Description
In phase 2 of the NEMO neutrino telescope project a tower holding 32 optical
modules is operated since march 2013. A new, scalable Trigger and Data
Acquisition System (TriDAS) has been developed and extensively tested with the
data from this tower. Adopting the "all data to shore" approach, the NEMO
TriDAS is optimized to deal with a continuous data-stream from off-shore to on-
shore with a large bandwidth. The TriDAS consists of four computing layers: (i)
data aggregation of isochronal hits from all optical modules; (ii) data filtering by
means of concurrent trigger algorithms; (iii) composition of the filtered events
into post-trigger files; (iv) persistent data storage. The TriDAS implementation is
reported together with a review of dedicated on-line monitoring tools and
networking architecture.
