The reliability of datagram transmission over Copper Gigabit Ethernet using commodity hardware at sustained Gb/s rate is crucial for the functioning of the software trigger layers of the LHCb experiment. We aim to demonstrate that a nowadays available high-end commodity PC can be employed to achieve the required network performance, in particular to implement a sub-farm controller node. [...]

The selection of B0-->pi+pi-, B0-->K+pi-, Bs-->K+K- and Bs-->pi+K- decays, which are traditionally chosen as benchmark channels to demonstrate the physics potential of the detector for fully hadronic modes, is presented. The strategy followed to identify the best selection cuts is described. [...]

LHCb can collect large samples of B0-->pi+pi-, B0-->K+pi-, Bs-->K+K- and Bs-->pi+K- decays. The sensitivity achievable on the corresponding Bs-->pi+direct and mixing-induced CP-violating observables has been studied in detail. [...]

Aim of this paper is to outline the designing criteria which guided us in the design and the realization of a computing farm for the LHCb Italian Tier-1 prototype. The hardware architecture, with particular attention paid to the disk data storage and to the disk-less implementation of the farm nodes, is described. [...]
