Description
The DZERO experiment records proton-antiproton collisions at the Fermilab
Tevatron collider. The DZERO Level 3 data acquisition (DAQ) system is required
to transfer event fragments of approximately 1-20 kilobytes from
63 VME crate sources to any of approximately 240 processing nodes at a rate
of 1 kHz. It is built upon a Cisco 6509 Ethernet switch, standard PCs, and
commodity VME single board computers (SBCs). We will discuss the running
experience of the system since 2002, the incremental upgrades, scaling
capabilities, and how physics goals have altered the way we run the system.
